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

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

Although you should rekey your locks after moving into a new home, you may feel more comfortable replacing the locks entirely. Here are some other scenarios when you should replace your locks rather than rekey them:

  • When someone moves out of your home.

  • There are too many copies of the existing key.

  • Your home experiences any type of break-in.

  • You lose your key with the address on it.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

Typically, it can take around 15 minutes to rekey a lock. The time depends on the type of lock and how skilled you are at rekeying. The first time you rekey a lock, it may take a little longer. Once you get the hang of the process, it will move along much more quickly.
