"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."

"There were many things wrong in my computer (my fault and letting grandchildren on computer) Robert was so helpful, gave me many good instructions to keep everything safe, which I have written down, feel like I have a new computer. He was so excellent and experienced, took his time and was meticulous about what needed to be done. He was a pleasure to work with and I will use this company again! Linda Disy"

"Choice responded quickly but the insurance plan does not pay for all doors to be re-keyed unless you have very few locks. The number of locks covered by the insurance is determined by keyholes, not doors! (Read your policy!) You will likely have to shell out some money to have this essential new-home service if you have more than four keyholes. The locksmith they called was EXCELLENT and made all our locks completely functional. We will happily hire the locksmith again (R.L Locksmith LLC). We paid $201.81 (plus another $50 for some door re-alignment not included in the re-keying benefit) and Choice paid $100 for the job."

Locksmiths FAQs, answered by experts

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.
