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."

"Very helpful! Because they don't normally do that, they just do towing for cars and trucks but they helped me. They didn't have to help me but they volunteered to help me."

Locksmiths questions, answered by experts

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

Find a vetted and trusted locksmith to work on your home so you can feel comfortable and safe. Hire a professional with these qualifications:

  • Search a verified directory of locksmiths near you, like those on Angi. 

  • Check for an Associated Locksmiths of America (ALOA) logo on their website or company logo.

  • Read company reviews. You can also check their social media pages.

  • Ask for a pro’s credentials, insurance, licensure, and customer testimonials. 

  • Check if the locksmith is knowledgeable about various topics, from decorative locks to the newest technologies on the market.

Rekeying door locks yourself costs a fraction of what you would expect to pay a locksmith. On average, it costs between $50 to $100 to hire a local locksmith to rekey your house, though labor costs may vary based on where you live. For a DIY solution, you can expect to spend $11 to $25 on a rekeying kit.

Locksmiths recommend changing your locks once every seven years for the best security at your home. Locks can wear out over time, so you should inspect your locks regularly. A higher grade lock provides you with more cycles than those with a lower grade.

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.
