"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."

"Technicians examined my garage door and diagnosed the problems with it. They completed repairs the same evening and I had a brand new motor assembly which is quiet and working perfectly since. They do nice work."

"Front Door locks broken on my home. Had to take off work, no way to secure my home. Home Advisor put me touch with Colonial Lock Service, Inc. the gentleman on the phone tried to help trouble shoot the problem when that failed a locksmith was dispatched. The locksmith called and said I will be there in an hour. This young man showed up on time and said don't worry I hear to make it better. He had such great friendly personality and did a great job. He replaced both of my locks and said "Sir your new locks turn like butter now". Well that made my laugh but he was so right, my locks never worked so good. It appears when the door was replace 15 years ago the locks never really lined up right. The replacement locks were are not your local hardware style, much better quality. I was quoted a price which having never used a locksmith before I thought was high, however the quick response, great service, better then average hardware and most of all the locksmith had a great friendly attitude. The price was right. This young man shook my hand and thanked me. Right when I thought there was no more good customer service in this world, WOW!"

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.

In some cases this is possible, but it’s not advisable as the screwdriver is likely to leave marks all over the wall and a noticeable dent on the door. Move slowly and carefully if you have to use this method, and consider calling an emergency locksmith right away instead of trying to break in.

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.

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.

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.
