"Hank and his son Ian were great! I called them in the morning and they came same day in the afternoon. provided me with a quote right away on the spot. Told them we could do it and they were here 5 days later putting new sensors in every window and door and also adding 3 smoke detectors and 2 carbon monoxide detectors. Highly recommend them!"

"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

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 And like all electronic devices, outdated models are more prone to problems and safety concerns.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.

If you’re having an issue turning the key inside a lock, chances are there is dust or dirt buildup within the cylinder. The easiest solution is applying a dry lubricant to the lock, which loosens the dirt buildup. You may need to turn the key a few times for it to work properly again.

Commercial locksmith services range from $75 to $500, depending on the job's complexity, such as key duplication, lock installation, or access control system setup.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

It’s possible, but depends on the design of your lock. Some door locks that lack a keyhole do boast a small hole on the exterior handle or knob. This hole’s primary function is to allow water to drain out of the lock, in addition to giving homeowners an easy spot to insert lubrication. However, you can typically use a paperclip in this pinhole to unlock the door by manipulating the mechanism inside.
