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

When the temps drop, sometimes you need to thaw a lock to regain access. Options include warming the key with warm water, applying a de-icing spray, or using a hair dryer on low heat. Avoid using boiling water to prevent damage. To prevent future freezing, consider installing a cover or shield over the lock to keep water and ice out. Remember to be patient and gentle during thawing to avoid damaging the lock or key. If all else fails, consult a professional locksmith.

If your key breaks in a lock, first remain calm and avoid forcing the broken piece further in. You may be able to remove it yourself if a portion of the key is still protruding from the lock. To aid removal, lubricate the keyhole with a graphite-based spray. Then, try using tools like pliers, tweezers, a bobby pin, or even a jigsaw blade to gently grasp and pull the broken piece out. If these methods don't work, you can't reach the key, or you're concerned about damaging the lock, it's best to call a professional locksmith for assistance.

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. 

Rekeying is typically cheaper than replacing locks. Professional rekeying costs between $40 and $160, sometimes with an additional fee of $15 to $40 per lock. A locksmith's hourly rate averages around $75. If you do it yourself, a rekeying kit can cost as little as $10. In contrast, replacing a lock costs between $130 and $500, with an average of around $315, depending on the hardware and lock type. Rekeying is a simpler process that changes the key for your existing lock without replacing the hardware. It is a good option if you have a quality lock that works well, you've recently moved, you've lost a key, or you need a quick security upgrade. The best choice depends on the condition of your current locks.

The good news is that, yes, you can change locks yourself. Many people find it’s an easy DIY project that requires few tools and not much expense (depending on which lock you’re installing). If you have trouble with any part of an installation, you can always call a locksmith to help finish installing them.
