My sister and I were locked out of our Auntie's house, which is where we were staying for the weekend. Gave him a call around 8pm and he was here by 8:10. We were also short on cash due to the fact that it was so unexpected. Not just did this man get the screen door and the wooden door open in a matter of 10minutes, he lowered his pricing in order to compensate for us being short on cash. Excellent service, I honestly don't think it gets any better than this. Thank you so much. read more

SO IMPRESSED!!! I needed the ignition cylinder replaced in my vehicle, and had called several locksmiths, all of whom either gave me astronomical estimates or made excuses as to why they couldn't show up at the times initially set. Felt like they really didn't want to work or they thought I was some gullible rube eager to throw money their way. However, when I connected to Mario, he gave a more than reasonable estimate and offered to drive over immediately from Fremont to Castro Valley even though it was nearly 6pm and traffic was horrific. He showed up as promised, performed a miracle in about half an hour, and didn't try to pad the charge- he kept his word all around. I'm always impressed by fabulous customer service, and Mario and his Authority Locksmith Service were godsends...couldn't ask for anythimg more. read more

I needed a rental property re-keyed. Mario answered my call immediately and agreed to come out the next day, which was a Sunday by the way. Not only did Mario rekey the house, he also fixed two sticky locks, two sticky doors and informed me that one of my locks was not up to code and replaced it, which I had no idea about. Mario made sure I understood everything he was going to do and explained every charge. The work was done very quickly and neatly. I would call Mario again. read more

It was 5:30am and I locked my keys in my car at the BART station. They were in plain view so I needed to get them out quickly. I called a lot of businesses but no one picked up. Finally I called Autority Locksmith and Mario picked up immediately. He arrived within 15 minutes and had my car open and my keys in my hand in 30 seconds. Thanks again Mario for the fast and friendly service. I know who to call first next time. read more

Mario has helped me two times. The first time I needed the door unlocked and a key made to match the front door. The second time I needed it unlocked and a new cylinder and key. He was on time both times and he's a really nice guy. I have never needed a locksmith before but I hear it's really expensive and that a lot of people had problems with prices increasing once the locksmith was there. So I was really worried to hire a locksmith. But Mario's prices seem reasonable to me and I'm happy with his service. read more

I got locked out from the door to my garage on Sunday morning. I found Authority from Yelp and decided to give it a try since it was located about 2 miles from where I live. I called and talked to Mano, he asked for the type of lock and my address, then he said he was on his way. He showed up at my place in just about 10 minutes with a great friendly smile. He got his tools out immediately and was ready to help. Best of all, he only took 3 minutes to unlock my door. Thanks Mano, will definitely recommend your service to my friends and neighbors. read more

When he arrived at the job site he changed the estimate and said will break a few locks and will charge $40.00 each. i told him he cannot break I just want him to give me the keys to all the rooms I think the job was too over whelming for him After doing the site visit and spending almost an hour he comes and cannot handle the job He was not professional at all and could not handle the job. he was extremely rude and left Seema read more

I'm glad I found Mario on yelp, finding a locksmith to replace an ignition sounded super expensive prices ranging from 250-400 depending on the vehicle, pretty outrageous for a 1998 Toyota Camry. I came across Authority Locksmith which had really good reviews, so I gave them a call, I told Mario exactly what needed to be done and he gave me the estimate which was super cheap compared to all the other businesses I've contacted. He came 10 minutes after I sent the address over and the job was done in a matter of minutes, he will definitely hear from me again, and I'll surely pass his number on to anyone who is in need of the same services he provides. Thanks A Lot Mario!!! read more

Arrived within 20 mins after I called. They are really professional. Im highly recommend. Thanks!

HIGHLY RECOMMEND!!! Mario arrived within minutes of my call, I needed an ignition key. once he arrived he noticed my trunk wasn't fully closed due to a crash accident on my car so he offerered to make it close and open for a few extra bucks and so he did. He made one key for my ignition, trunk, and doors (note that my ignition key was different from that of the trunk and door). Would highly recommend to anyone, very fast and nice gentleman, mario is the man to go to. read more

Great service, fast and very well done. Mario is definitely amazing at his job... I recommend him no doubt he earned these 5 stars

I got locked out of my house this morning (Sunday) and after failed attempts to regain access to my home I found Mario on Yelp and he was at my house within 15 minutes of calling him! Thank goodness because it was freezing out. He had to climb my fence because my gate is pad locked with the key locked inside my house. He truly was a savior today- and his helper (she was stuck on the other side of my gate). He also cleaned up from the mess of having to break my lock off - I installed a keyless lock 2 days ago, and I forgot the code this am (pre-coffee!) - this was the only way to get back I'm. I highly recommend! Rate was very reasonable especially for a Sunday read more
