"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."

"I was told arrival time would be 30-40 minutes. It was much longer (over 1 1/2 hours). But he did a fine job when got there. The real problem was the home advisor system. I had multiple companies contacting me and after I contracted with one, another called and lied, saying the locksmith in route did not work for company and saying he was coming instead. What a fiasco. I was at work and had just had a home break in. It was atrocious. I will not use home advisor again."

"Not the greatest results - I have used this company before and been very pleased. They were pricey, but the quality of the work was worth it. This was not the case this last time. The technician cracked the door jamb in two places while replacing the door, left paint splatters on the floor and on the side of the door which was not supposed to be painted and messed up the handset on the door. He did repair most of these issues (the paint splatters I cleaned up myself with paint thinner), but since he worked by the hour I ended up paying for that too."

"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."

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.

It depends on the quality of the keyless lock and usage, but in general, you can expect a keyless lock to last around three to five years. The batteries typically last around six to 12 months. The good news is most keyless locks include a low battery indicator so you can receive ample warning if your battery is about to die.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.
