"The locksmith was terrific. He was very knowledgeable and could give his professional opinion and sound advice, which was welcomed. He was not pushy about his advice, but we accepted it and moved forward with his recommendations. I would recommend him to my family and friends and call him back for my future locksmith needs."

"They got my sliding door and lock to work after a previous locksmith told me the door would have to come off and that the lock needed replacement. It was a matter of a few adjustments, so I think their understanding of locks and sliding doors together really helps."

"I found Handyman and Mrs. Helper on Angie’s List a couple of years ago. I have hired them multiple times to do electrical, carpentry, and painting work. Anne and Andy in the office are a pleasure to deal with. I normally have Steve or Heath doing the work in my home and they are both very skilled, conscientious, and patient. I highly recommend them."

Locksmiths questions, answered by experts

Many local hardware stores have the equipment to copy basic keys at a low cost. Some locations may have freestanding machines where you can pick out a blank and insert it and your original key into the duplicating machine.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to. 

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

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.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.
