Our Customer Reviews

Amy K.

Thanks to Alex for coming out so quickly and taking care of my problem.  I couldn’t get my door open as one of the lock bolts wouldn’t disengage.  He was able to replace the broken part quickly.  He also fixed an issue with my deadbolt (which he didn’t charge extra for and that was truly appreciated).  I think it took all of about 30 minutes to get everything replaced and working again, including rekeying one of my locks.  Thanks again for all of your help – Sunday at midnight isn’t exactly a fun time to be working!

They were quick to respond, quick to show up and quick to unlock and rekey our lock. The contact to completion was 3 hours. Also friendly. I hope to never need them again but if we do I will be calling them again.

We had an emergency on the friday night of a holiday weekend. I spent several hours calling and couldn’t find anyone to help out until the next morning.
Then I found these guys. They solved my problem within a half hour and charged less than the guy wanted for next day service.  The locksmith was professional and friendly and very helpful. I couldn’t ask for better service and I’m definitely keeping their card in my wallet from now on.
So very happy.
