Lock Services in Madera, CA

Spare keys — they can be lifesavers. When you need to make duplicates of your keys, stop by GBS. We offer lock services in Madera, California. From home copies to vehicle transponders, we can craft customized key sets here at our store. Save time and maintain your peace of mind.


Key Copies While You Wait

Make sure you have access to the things you most value. At our hardware center, we use the latest equipment and technology to make accurate copies of door keys. Many of our key copy services only take a few minutes — a moment that can save hours and uncertainty in the event of a lockout.

Every key needs a lock. When you buy a new lock at our store, we can re-key it at no additional cost. Or, if you prefer to re-key one of your current locks, just bring it in and we'll re-key it for a small fee.

Now Selling Vehicle Transponders

Today's vehicles make keyless entry a standard feature. Now, you can get a copy of your car's transponder or proximity at a price lower than the dealership. Our hardware store sells and programs these devices for most late-model cars and trucks.

We offer DURACELL keyless entry systems.
