"This was a great experience! Zach from Surface Experts was wonderful from start to finish. I just started talking with him last week. And today (about a week later the job is done. And done beautifully! Zach made an appointment for today for between 8 am-11am. Keith the service technician texted me when he was on his way. He was very nice and professional and did an amazing job!! He was done in about 1 hr. He even tightened a screw on one of my chair legs that had loosened. All in all a great experience!! I would definitely recommend them to anyone needed something done! And I would use them again!"

"I contacted Doorbusters Lock & Key for rekeying several locks at my home, and they were excellent from start to finish. The technician arrived quickly, was professional and polite, and rekeyed everything perfectly. All the locks work smoothly, and the price was fair and exactly as quoted. I really appreciate how efficient and honest they were, definitely a company I’ll call again for any locksmith needs. Highly recommended!"

Locksmiths questions, 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.

Changing door locks is a task that most homeowners can accomplish on their own. Standard door knobs are quite straightforward, and even more advanced locks, like electronic or smart locks, generally come with instructions. That said, the process can be time-consuming, especially if you plan to replace multiple locks around the house. It’s also a task that you want to complete correctly, considering that it affects the security of your house. That’s why hiring a pro is often best when changing your door locks.

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.

Yes. Most deadbolts purchased from a home improvement store include a step-by-step installation template that is easy to follow, even for novice DIYers. One of the most important steps for successful deadbolt installation is having the proper tools to start with and carefully measuring prior to any attempts at installation.

If your door handle turns without opening, the most likely culprit is a loose or stripped spindle. This part connects the handles to the latch mechanism, and when it’s not properly engaged, turning the handle does nothing. Other issues might include a broken latch, loose screws, or even something small blocking an inner mechanism. In any case, it’s usually a matter of tightening, adjusting, or replacing a worn-out part inside the handle assembly—or calling in a professional to do it for you.
