"This is the second time we used John. Since he was so good on our first project, it was an easy choice to call him again. This project was to replace rotted wood posts and railings on our front porch. As usual, John’s work was excellent. His attention to detail clearly separated him from many other contractors. John is easy to work with, does what he says he will do, communicated well, consults with you on any decisions and handles unexpected issues with ease. We will use John again for sure."

"Walter and Glen at Protect Your Home Group with ADT are the best people to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

Locksmiths FAQs, answered by experts

Security systems are one of the measures that deter burglars the most. Research suggests most burglars look for signs of a security system before going in, although the presence of a security system doesn’t automatically mean they won’t enter the home. However, a security system with cameras can decrease the chance of a burglary overall.

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.

Yes, with better technology now available, it’s possible to add a smart lock on your sliding glass door. Smart locks can be easy for almost everyone in the family to operate and can connect to other safety features in the home, like smart lights. Plus, they’re harder for would-be criminals to pick. However, keep in mind that smart locks can potentially be hacked, and some completely rely on phones or Wi-Fi, which can be an issue if the power goes out.

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.

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.
