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 made the call after reading the reviews. My call was answered promptly, we scheduled a time and date. The locksmith arrived within the agreed upon time window. I explained what we needed and he got right to work. He was polite and professional. He finished the job in a half hour or so. I'm very pleased with the work and the experience."

"My safe wouldn't open they said a couple of drill holes and it will be easy. Guy showed up. Spent 6 hours cut dial and another large hole in safe still didn't open. I asked him. To see if we can push safe and maybe take pressure off one side and it opened. Destroyed safe . They offered another safe then said no they will have a welder come and weld cut off prices on. I said that won't do it and asked for 1st option, replace safe. Then they sent letter from attorney for payment. These guys suck."

Locksmiths questions, answered by experts

It’s best to avoid using oil-based lubricants within a lock because they attract larger amounts of dust and debris. When this occurs, it can make it harder for you to operate the lock, or it can even cause damage to the internal locking mechanism. A dry lubricant is the ideal solution instead.

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

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.

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

Rekeying a lock is less expensive than replacing the whole unit. The cost to rekey is about $50 to $100 when you hire a pro or as little as $10 if you DIY. The cost to change a lock is $130 to $500, depending on the hardware you select.
