"We had an exterior door to our garage that would not close/latch properly and therefore presented a security risk. I called multiple companies for quotes and explained we'd like to try repairing the door first, but are open to replacing it if necessary. Multiple other companies told us there was no other option but to replace the door. Robert's company was the last one on our list to gather a quote from. He came by the very next day after I called, immediately found core problem with the door (simple loose screws in the hinges) and fixed then and there. The fix was so simple, he didn't even charge us. I so appreciate that Robert wasn't trying to scam us into a bigger more expensive project of replacing the entire door. He is honest and quickly finds the root of the problem. We will be hiring Robert's company exclusively moving forward for our various projects around the house. Feeling so lucky to have found him! Thanks so much, Robert!"

"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."

"From the moment they first contacted me to the moment Gary left our house, dealing with Handyman Pros was a delight. The price was certainly reasonable and the work was done within a few days of posting the Angi request. Gary was certainly knowledgeable and worked fast. He rehung a closet door and I marvel every time I open it now how smoothly it operates. I have no doubt I will be using their services again."

"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

"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."

Locksmiths questions, answered by experts

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.

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

It can affect security, especially if you don’t finish it properly. A Dutch door has more moving parts that can be compromised, so you’ll want to use solid hardware and make sure everything lines up and locks cleanly. If the latch is flimsy or the two halves don’t sit tight, it’s going to be easier to force open.

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.

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.
