Did a great job, drove over an hour to fix my truck and get us on the road again. Fast, reliable, easy to setup. read more

Time to bite the bullet and get a car alarm. I did a lot of research. And after reading a lot of reviews, I went with on-site auto alarms. I'm glad I did. He was very knowledgeable. Very helpful. I was able to drop my car off the night before. He explained the new system to me very thoroughly. I wouldn't hesitate to get another system from him in the future. read more

very knowledgable, recommended a better security than i asked, he fully explained, can't say he left anything out. there is a lot to it so it's hard to remember. and gave me options for settings that must be coded. lots of great tips read more

Had my truck alarm installed by On-Site Auto Alarm and I couldn't be more pleased. Cooper E. showed up right on time, super friendly, and professional. He got the install done quickly and so clean you'd never know anything was added. He even took time to show me how to use the new Viper system before leaving. Lifetime warranty on the work and one year on the equipment -- awesome peace of mind. Highly recommend these guys! read more

Wow-I'm impressed I originally asked Cooper about putting in a Viper alarm, and after looking at the upscale option of Drone, I chose the deluxe CMX module/package and I love it! The Remote start is a sweet option--it was a cold day but it became toasty warm inside in 15 minutes and the windshield ice film was defrosted. Normally anyone could walk up and steal my van with my tools while it sits outside warming up--but now it's locked and armed with remote start. I could have gone to Best Buy or any other car alarm installer, but I googled just for kicks and saw this guy with 4.9 stars and read several reviews and so here we are! Mostly wondering why I waited so long. Already had two break-ins over the years and another attempt with a crowbar, so now I feel safer. When I walk up to my van it unlocks the doors and turns alarm off automatically, using the proximity feature. Better to have an amazing thousand dollar alarm system than losing $3000 worth of tools--again! I didn't hesitate after meeting with Cooper at his facility. He is meticulous about the things that matter and loves doing this work. He'll be around when I have questions or need service. Three questions we might ask ourselves before doing business with a new vendor... 1. can I trust you? 2. are you good at what you do? 3.do you care about me? I trust him, he's excellent at what he does and he really cares that I'm satisfied. He seems to know this overlooked rule: The only thing that really matters is Getting and Keeping customers. Walt Disney wanted his guests to have such a great time that they would return - -with a friend! I will definitely return with my next vehicle and I will refer friends because I am so impressed with the Drone system and with the time, effort, energy that Cooper has put into making my installation perfect for me and for my needs. He asked several questions about what I wanted and showed me different options, never asked for any money upfront-- I was offering to pay a deposit and he said it wasn't necessary, I'm kind of a stickler for great service and he passes with flying colors! Thanks Cooper! kevin read more

Onsite Auto Alarms - giving Cooper a thumbs up - Car Stereo Installation Near Me - Phoenix, Arizona

See all

Professional and experienced alarm installer. Price was fair and delivered as promised.

Great work! Thanks for your detailed work and instructions on how to use the alarm system.

This is the place to go. Very fair pricing and excellent communication. The work is top notch as well. I will recommend Onsite for any alarm installation or repair. It's rare to find such a great company, and here it is. Thank you for a great job. read more

Stop looking for other installers for your alarm system. Call Cooper and get on his schedule. Do it. You will be amazed at his attention to detail. His installs are a work of art and he takes the time to educate you about every little detail. With my install, I forgot to mention I wanted the turbo timer feature. He told me he already had the harness done and he'd have to undo the whole thing to run the extra wires. Well he called me back 2 hours later and asked me what settings I wanted for the turbo timer. He didn't have to do it, but he did and I was BLOWN AWAY. He takes care of you like you're family and you can tell the pride he takes in his work. It is incredibly refreshing in this age of cheap products and people doing crap jobs to make a quick buck. It's well worth the money for Cooper's services. Stop searching and call Cooper now!! read more

