"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 questions, answered by experts

It is best to use a dry lubricant, such as a Teflon-based option, for door locks. Unlike popular oil-based lubricants, dry lubricants leave a non-stick, water-repellent coating that does not attract dust, dirt, and other debris. Using an oil-based lubricant can cause these particles to build up inside the lock, making it difficult to operate or even damaging the internal mechanism. You can find dry lubricants, some of which are made specifically for locks, at most hardware stores.

Rekeying a lock changes the internal mechanism so that a new key works, while replacing a lock involves swapping out the entire hardware. Rekeying is a good, cost-effective option when you want to ensure old keys no longer work, such as after moving into a new home or losing a key. It's also ideal if you want to keep your existing lock hardware. You should opt to replace the locks entirely if you want to upgrade to a more secure or different style of lock, if the current lock is old or damaged, after a break-in, or if too many copies of the old key exist.

In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.

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.

Typically, it can take around 15 minutes to rekey a lock. The time depends on the type of lock and how skilled you are at rekeying. The first time you rekey a lock, it may take a little longer. Once you get the hang of the process, it will move along much more quickly.
