"I was very impressed with Bob. He came out at the time that he said he would be here and worked very quickly and efficiently. To top it all off, his prices are the best that I have ever seen for a locksmith service. Bob was very personable and also gave me some great tips about how to make my home more secure. I have several other rental properties and I will for sure be using his services in the future. I highly recommend  this locksmith for anybody out there."

"The job was good and there were no problems. I originally wanted new keys made for my exisiting lock but was told that they could not do that.  So a new lock was isntalled instead.  Although the work was good and the locksmith was courteous and professional, I just did not expect to pay that much to replace a lock.

Locksmiths questions, answered by experts

It’s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole’s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside. 

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

Proper door lock maintenance includes keeping the locking mechanism clean and clear of dirt, dust, and grime buildup, lubricating the lock annually, inspecting and tightening the lock regularly, and treating the door with care. If your maintenance reveals problems, it may be time to replace the lock or have a professional inspect it.

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.

A door lock service is performed by a professional locksmith, and the cost of hiring a locksmith for these kinds of repair tasks usually runs in the $100 to $250 range. It all depends on the type of locks you have, how many locks are included in the service, and where your home is located. Always choose reliable, trustworthy locksmiths, and get a few quotes before making your choice.
