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.

Owner operated. No subs. Charges by the hour.

"Art has done a number of projects for me over the past several years. From installing an outdoor light fixture, re-attaching an indoor stair rail, securing loose hand shower bar, to recommending matching grout color for repairing grout that was crumbling in spots, Art's work has always been top notch. Growing up, my father was a perfectionist and always went the extra mile to repair things right. Art is the same way. He will do things right, and if it is something he doesn't feel confident about, he'll let you know that too, rather than trying to tackle something that he isn't sure he can do right. Highly recommend!"

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

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.

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.

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.

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.

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.
