"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."

I'm a handyman because I have skills and experience from home ownership, business, raising children, and being entrepreneurial. I have talents to share and also enjoy some additional income. \n\nFact is, I enjoy helping folks who otherwise might not have the time or skill to do some of these tasks themselves.

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 And like all electronic devices, outdated models are more prone to problems and safety concerns.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

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.

You might assume that having two locks on one door will offer more protection than only one lock, but there may not be an advantage. While there’s nothing wrong with having two locks if you feel it’s best for your living situation, rest assured having one high-quality deadbolt installed correctly will offer a high level of protection.

Whether or not keyless door locks are safe and trustworthy depends on the visibility of the programming code—and a trespasser’s determination. Even if you carefully guard entry and programming codes, those trying to break in may be able to crack open the lock’s faceplate with a screwdriver and change the codes. The same goes for manual models.

Some find smart locks the safest option because it’s harder to manipulate codes without access to your phone. But it’s possible to get hacked even then. Consider installing an extended security system, like door and window alarms or surveillance cameras, to enhance security. 

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to.
