"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."

"Im am very happy I found this company! Thanks Nick and Marshal for the outstanding work. Their quality/detail is unbeatable! They went above and beyond to meet my expectations. They had a tough job to fix a deck that someone else built so poorly. They explained what could be done, what could improve but also what couldnâ t be fixed entirely. The only thing was that my budged was tight, but I also requested other things outside the quote he gave me. The only thing I would do different next time was to purchase all the items in advance and ask them to install. That would create less trips for them to the store prior to initiate the service/project. Thanks Nick and Marshal with everything. I hope to hire you next time."

Locksmiths FAQs, answered by experts

Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.

When you take a key to a hardware store or a locksmith for copying, you can expect the key-cutting process to take as little as 30 seconds. The key copier will review your current key to decide on the correct blank. Then, your original key and the blank are inserted into a key duplication machine to cut an exact key copy. When it’s all said and done, you can have a new key in your hand in just a couple of minutes.

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.

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.
