"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."

"From start to finish my experience was fantastic. They were so fast with communication and actually offered an earlier appointment than I had scheduled. Our technician, Keegan, was so professional and was able to quickly diagnose and repair our electrical issue. He additionally offered great recommendations to make sure we are within code for our rental property. He was very knowledgeable and efficient."

"I was amazed at the professionalism, prompt service and response. I called and he was at my location in under an hour and had me ready to go in approximately 1.5 hours. I was able to get a price over the phone for what I needed done with no unexpected extra charges. He made a door key as well as the key for the ignition."

"The manager of the grocery store recommended her to call John and his company.  Boy was she glad she did!
John told her  he would be there in about 25 minutes. He was there in 22 minutes and in about 30 seconds he had her car unlocked. No damage to window, the rubber seal, or the lock. He was a lifesaver for her and the groceries!
She said he was very calm and professional. He was also extremely reasonable!  He only charged her $50 when he could have charged way more for someone in that kind of situation. She was very impressed and I am too. We highly recommend him.

Locksmiths FAQs, answered by experts

Keyless locks are great for convenience, letting you unlock doors with a code or your phone so you don't need to carry keys around. They also often come with helpful features like temporary codes for guests. On the downside, they can be more costly up front and do require batteries that will eventually need replacing. If you value ease of use and additional security features, keyless locks are worth the investment.

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.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

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.
