"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."

"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

Typically, it can take around 15 minutes to rekey a lock. The time depends on the type of lock and how skilled you are at rekeying. The first time you rekey a lock, it may take a little longer. Once you get the hang of the process, it will move along much more quickly.

There are several ways to add security to a sliding glass door. To start, install a rod or deadbolt lock instead of the flip-lock that comes standard with most sliding glass doors. Add a sensor to the door and monitor any activity through your home security system.

Finally, installing shatterproof window film will help keep the structural integrity of the glass if it cracks.

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.

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.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.
