"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."

"Rafael was great - he fixed our front door knob and lock, replaced another door handle, and our towel bar. He worked us into his busy schedule and came by on a day that was best for me. Rafael picked up parts he needed at Home Depot after assessing what we needed, and efficiently completed all three jobs."

"Jermaine is one of those handymen who is worth their weight in gold. I hired him and his team to perform a variety of odd jobs around my newly purchased house, and they stayed late - on a Friday afternoon no less - to successfully install appliances that Home Depot was unable to install (appliance installation was not on my original list because I didn’t think it was something Jermaine’s group did). All work Jermaine and his team did met or exceeded my expectations, and the entire time, Jermaine was focused on doing as much for me as he could. I will 100% hire Jermaine again the next time I need a handyman, and you should too."

"We've hired them for multiple projects. All done with the highest professionalism. Our projects included a baluster to our basement (With an extra railing for our two year old!). In addition, they helped us install closet doors that needed to be trimmed to fit properly. Would highly recommend."

Locksmiths questions, answered by experts

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.

It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.

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. 

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.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.
