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

Replacing your locks isn’t always a necessary option. You can usually save money by rekeying locks instead of replacing the hardware. You should consider rekeying the locks instead of replacing them in the following scenarios:

  • You want to upgrade your existing locks.

  • You have a lock you don’t want to replace.

  • You recently bought a home and want to change the locks.

  • You lost your key.

Locksmiths recommend changing your locks once every seven years for the best security at your home. Locks can wear out over time, so you should inspect your locks regularly. A higher grade lock provides you with more cycles than those with a lower grade.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

When it comes to how to get a stuck key out of a lock, the simplest way is to use some kind of lubricating substance. One option is to apply graphite powder while wiggling the key gently. As the graphite fills the lock, jiggling should loosen the key enough to allow you to pull it out.

Various types of deadbolts are available, from the classic single-cylinder lock to a double-cylinder, rim deadbolt, smart deadbolt, and electronic deadbolt lock. Most homes in the U.S. use a single-cylinder deadbolt lock, which requires a key on the exterior and only a thumb turn on the interior to open or close the lock.