Called Cooper the beginning of the week on an older GMC Yukon vehicle. Alarm was acting up for the last two years going off whenever it wanted to killing the ignition. He made an appointment for 9 o'clock on Saturday. Handled the situation in about 45 minutes. I would definitely recommend him to anyone that wants an alarm put in an alarm and I give him five stars read more

Cooper was fantastic on the phone and then in person for installation. He quoted a competitive price and had immediate availability to service our sons 2006 Toyota Forerunner. He did an incredible job and had the vehicle finished quickly! Definitely worth 5 stars and I highly recommend!! read more

My car was dead in the water due an older alarm with an ignition kill. I saw the reviews for Cooper and immediately knew he was an instant hire. I called and he came out early the next day and did a fabulous job! He installed a new alarm in about an hour and made sure I had knew of and selected the options available. Definitely would recommend him to anyone! Outstanding work and great person! read more

Had a great experience getting a two-way alarm system installed in my vehicle. My vehicle was stolen about two months ago, and I knew when I got it back from the shop I needed better security. The alarm system was installed within 24 hrs of my initial call to Cooper. I am extremely pleased with his services. He also gave me tips and showed me how to utilize the remote after he was done! I feel so much better and my vehicle feels very secure now. Thank you Cooper. read more

Cooper is a true professional. Knowledgeable, speedy and went beyond what was required out of genuine concern. Battery issues, my alarm acting screwy, the hood of my truck not closing and even replacing my brake light! Highly recommended!! read more

I was able to get a booking super quick! He came to my house, explained the different packages available to me, installed everything, And called a couple of days later to see if I had any questions about the new system. I have referred a couple people to him and hopefully they've been able to use his services. I love my alarm and my remote start! read more

Cooper is a master of his trade. As someone who has wrenched on cars, his harness looming is impeccable and provides a quality product at an affordable price. Will be having him install speaker upgrades when the time comes. There is no competitor to Cooper because he is in a class of his own. read more

What can I say, that hasn't already been said. Cooper, thank you sir! So we just moved into our new apartment and as we're still bringing stuff over to the new place, he's going to town with my alarm install, talk about convenience and service. He took out an existing alarm that was installed unprofessionally and put in a new top of the line compustar unit. His wiring is by far the best. Everything looks original and you can't even see the alarm module. He added remote start to my truck and in this heat I know I am going to enjoy getting into a cool cab. Worth every dollar. Thanks again! read more

I Had Cooper install 3 alarm systems in my work delivery trucks for C&S Sporting Goods and my personal truck. He did an amazing job on all aspects of the install. He was able to get all alarms installed in a timely manner and with great attention to detail. He also took the time to explain on how to operate each system. His customer service was great throughout the job from start to finish. The best part is the customer service after the fact. I had an issue with one of my remotes and I was able to contact him after hours and he was happy to help walk me through a reset on my remote to get me back up and going. Support local and get great product and service at a fair price. read more

Onsite Auto Alarms is hands down the best in town! Cooper went far above & beyond the call of duty for my installation. I am incredibly grateful for craftsmen like Cooper who know their trade like a pro should. I will happily recommend Cooper to all my friends & family. Thanks again for your outstanding attention to detail and being of superb value. All the best! read more

Cooper came to the house and installed an Code Alarm security system in my truck today. He was very professional. The install was great. The price was very reasonable. No up sale. Will definitely recommend him to anyone that needs an alarm system in their cars. read more

Its been 1 1/2 years since he installed an alarm on my Accord and has worked flawlessly ever since. Great price Excellent service and communication Quality job done Definitely worth the money going to use him for further electrical jobs on my cars and trucks. read more

Cooper saved the day with my alarm issue. This guy came to my home asap and I will always appreciate him and his company, fast, reliable, kind and all around class act, thank you sir!! read more

