"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."

"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 questions, answered by experts

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 And like all electronic devices, outdated models are more prone to problems and safety concerns.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.

As with any computer, smart locks can be hacked by someone with the technical skills to do so, but most people do not have that ability, making smart locks relatively safe. If you have any concerns about a compromised smart lock, opt for an encrypted smart lock, change your Wi-Fi password, and make sure that you only give out your password to trusted family and friends.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.

One of the best tools for removing a stripped bolt is a handy pair of locking pliers. Locking pliers can usually grip onto screws with a broken, rounded, or stripped head and lock in place so that you can loosen even the most stubborn bolt that would otherwise remain hopelessly jammed.
