Very happy! read more

Dude was on time, personable and expedient. If you need a locksmith, look no further.

Provided a convenient service at a fair price. Reprogrammed and cut a key for Acura MDX. Price was fair considering he comes to your place of business. Others seem to decipher what you're willing to pay and give lots of if ands and buts. John was a straight shooter. read more

John was super responsive! I called in the morning and he had availability in the afternoon. He was on time and had good recommendations on changes to the locks.

John was by far the best locksmith I've ever hired. Not only was his price LESS THAN HALF of all the other quotes but he communicated when his job before me ran a little over and was going to be 9 minutes later than quoted time.

We reached out to John on a Sunday inquiring about installing a patio door key lock not expecting to hear back from him right away. However, we heard back the same day and scheduled him to come out the next day on Monday. We unfortunately purchased the wrong lock. However, John worked diligently to customized the parts to get the lock to work. We were very pleased with his professionalism and diligence to get the work done properly. We would highly recommend him for anyone needing a great locksmith and will more than likely use his services again. read more

I talked with 4-5 other locksmiths and this guy had a FAR lower quote and more importantly he was responsive, helpful, and overall just a humble guy. He programmed my new car key quickly as well. 10/10 on service and a 12/10 guy. Would highly recommend them for any key needs! read more

Absolutely disgraceful company! I was locked out of the car. I called this company to help me out. We agreed on $125 for two keys. The employee named John came with a rude attitude. He unlocked the door and then lock the car. I quote him "Pay me to unlock the door for $65 OR Pay me to give you a key for $120" and we got into an argument that we agreed on $125 for two keys. John said "I am just doing my job" and that reflects poorly on this company. Find another better company with a respectful reputation. He has absolutely no respect for my mother. read more

I've been putting off getting second keys replaced for two cars because it is so expensive. I'm so glad I found John. He sourced the blank keys with fobs then came to the house to cut the keys and program the fobs. I'm guessing I saved about 50% over the dealer cost. John is responsive and reliable. read more

What an a.. hole. I called to get information but he told me I wouldn't understand because it'a too technical and just to believe it would work. The jackass that answered the phone was condescending and rude. He just lost my business. read more

So quick and affordable! I called 4-5 other places before finding Rocky Mountain Security Group and they, by far, offered me the best price and got me back in my car in about 30 minutes. My technician was so friendly and kind, I made sure to take his card so I can call them first next time something happens. I can't recommend them enough! read more
