Customers say: Super punctual

"I would absolutely hire them if I had to do it all over again. Very understanding and very knowledgeable with extremely competitive pricing. They use excellent equipment! They were very prompt and a pleasure to work with. The installation was seamless for the alarm system and for the camera surveillance system. They finished the entire job for both systems in a big home within a couple of days. Very pleased with the entire team. Hire them! Description of work should be: installed 5 4K cameras and ran and hid wiring around home. Also installed brand new security alarm system with CO. Fire. Burglar"

"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

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

First thing first: Make sure you’re using the right key. If it’s the correct key for your lock, there are a few reasons why it may not be working, like the key is worn out or the lock is jammed. Try lubricating the lock and pushing the door closed to ensure the mechanisms work correctly. If you’re still locked out, call in for help.

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 easiest way to pick a lock is by using a titanium rake pick. This type of lock pick comes in a variety of shapes used to simulate different key configurations but generally has a tip with a bent design. Rake picks are the most beginner-friendly lockpicks and the simplest to learn how to use.

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
