"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths questions, answered by experts

Many local hardware stores have the equipment to copy basic keys at a low cost. Some locations may have freestanding machines where you can pick out a blank and insert it and your original key into the duplicating machine.

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

It could be difficult to get in and out of a lock for several reasons, such as the keyhole needing additional lubrication. Particles, debris, and dirt can also get into a lock, making a key stuck (the lubrication can help with the removal). 

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.
