"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."

"ADT is the best company 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."

"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

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 However, replacing the lock if it is severely damaged, outdated, or lacks security features may be a better long-term investment.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.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

Begin by checking the power source, typically a battery or wired connection. Ensure the battery is installed correctly, has sufficient charge, and isn't corroded. If it's a wired lock, examine the electrical connections to confirm they are secure and free from damage. Additionally, inspect the lock's programming or settings. Confirm that user codes or access credentials are programmed correctly and that any remote control devices are paired and functional.

Rekeying is typically cheaper than replacing locks. Professional rekeying costs between $40 and $160, sometimes with an additional fee of $15 to $40 per lock. A locksmith's hourly rate averages around $75. If you do it yourself, a rekeying kit can cost as little as $10. In contrast, replacing a lock costs between $130 and $500, with an average of around $315, depending on the hardware and lock type. Rekeying is a simpler process that changes the key for your existing lock without replacing the hardware. It is a good option if you have a quality lock that works well, you've recently moved, you've lost a key, or you need a quick security upgrade. The best choice depends on the condition of your current locks.

Rekeying your own locks is a low-cost task that prevents you from having to replace the locks themselves completely. The first couple of times you rekey a lock may be challenging because this is an intermediate DIY task. You can purchase a rekey kit from most hardware stores, but make sure you’re buying the kit from the brand of lock in your home that you’re going to rekey.