A+++: Would recommend and would (will) use again. Sure I could go on and on about cleanliness, quality of work, product, etc., but here is the bottom line. Showed up on time, life time warranty on the product and his install, excellent product and workmanship for a fair price. I was a very satisfied customer that will use him again and have recommended him to friends and will continue to. Five star rating is accurate and well deserved. read more

Cooper knows what he is doing. He's experienced, professional, thorough, and meticulous. The install took a while, but he did it perfectly and carefully. This is not some kid installing alarms and stereos part-time, this is the real deal to get the job done right. I've had very spotty experience in this field before, and highly recommend using Onsite Auto Alarms. This may sound like a paid advert, but I am a real, paying customer who doesn't know Cooper personally at all... read more

Having purchased a new vehicle, I decided to have an alarm system installed. I had had experience before with other cars working with a local stereo shop chain. I went there and after asking several questions about details of the installation I became very uncomfortable. I proceeded to review Yelp and discovered On-site Auto alarms. I spoke with the owner Cooper who was professional and informative. We set an appointment for 2 days later. He showed up on time reviewed the products did a fantastic job in the installation and even called me out to look at the details of his work including location of the signal light and the details of the wiring. I have already referred 2 friends. I especially liked Coopers pride of ownership and work ethic. . read more

WOW! I can't say enough good about this guy! He came to me to attend to an alarm issue, which he quickly fixed. Then he found some other problems and pointed them out and told me why they were a problem, and how to take care of them. He charged me a very fair service fee and offered me a discount on any future services. As a result, I plan to have him do some other alarm system work on 2 of my other vehicles in the future. I'm so happy to have found this guy and his business! read more

Cooper provides just about everything one would want for a car alarm installation specialist. 1. Cooper is highly knowledge-able in automotive electronics. 2. He provides excellent communication all along the way, from asking for your input to explaining how the alarm will work. 3. He knows the strengths and weaknesses of the different modules and products that he installs and therefore saves the customer a great deal of time in the selection process. And he can explain the reasons for these selections. 4. His detail work is of very high quality, meaning that its difficult to tell that an alarm was installed, outside of the obvious features, such as blinking lights, etc.. This in itself is its own security feature, because an alarm that is more difficult to find, is more difficult for the thief to disable. Onsite Auto Alarms is the kind of business that should be used over the more standard shops. He was able to install several items on a vehicle, which because the vehicle was new, had very little online documentation available for it. If I had taken it to a different place, I don't think the outcome would have been nearly as good. read more

Cooper is an honest guy and does very good/clean work at a good price. I had very little knowledge of car alarms and initially called onsite auto alarms to get a quote after calling a few other places. Cooper helped me figure out what I needed and didn't try to sell me anything I didn't need, which ultimately saved me money. He gave me a quote and even kept that same price even though the install took longer than expected. After having the alarm for a few days, there were some features and settings I had questions about and wanted to have changed. Cooper went the extra mile to come back out to make those changes and made sure everything was right for my car! read more

Cooper is a good guy. I called him based on the reviews I read here. There was a slight snafu on his part with the scheduling, but he did make sure he was able to get me squared away on the day of the appointment. I would certainly do business with him again. He removed a crappy alarm system that came with my pre-owned vehicle. I was super hesitant to take it to one of the many "car audio/alarm" shops, as I've always had issues with Audio Express and their ilk. Cooper was professional, polite, and answered all my questions. That combined with his on-site service makes for a positive transaction. read more

Very satisfied with the service. I had an alarm disabled from my truck. Cooper has a quick response time. I called him yesterday and he was out the next day (today)! I highly recommend you give him a call. He even went over and beyond to fix a simple problem on my truck. Let's not forget the Convenience of him coming to your home read more

