"Grant responded in minutes to my request for a quote to cut a new key and program a new Fob for my Ram truck. He arrived on time and finished the job in less than 30 minutes. He was polite, professional, and prepared to answer all my questions. The rate was reasonable, too. I highly recommend this business."

"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!"

"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."

"We have had a malfunctioning mini split that we could not find a technician for, after multiple failed attempts. Vintage Home Services was prompt in responding and scheduling, diagnosed our issue, and repaired for a fair price. Would highly recommend."

"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!"

Locksmiths FAQs, answered by experts

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.

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.

Over time, latch components may wear out or get grimy, leading to this problem. First, check for dirt, dust, or debris in the latch mechanism to ensure smooth operation. Use an aerosol duster and lubricant to clean and loosen. You may also need to tighten the screws in the component, adjust the strike plate, or replace the lock. If none of these steps resolve the problem, consult a professional locksmith.

Most door knobs can be removed with a Phillips or flathead screwdriver. If you don’t have either of those available, a paper clip or small pin can sometimes work, but the extra effort may not be worth a quick trip to the hardware store.

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.
