The second time was to copy a completely non-electric key for a 20-year old car (another place had wanted $50, then $35 each?!!), they did it for $9 each and he even tested the keys himself before I paid.

He asked for pictures of the lock and door jamb and gave me some diagnostic tests, all so he could make sure he knew what the job would entail and make sure he had the right tools. The job overall took him about 2 minutes, but he double checked everything before starting work and flagged a few items I should look out for in the future. To boot, he's a lovely guy with a very interesting background with a ton of specialized knowledge and training. I will absolutely call him for my next locksmith needs.

For me it's those two things that really stand out. Customer service and "it just works." In terms of customer service, it's hard to do better. The company's response time to questions is very fast. That's pretty much what you want. As for "it just works," the Alarm.Com system and equipment they are a dealer for really gives you peace of mind. It's actually secure.

They argued that there was a 3 days cancellation policy; this 3 months after my 3 year contract has ended. I have to yell for them to promise a refund for only 1 month. I am holding my breath. If this goes on, I will take them to court.
