Customers say: Quick response

"Roy was a lifesaver! On a Saturday night I realized my house keys went missing and I got an almost immediate response when I reached out. I made an appointment with him for the morning and he called 15 min prior to tell me he was on his way. When he arrived he was a few minutes early. He had my condo door unlocked in less than 5 minutes and I thought what he charged me, for a house call on Easter Sunday, was very fair. I really appreciated how responsive and reliable Roy was. I will definitely recommend him next time someone I know needs a locksmith."

"Awesome Service! I hired recently to install two garage door openers. I am pleased with his service. I described him as a professional, punctual and knowledgeable. He knows what he is doing. He visited prior to start the project and described what will be needed to complete the project and show up exactly on time (sharp) and completed the job very neatly and professionally. The best part and extra mile he gave in the whole project was follow up after the job is complete which mostly no one does after receiving the payment. Thank you so much for the job."

Locksmiths FAQs, 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.

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 And like all electronic devices, outdated models are more prone to problems and safety concerns.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

Yes, locksmiths can design and install master key systems that grant different levels of access to various employees while maintaining overall security.

Door locks should be changed roughly every seven years. The average lifespan of a door lock is seven to 10 years, so it’s best to err on the side of caution and change them early, especially if they are showing signs of wear and tear. Examples of deterioration include visible rust and difficulty opening or closing the door. Some locks can work safely beyond 10 years, but it depends on how often they are used and whether they are exposed to damaging environmental conditions like precipitation or extreme temperatures.

You might want to change a door lock entry code for a handful of reasons. The most common answers are extra security or a forgotten code. You may also find yourself in a position where you need to temporarily change the code to allow a guest to come and go freely but want to switch it back once things return to normal.
