"Hire them! I can't explain how tedious this job was, my boss is not an easy person to work with and they made it seamless. They completed a massive job, in less than 3 days which included hardwiring camera's all over a massive property and a detached garage. They had excellent communication and were very easy to work with. I mean - the owner wanted one thing, then another, oh and another, oh wait this too. THEY DIDN'T BAT AN EYE. Do yourself a favor, hire them! They listen, they're honest and get the job done."

"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."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

Locksmiths FAQs, answered by experts

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.

The cost to hire a locksmith varies depending on the service you need. Consult your locksmith about the price of your requested services before hiring for your repair or installation. Some of the most common types of locksmith services include:

  • Installing deadbolts: $40–$75

  • Rekeying: $80–$160

  • Unlocking your house: $65–$180

  • Changing locks: $50–$200

  • Installing electronic locks: $50–$500

  • Installing smart locks: $200–$800

  • Keyless locks: $50–$300

Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.

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.

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.
