What We Do

Specialized In Locksmith Services


You must already know that getting locked out of your house during winter when the temperatures drop isn’t fun at all. Even in the summertime, realizing that your key is lying on the lake’s bottom is quite frustrating! That doesn’t mean you should go breaking any windows. What’s more, if your key was stolen or lost together with your ID, we highly suggest rekeying each of your locks. Has your house been burglarized? Perhaps your door has been kicked in, and there’s damage to your jamb or door frame? Prime has the right solution for you with their door jamb reinforcement kit that can fix the door and frame and prevent it from happening again.

If you’re a homeowner, it would be prudent to replace the original locks since they’re not designed to protect the house against intruders.
