"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."

"Really well; the company was able to wire everything as originally planned. The installation was completed in 2 days; we tested the system for 3 days, and we have had no trouble with it at all. The installation involved very little mess or inconvenience and we are delighted with the results. We would recommend L & R to anyone looking for a sophisticated security system that operates in an astonishingly simple way.

"J&j were so professional they listen to my needs for the security of my home. They suggested what might be the appropriate resolution they were responsive to my questions. I made a decision on what hardware to purchase hardware to purchase. They made an appointment to install. They were on time. They were clean about the work they did. They gave me full instructions on how to operate my security Smart Lock and how to teach people we would be using it in the future. I cannot say enough about the excellence of their work. I am so pleased that I found out I highly suggest that you check them out if you are looking for something in the security realm"

"Ted and his crew are extremely talented and reliable. I called him late in the season to remove an existing wood deck and steps and replace with composite decking and railing. He came out when he said he would. He completed the job very timely and efficient. They kept the work area clean waste all in a safe place. I was/am very pleased with the work done by Ted and his crew and would highly recommend them for remodel work."

Locksmiths FAQs, answered by experts

Many insurance providers offer policy discounts when adding security features to your home. The best way to find out if new locks will reduce your premium is to simply ask your agent.

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.

Yes, many locksmiths offer 24/7 emergency services for business lockouts, broken keys, and security breaches.

Expect to pay between $50 to $200 if you hire a locksmith to change your locks. That figure includes labor and the cost of basic hardware. The cost will naturally be higher if you plan to install more expensive locks, like smart locks, and if you need a lot of them.

Homeowners can save money by replacing locks themselves. A typical rekeying kit costs about $10 to $25. The only additional cost is purchasing new house keys, and those are no more than a few dollars per key. If you want to replace the locks on your own completely, the main cost is the price of the locks themselves. A standard knob-style lock starts around $25, while electronic locks and smart locks will run in the hundreds of dollars. The only additional tools you should need are a tape measure, screwdriver, and screws if they are not already provided.

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.
