"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."

"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."

"Barry from Mr. Handyman was fabulous! We purchased four hours and he did twice the work we expected to accomplish with that time! All the work accomplished was very high quality. Will definitely be back to Mr. Handyman the next time we need service, and will be asking for Barry!"

"Our dealings with Protect Your Home/ADT were delightful. We received a call back very fast after requesting a quote through Angie's List. We were able to complete everything on the phone; there was no paperwork or downtime. I had to call Customer Service with a question about the keypad, and they ended up telling me other helpful details on top of my original question."

Locksmiths questions, answered by experts

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.

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.

Begin by checking the power source, typically a battery or wired connection. Ensure the battery is installed correctly, has sufficient charge, and isn't corroded. If it's a wired lock, examine the electrical connections to confirm they are secure and free from damage. Additionally, inspect the lock's programming or settings. Confirm that user codes or access credentials are programmed correctly and that any remote control devices are paired and functional.

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.

Yes, you should change the locks as soon as you can after completing the purchase of a house. This is a matter of privacy and security, as you have no idea how many copies of the keys the previous owner made. You can change the locks yourself or hire a pro to replace or rekey the lock, which costs $50 to $100.
