"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."

"I would highly recommend Walter Russell of A-Handyman. He was very prompt and accurate when providing an estimate. When the door that has been purchased for the rear of my home, didnâ t quite fit right he made it work and came back to finish the trim. I asked him about the possibility of putting up shutters I had taken down to paint, and next thing I know he had them done. He was very reasonable and reliable. I wish I had found him before working with someone else and other doors I was replacing."

"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"

Locksmiths FAQs, answered by experts

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

Yes. Most deadbolts purchased from a home improvement store include a step-by-step installation template that is easy to follow, even for novice DIYers. One of the most important steps for successful deadbolt installation is having the proper tools to start with and carefully measuring prior to any attempts at installation.

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

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

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.
