"ADT is the best company 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."

"Jeremy was punctual and professional. The appointment was easy to make with fast scheduling. I received an in-depth presentation and walk through of my home. He was very responsive to my questions and family's needs. There was no pressure to buy or add equipment I did not want or need. My new system was installed two days later. Larry the technical adviser was amazing. He was knowledgeable and friendly. He installed my system with no problems. He took the time to give us a lesson on how to use the app and new system. A few days later I had a question and he responded right away. I loved the system so much, that I referred my mother. Her system was installed a week later. I feel so protected knowing my family is safe using 1st Security Alarm company. I have the confidence of knowing that I can upgrade my system at any time. I can not thank Jeremy and Larry enough."

Locksmiths questions, answered by experts

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.

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

Lubricating a door lock is an important part of door lock maintenance. It involves taking the lubricant of your choice (it’s best to use whatever the lock’s manufacturer suggests) and spraying it directly into the keyway. Push and pull your key in and out of the lock to make sure it’s all the way in. 

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

There are several situations when you should change or replace your locks to ensure your home's security. Key moments include moving into a new house, after a break-in or attempted break-in, or when a roommate or anyone else with a key moves out. It is also wise to change your locks if you lose your keys, especially if they have an address attached or you suspect they were stolen. Finally, if your locks are old, broken, worn out, or have become unreliable, they should be replaced.
