"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

Locksmiths questions, answered by experts

Locksmiths recommend changing your locks once every seven years for the best security at your home. Locks can wear out over time, so you should inspect your locks regularly. A higher grade lock provides you with more cycles than those with a lower grade.

Proper door lock maintenance includes keeping the locking mechanism clean and clear of dirt, dust, and grime buildup, lubricating the lock annually, inspecting and tightening the lock regularly, and treating the door with care. If your maintenance reveals problems, it may be time to replace the lock or have a professional inspect it.

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.

Most door knobs can be removed with a Phillips or flathead screwdriver. If you don’t have either of those available, a paper clip or small pin can sometimes work, but the extra effort may not be worth a quick trip to the hardware store.

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.
