"It went great. They could have had a serviceman at my location within an hour. Instead the serviceman, Joshua, called to make sure I needed the service and approximately what it would cost to repair it. Instead, Joshua knew what the issue was and told me how to repair it myself. It's not so much that I got away without paying a minimal service charge, it's that I found a contractor I could trust. They will be my go-to locksmiths from now on."

"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"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."

"Chris was excellent! I highly recommend. We had a problem with our front door, literally for years. It continued to get worse and worse until it became a real problem. Chris and I diagnosed the problem, and Chris fixed it beautifully. It is such a pleasure to have our door work as it did when it was installed. He was prompt and went above and beyond. I will definbitely utilize Chris in the future"

"Stanley was a great person to work with.  He was prompt and worked hard to get all of our locks on the same key and in working order.  We bought an older home and the previous owner had a different key for each door, he was able to put all doors on the same key and special ordered a cylinder for one of the locks as it was giving us trouble and an original lock dating over 70 years.  We appreciated all of his work and recommend him to anyone looking for a locksmith."

Locksmiths questions, answered by experts

Regrettably, entirely pick-proof locks don't exist unless you opt for keyless varieties. Locks advertised as "pick-proof" are, in reality, more resilient against lock-picking and bumping attempts because of complex mechanisms consisting of pins and sidebars. These locks work like this—they assign two tasks to the key, enhancing security by making unauthorized entry more challenging.

Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.

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.

Security systems are one of the measures that deter burglars the most. Research suggests most burglars look for signs of a security system before going in, although the presence of a security system doesn’t automatically mean they won’t enter the home. However, a security system with cameras can decrease the chance of a burglary overall.

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.
