This company is amazing, we had a last minute emergency in two of our stores to change locks because an employee left. We called them and the owner was booked but he found a way to fit us in. They were willing to work with us even when they were short staffed. They send an amazing employee in a hour he had changed and rekeyed both stores. The service from the first call to the job being done was amazing and you will not beat the price they didn’t even charge us extra because it was a last minute thing. Thanks guys.

Had a deadbolt installed, and a couple other locks fixed without being scheduled. The locksmith, Joe, called 10 minutes prior to our appointment time. Joe was very professional and went out of his way to accommodate my disability problems. If I could give 10 ☆☆☆☆☆☆☆☆☆☆, I would. Highly recommended and very affordable.
Thank you Interstate Security.

Called and asked for a lock re-keyed, scheduled my appointment for the next day, and got a call back about an hour later saying they could stop over in 20 minutes and take care of it! The gentleman showed up, fixed my lock, gave me some copies of the new key and was done in maybe 15 minutes! Reasonably priced as well, I'd definitely call these guys again for sure! Thanks again!

I walked in with an obscure key from a 25-year-old truck and walked out 15 minutes later with keys that worked perfect. They do a lot with safes and other complex security work. Highly recommended.

Have had dealings with them on several occasions over the years and they've been wonderful! Their prices are fair in my opinion. I'd rather pay a little more to get it right and the professionalism instead of paying less to get less. I've always been treated as a person not just a number by them. Highly recommend them to everyone!!
