"Grant responded in minutes to my request for a quote to cut a new key and program a new Fob for my Ram truck. He arrived on time and finished the job in less than 30 minutes. He was polite, professional, and prepared to answer all my questions. The rate was reasonable, too. I highly recommend this business."

"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."

"I had a bit of trouble with my molding around the doors vs how the system was designed. The tech guy hung with me for 39 minutes until it was perfect. I called customer service a couple times after that with questions that came up. The customer service team are professional and knowledgeable."

Locksmiths FAQs, answered by experts

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

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.

Security systems are one of the measures that deter burglars the most. Research suggests most burglars look for signs of a security system before going in, although the presence of a security system doesn’t automatically mean they won’t enter the home. However, a security system with cameras can decrease the chance of a burglary overall.

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.
