"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."

"Torin and Jack were so easy to work with, and they did an excellent job with our basement. It?s clear that Torin is very passionate about his company and the work that they do. We had to re-finish our basement after a pipe burst, and Torin made it easy to meet the requirements of our insurance agency. He provided all of the paperwork we needed in a timely manner, and was able to recreate our previous setup to the satisfaction of the insurance company. We also appreciated Torin and Jack?s flexibility with our schedule. They were very communicative and always let us know when they had openings ahead of our scheduled sessions so that we could continue to make progress on the build. We felt very comfortable with them in our home so often had them come while we were at work. Torin was very easy to work with and we highly recommend his company and will be using them again for future projects. Bonus - Torin and Jack both like dogs, and were super sweet to our pup! She loved having them"

Locksmiths FAQs, answered by experts

Rekeying door locks yourself costs a fraction of what you would expect to pay a locksmith. On average, it costs between $50 to $100 to hire a local locksmith to rekey your house, though labor costs may vary based on where you live. For a DIY solution, you can expect to spend $11 to $25 on a rekeying kit.

Yes, many locksmiths offer 24/7 emergency services for business lockouts, broken keys, and security breaches.

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. 

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

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.
