"I highly recommend hiring Sal The Door Guy of LI. Sal did an exceptional job installing our front door. He was highly professional, punctual, and demonstrated great attention to detail throughout the process. Since the installation, we have received numerous compliments on the door, and both my husband and I are absolutely thrilled with the result. We are incredibly happy we trusted The Door Guy of LI with this project."

"I was extremely happy with Hank the owner of Standguard Security Inc. I called Hank early in the day for information about an alarm system and he promptly came to my house that same day in the evening for an estimate and other options that he presented to me for my needs. I called him back and we set a time for the installation of a new system that was free ( just needed to sign up for a monitoring service). The day of installation Hank showed up with his tech guy Chris and promptly started to get to work. Chris the tech guy / installer was great and made sure everything was working correctly and answered all of my questions before leaving. They both were professional and I am very happy with the whole process."

"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."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

Locksmiths questions, answered by experts

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.

Most jobs take 30 minutes to 2 hours, but high-security systems or multiple lock installations may require additional time.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

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.

Costs depend on lock type, service complexity, labor, emergency availability, and whether security system integration is needed.
