"I would like to recognize employee Doug A at SafeStreet/ADT. We’ve had an old security system sitting in our house for over 15 years without service or functionality. He took the time to explain the differences between how the old systems work and how the new systems work. He was patient with us, and we are happy customers."

"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."

"It went Perfectly. Joe arrived right on time and made sure he was parked in a good spot (I live in a co-op with a lot of rules about such things). After inspecting existing parts he told me that the knob and deadbolt were of very good quality and recommended just changing the lock cylinders. He did just that and happily honoured an Angies list coupon (even though I was unable to print it). His honesty saved me well over $150.00 He took his time and was not in a rush, sort of how you might remember skilled craftsmen from the past. He answered all my questions and made sure all worked perfectly before leaving. I will definitely hire Joe again and can recommend him highly. He also happens to be a very nice guy."

Locksmiths FAQs, answered by experts

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

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.

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.

Lock picking is a relatively subtle method of unauthorized access, making it hard to detect. But there are telltale signs to look for. First, look for scratches or tool marks around the keyhole or the lock's surface. Also, check for loose or misaligned components, like a wonky strike plate, which could indicate tampering. Consulting a locksmith or security professional for an assessment can provide valuable insights, too. Investing in high-quality locks and considering additional security measures, like security cameras, can help deter potential intruders and enhance your overall safety.

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.
