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

There’s no set time limit for when you should replace your locks, but there are several indicators that it’s time to swap them. If you’re moving into a new home or have a roommate moving out, it’s smart to change the locks. If you experience a break-in or other crime, you should change it then too, or if you ever lose your keys. Eventually, locks can wear out, so it’s ideal to replace them after several years of use or one of these circumstances occurs.

Smart locks offer around the same level of safety as conventional locks with keys. The best way to secure your door locks is to combine routine locking mechanisms with other home safety features, like lighting, motion sensors, security cameras, and window and door sensors. 

Smart locks have the upper hand when it comes to convenience—you won't have to worry about your key not turning in the lock or fumbling around in your bag for your keys—but beyond that, any door with deadbolts will offer a similar degree of security.

You may be able to get a broken key out of a lock by yourself, depending on the situation. If a portion of the key is still protruding from your lock, try lubricating the keyway and using pliers or even a bobby pin to pull the key out of the hole. If you have jigsaw blades handy, you can also try using those to grab onto the stuck key and pull it out. 

But, if neither option works or you can’t reach the key, your only option is to call a locksmith for help. 

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.

A door lock service is performed by a professional locksmith, and the cost of hiring a locksmith for these kinds of repair tasks usually runs in the $100 to $250 range. It all depends on the type of locks you have, how many locks are included in the service, and where your home is located. Always choose reliable, trustworthy locksmiths, and get a few quotes before making your choice.