A recent issue with a dead battery sent me to my normal mechanic to reconnect my keyfob with my car alarm. When he couldn't help, he sent me to audio express who also had no idea how to assist with my older, after-market alarm. Desperate, I found Onsite Auto Alarms on Yelp and called to ask if they could help. Cooper drove to my office and not only did he recognize my alarm, he had it reconnected in no time. I was so impressed with his work I asked how much a new system would cost since my current system was a bit old and after about an hour and a half he had installed a brand new, affordable system with a bunch of fun new perks that I didn't have before. I couldn't be happier with my decision to call Onsite Auto Alarms and if you need a new car alarm or help with your current car alarm you'd be hard pressed to find a more knowledgeable and affordable option. Hands down, Cooper is the best. read more

I had an issue with my car (Again) and I needed to have the alarm disconnected as it wouldn't stop and I couldn't start my car. I called Cooper after reading reviews and he promised to be here in thirty minutes, on Christmas Eve no less. He arrived as promised and not only took care of my issue, he gave some advice regarding the knucklehead who did a lot of after market work on my car. Not only was there a factory alarm, but there was a secondary one. He removed all the useless wiring and I am good to go. I would recommend Cooper to anyone who needs an alarm serviced or installed read more

Cooper was quick to respond and agreed to meet us within an hour. AND HE DID! Could tell by speaking with him on the phone that he knew exactly what was needed to disable my sister's incessant anti-theft alarm system, and get her car back on the road. Price quote was precise and fair, no surprises or hidden gotchas. If you ever need an alarm guy, Cooper is it. Great job, man. Thanks for being a true professional. Tim read more

Great service! Showed up at my house after I bricked my truck by losing (stolen while traveling) my only after-market ignition fob. Had me back on the road in minutes, didn't try to upsell service or parts. After I asked, he quoted me a great price on a new security system that I will investigate further once I deal with the rest of the fallout from the robbery. I wish the rest of it was as easy to deal with as this small portion. read more

I am a big fan of Cooper from On-Site. The alarm quit in my classic convertible. Cooper came out and diagnosed the problem quickly, ordered a new compatible alarm brain and came back and installed it the next day for a very reasonable price. And he's a great guy to talk cars with while he's working. Top marks! read more

Cooper made an appointment with me for the day after I called, quoted me a great price and worked magic on my car. Not only did he replace my alarm, which was literally freaking out ever 5 minutes, but he managed to solve a host of other electrical problems in my car door. I'd call him again in a heartbeat if I needed another electrical (alarm, audio, phone installation) problem fixed or upgraded! read more

Cooper knows what he is doing! After the install of my alarm, I discovered it did not lock my gas cap cover. I called him and he almost came back that day but he wanted to do some research. We scheduled for the following week, he showed up and fixed the problem. I will use this man and recommend him to friends if I ever hear they need alarm or stereo install services. Again, this man knows what he is doing and will do it at your home! read more

I recently suffered a car break in and decided to have an alarm installed post repairs. I found On-Site thru Yelp, and decided to give them a try after reading the reviews. I can confirm all of the praise that has been conferred to On-Site. Cooper was on time, knowledgeable, and very thorough in explaining what I should expect from the alarm system that I supplied him for installation. Cooper was very up front about the install costs, and the possible need for some additional small parts for a proper install. Cooper's price was fair, especially when considering the beatiful job that he did on my install. Cooper was super efficient, and does great work. I would utilize him again without any hesitation. read more

Don't hesitate to call Cooper great guy and extremely professional he knows what he is doing! I was traveling to California from one day to the next and to top it off I'm from out town if that makes any sense but stay with me here, I needed a car alarm so I searched online and among the others I called up Onsite Auto Alarms based on the reviews. He set me up for an appointment on 4th of July! Yup I got to his places Saturday morning then he dropped me off at IHOP and with in hour he was done. Pricing is reasonable read more

Those are amazing! I called this morning to purchase an alarm system for my new car and the first thing the gentleman said was, "let me see if I can save you some money first", literally! He said I need for you to go outside and do a test, and let me know if it works. Of course I went outside and did the test and guess what? The alarm went off and I smiled instantly. I called the gentleman back and shared the good news that I have an alarm system already. read more
