"Rick is a master locksmith who has serviced my home for re-keying and installing locks and knobs on the doors of my house, right after I bought it last year. This time he came out and installed a new cylinder on my garage door lock. He also secured the turn mechanism by replacing missing screws. Finally, he cut down a stubborn and dangerous metal anchor for a defunct clothesline in my backyard. His work is always excellent and his prices are fair. He has a mobile shop, so all work is done while you wait and onsite. Can't recommend Rick and the Keyhole enough. Five stars."

"It went well. The locksmith arrived on time, was respectful, and showed expertise in the job. He made some helpful suggestions that simplified the work. I would recommend this firm for locksmith services and I would consider using them for handyman services."

"Eli arrived punctually after calling to alert me of his arrival. Once here, after hearing the problem, he looked at the door and realized the problem was that the door had settled low. I didn't need new locks, as I had thought; instead, he simply fixed the door so the locks fit correctly again. Instead of having to pay for new hardware, I was only charged for the visit and 15 minutes of time."

"I could not be happier with my experience this past Saturday with Raanan the Locksmith (and his wife Hanna). My husband and I had just arrived at our hotel, and somehow managed to lock our car keys inside the car while unloading it in the hotel garage. We were preparing for a long evening searching for a locksmith that could commit to helping us the same day. I received several texts and phone calls in reference to our need to hire a locksmith but chose to hire Raanan after my initial conversation with his wife. She seemed genuinely interested in helping us with our dilemma. My phone calls and texts re-confirming that they were actually coming to unlock the car, were answered promptly and we were kept informed about their arrival time. Raanan and his wife were professional and very pleasant to work with. Our car was unlocked quickly, and we still had time to keep our dinner reservation. We highly recommend Raanan the Locksmith for anyone needing help unlocking their car!"

"I called Alarm Protection Group AFTER my office was burglarized. Now I feel SAFE. William is great to work with. He's neat and tidy, prompt, presentable - not a butt-crack type of guy, and he doesn't leave a mess in his wake. He's also knowledgeable about the equipment and only uses high-quality products."

Locksmiths questions, answered by experts

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.

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.

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.

Security systems are one of the measures that deter burglars the most. Research suggests most burglars look for signs of a security system before going in, although the presence of a security system doesn’t automatically mean they won’t enter the home. However, a security system with cameras can decrease the chance of a burglary overall.

Locksmiths offer keyless entry systems, high-security locks, panic bars, electronic access control, and biometric security solutions.
