"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."

"When I called around for quotes and to make the appointment, AA Key & Lock had clear upfront pricing and answered all of my questions. They had several options to find a convenient time for the service. They were able to rekey front and back door and install deadbolt on basement door for a newly purchased home in about an hour."

Locksmiths FAQs, answered by experts

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

If you also have a standard door leading to your garage, install a robust deadbolt lock and reinforce the frame with security plates. Then, secure any windows with shatterproof glass or film to deter break-ins. Consider a smart garage door opener for your car entrance, enabling remote monitoring and control through your smartphone. Motion-activated lighting around the garage to deter intruders is a great way to amplify these security efforts. Lastly, educate your family on security practices, such as keeping the garage entrances closed and locked.

Locksmiths recommend changing your locks once every seven years for the best security at your home. Locks can wear out over time, so you should inspect your locks regularly. A higher grade lock provides you with more cycles than those with a lower grade.

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.

You can cut a door knob off using a sawzall, but you risk causing additional damage to the door itself. You’ll also need to completely replace the door knob, costing you extra money and another trip to the hardware store.
