"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."

Locksmiths questions, answered by experts

The cost-effectiveness of fixing or replacing a door lock depends on the severity of the issue. Repairing a minor problem, such as loose screws or a need for lubrication, is usually cheaper than replacing the entire lock. However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment. New locks often have improved security features, enhancing your property's safety.

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.

The easiest way to pick a lock is by using a titanium rake pick. This type of lock pick comes in a variety of shapes used to simulate different key configurations but generally has a tip with a bent design. Rake picks are the most beginner-friendly lockpicks and the simplest to learn how to use.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security.
