"Jim was awesome and he called within one minute of my request from Angi. His technician ( Matt ) came out to my property exactly when Jim said he was. Matt was fantastic!! Super helpful and was very knowledgeable and communicative. Both of these guys made this experience wonderful. I’m an out of state investor and had a horrible experience with a general contractor and these guys came through to change the locks out for me. I will definitely use them again and I already let my out of state investor buddies know about them."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Locksmiths questions, answered by experts

It depends on the quality of the keyless lock and usage, but in general, you can expect a keyless lock to last around three to five years. The batteries typically last around six to 12 months. The good news is most keyless locks include a low battery indicator so you can receive ample warning if your battery is about to die.

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.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.

Rekeying your own locks is a low-cost task that prevents you from having to replace the locks themselves completely. The first couple of times you rekey a lock may be challenging because this is an intermediate DIY task. You can purchase a rekey kit from most hardware stores, but make sure you’re buying the kit from the brand of lock in your home that you’re going to rekey. 

A deadbolt lock is typically considered more secure than a regular lock based on its internal construction. Each deadbolt type has varying levels of security, ranging from withstanding a small amount of force to those that can take on multiple strikes and greater force. Regular locks provide little to no security and are typically used more for easy entry and simple installation.
