"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

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

Newer, electric-powered door locks generally have a life span of five years or less. That’s thanks, in large part, to a phenomenon called planned obsolescence, in which products are programmed to need replacing after a certain amount of time. That’s also why older, manual, push-key locksets can last up to 30 years with regular cleanings and maintenance. When it does come time for a new set-up, know that the cost to change locks ranges from $130 to $500 on average.

Always consider security a top priority in your home. Perform a safety inspection of your home. Look for broken locks and rusty deadbolts, and take an inventory of who has access to your keys.

Consider the locks on your shed, safe, and other household items. Professional locksmiths can help you determine the best safety and security options for your home and feel at ease.

When a locksmith comes to your home, ensure your safety by having the locksmith show identification and provide an itemized invoice that you can reference later.
