"I saw Gerry's reviews online and needed help with both installing a scmartlock, but also assisting in fixing the rent strike plate opening to allow the smart lock to close easily. I initially sent a message on Angie's list messaging and he quickly responded. He was good about responding through this means in a very timely manner. The day of the appointment he texted me with and ETA. After explaining the issue with the door and the deadbolt having trouble closing (unless you pull the door in slightly) and giving him the new smart lock, he began work. He was focused and did a great job. I would hire him again if I needed locksmith type work done."

"Highly recommend Nahoom. Punctual, honest, reliable and most of all, he takes time to explain everything from start to finish. In my case, the job I hired him for turned out to be time consuming and extremely cumbersome to accomplish. He never shied away from it and tacked it with no hesitation. He had to reconfigure an existing hurricane door lock and handle. This door is made of aluminum and metal. He made sure it was done 100% right. I will definitely be using Nahoom for future jobs. So glad I found such a detailed and reliable pro. Five star +++++"

"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."

"ADT is the best company to talk to in terms of security alarm. Being a locksmith myself I know how important it is to deal with the right people. I referred a lot of customers to them and so far they are happy with their service. I myself got one for my house. Thank you for a consistent service and great deal."

"CSI Secure Solutions was absolutely amazing.  I requested their assistance on a Saturday morning, expecting to get a call or email back on the next business day.  Chris called me Saturday morning to start the work.  Emails continued throughout the weekend as we fine-tuned the search criteria and information available.  By noon Monday, they had found my missing person and emailed me a detailed report.  In addition to the success of the search, though, I want to add that Chris was a real professional.  He was supportive and empathetic while being creative and diligent in the search.  I cannot say enough good things about Chris and CSI Secure Solutions.

Locksmiths FAQs, answered by experts

Yes, as long as it’s thick enough for the deadbolt. Most interior hollow core doors are at least 1 1/2-inches thick, which is usually the minimum requirement for a deadbolt. You’ll want to find the lock block first before installing. Also, most hollow doors require additional reinforcement for locks, such as a reinforcement plate or plywood block.

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.

As with any computer, smart locks can be hacked by someone with the technical skills to do so, but most people do not have that ability, making smart locks relatively safe. If you have any concerns about a compromised smart lock, opt for an encrypted smart lock, change your Wi-Fi password, and make sure that you only give out your password to trusted family and friends.

If part of the key is protruding out of the lock, you can use a pair of needle-nosed pliers or tweezers to gently turn the key in the lock to open the door. If the key is fully inserted into the lock, you may also be able to use a key extractor to help turn the key into the unlocked position. 

But if the key breaks off halfway into the lock or you simply can’t reach it to help engage the unlocking mechanisms, you should probably call a professional.

There are many types of deadbolts, but these tips work on most. First, address any grime buildup. A bit of WD-40 will loose up rust and dirt so the deadbolt can turn. Inspect the door and frame alignment if this doesn't resolve the issue. Adjust the strike plate or the deadbolt's position to improve alignment. If the problem persists, disassemble the lock to inspect for damaged or worn parts. If you are unsure how to do it, hire a local locksmith.
