"This is the second time we used John. Since he was so good on our first project, it was an easy choice to call him again. This project was to replace rotted wood posts and railings on our front porch. As usual, John’s work was excellent. His attention to detail clearly separated him from many other contractors. John is easy to work with, does what he says he will do, communicated well, consults with you on any decisions and handles unexpected issues with ease. We will use John again for sure."

"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."

Locksmiths FAQs, answered by experts

It depends on what type of keyless entry it is and if the locksmith has the proper tools to remove a keypad entry lock since some are more advanced than others. However, locksmiths can typically work around keyless entries to vehicles, so it depends on what type of keyless entry system needs opening.

One of the best tools for removing a stripped bolt is a handy pair of locking pliers. Locking pliers can usually grip onto screws with a broken, rounded, or stripped head and lock in place so that you can loosen even the most stubborn bolt that would otherwise remain hopelessly jammed.

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

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.

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.
