"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

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.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in. 

Over time, latch components may wear out or get grimy, leading to this problem. First, check for dirt, dust, or debris in the latch mechanism to ensure smooth operation. Use an aerosol duster and lubricant to clean and loosen. You may also need to tighten the screws in the component, adjust the strike plate, or replace the lock. If none of these steps resolve the problem, consult a professional locksmith.

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.

Yes, with better technology now available, it’s possible to add a smart lock on your sliding glass door. Smart locks can be easy for almost everyone in the family to operate and can connect to other safety features in the home, like smart lights. Plus, they’re harder for would-be criminals to pick. However, keep in mind that smart locks can potentially be hacked, and some completely rely on phones or Wi-Fi, which can be an issue if the power goes out.
