"Do not use this guy. He replaced a quality lock with a cheap deadbolt and door handle charging me $250.00 and stole the lock he replaced. Shody work, made a huge mess in my house and didn't have plastic covers to collect all the woodchips from drilling unnecessarily into the door. Kept telling me that his work is guaranteed and when I called him back saying the door rattles in the wind, he said to get weather striping. When confronted on the theft of the original door lock, hemed and keep talking that he could not remember taking the brand new door lock I wanted to return to HomeDepo. I was considering calling the Police. Run from this con-man."

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

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

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

Deadbolts are solid and durable as can be, but the pin and tumbler can still be forced open, thus making this type of lock susceptible to picking. Most types of deadbolts are harder to pick than a traditional spring-based lock, though. It requires a specialized lock pick and a tension wrench to align all of the pins, thus unlocking the door. 

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.

The most secure lock for a front door is typically a deadbolt. There are many types of deadbolts to choose from, the most basic of which is the standard single-cylinder deadbolt. This is the lock you find installed on most front doors. For added security, you could go with a double-cylinder deadbolt, which requires a key to operate the lock from both the outside and the inside.
