If your house roof leaks you call a roofer when your car engine breaks you call a mechanic. Some jobs are better left to the experts who are skilled to handle the job appropriately. Similarly, call us when you require Car Key Replacement. You will find that like the roofer or the mechanic, we have what it takes to do a great job because this is what we specialize in.

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."

"I needed the lock replaced on the door that leads from the garage to the house. I called them and arranged a time. They came out, replaced it, and I was quite happy. The only wrinkle is that I think it's better to come a bit late than too early. I had other things to do but returned early, and I'm glad I did because he was early, too. Maybe specifying a range is safer. They did a great job, and I will hire them again."

Locksmiths questions, answered by experts

A smart lock is a variation of a traditional lock, and since it uses similar locking mechanisms, it’s technically not any safer. The difference is that a smart lock requires a login instead of a physical key. Some smart locks have added safety features, like shutting down after too many attempts with the wrong code. Some smart locks are considered harder to pick than traditional locks, which can further deter intruders.

A deadbolt has a different design, construction, and security level than a regular lock. Regular locks are mostly used for interior doors around the home, like bedrooms and bathrooms, and they usually include a locking mechanism on the inside. While regular locks are easy to use and install, they provide little security. 

A deadbolt adds a layer of security and is most commonly used on exterior doors. The installation is typically more complicated, but they hold up to wear and tear.

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.

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.

Changing door locks is a task that most homeowners can accomplish on their own. Standard door knobs are quite straightforward, and even more advanced locks, like electronic or smart locks, generally come with instructions. That said, the process can be time-consuming, especially if you plan to replace multiple locks around the house. It’s also a task that you want to complete correctly, considering that it affects the security of your house. That’s why hiring a pro is often best when changing your door locks.
