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."

Vietnam veteran with over 40 years of locksmith experience. We offer full service, mobile, and emergency locksmith work for commercial, automotive and residential clients. Originally from Beaverton, OR, we moved to Seaford 2 years ago to "slow down" life a bit. Previous owner and founder of Davis Lock and Safe in Oregon is a 5 time winner of the Angie's list Super Service Award! 10% off discount for Veterans.

"John had me contact his apprentice Ben to come out to the house. Ben was pleasant and professional. He explained the work he was doing, suggested other options as appropriate, and was transparent and fair with pricing. It was not an emergency call, but I was able to be scheduled within 24 hours of calling, which was unexpected but appreciated. I will be contacting Ben or John any time I need a locksmith and recommending them to my friends."

officially established in 1985, I have been designing and building many different things since I was a child. Advertising my company as a GENERAL BUILDING/DEMOLITION CONTRACTOR is an understatement. WE do odd jobs, handyman repairs of just about anything made by man, HOME IMPROVEMENTS, and start to finish building projects.

Locksmiths questions, answered by experts

It depends on the quality of the keyless lock and usage, but in general, you can expect a keyless lock to last around three to five years. The batteries typically last around six to 12 months. The good news is most keyless locks include a low battery indicator so you can receive ample warning if your battery is about to die.

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.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.

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.
