Your Trusted Door Locksmith in New York City

Your home’s doors are the first line of defense against intruders.

Lock and Tech USA delivers comprehensive door lock services to homeowners throughout NYC and surrounding areas.

Expert Locksmith Door Repair for Every Situation

Door locks endure constant use and exposure to the elements. Over time, even the highest quality locks can develop problems. Keys may become difficult to turn, deadbolts may stick or fail to extend fully, and electronic locks may malfunction unexpectedly. When these issues arise, professional locksmith door repair restores your security and peace of mind without the expense of complete lock replacement.
Our technicians diagnose lock problems accurately and efficiently. Sometimes a lock simply needs cleaning, lubrication, and adjustment. Other times, worn internal components require replacement. In cases of damage from attempted break-ins or severe wear, full lock replacement may be the best solution. As your dedicated locksmith for house door repairs, we assess each situation honestly and recommend the most cost-effective solution.
Common door lock problems we repair include:
- Keys that stick, jam, or are difficult to turn in the lock
- Deadbolts that won’t extend or retract smoothly
- Loose or wobbly door handles and lock assemblies
- Misaligned strike plates causing door closure issues
- Frozen locks during winter months
- Electronic locks with battery or sensor failures
- Locks damaged by attempted forced entry
- Worn cylinders that no longer hold pins properly
- Broken key extraction from jammed locks
Don’t ignore door lock problems or postpone repairs. A malfunctioning lock compromises your home security and can leave you locked out at the worst possible time. Lock and Tech USA provides prompt locksmith door repair service that addresses issues before they become emergencies.
Fast Locksmith to Open House Door When You're Locked Out

Getting locked out of your home is one of the most common and frustrating household emergencies. It happens in an instant — you step outside to grab the mail, take out the trash, or check on something in the yard, and the door closes behind you with your keys still inside. When this happens, you need a locksmith to open house door quickly and without damaging your property.
Lock and Tech USA specializes in residential lockout assistance throughout New York City. Our locksmith door opener technicians use professional-grade tools and non-destructive entry techniques to regain access to your home safely. We understand that being locked out feels vulnerable and stressful, especially if children, pets, or valuables are inside. That’s why we prioritize fast response times and treat every lockout call with urgency.
Our locksmith for house door emergencies arrives prepared for any lock type you may have. Whether your home uses traditional pin tumbler locks, high-security cylinders, smart locks, or electronic keypad systems, we have the expertise to open them without causing damage.

Professional Locksmith for Home Door Security Enhancement

Installing the right locks on your home’s doors is one of the most important investments you can make in your family’s safety. But not all locks are created equal, and improper installation can undermine even the best hardware. As your expert locksmith for home doors, Lock and Tech USA provides professional lock installation that ensures maximum security and reliable performance.
We work with homeowners to assess their security needs and recommend appropriate solutions. Factors like door material, frame construction, neighborhood safety concerns, and personal preferences all influence which locks are best for your situation. Our technicians install everything from basic deadbolts to high-security locks, keyless entry systems, and smart locks that integrate with home automation platforms.
Beyond new installations, we help homeowners upgrade outdated or inadequate locks. Many older homes have locks that no longer meet modern security standards. Worn locks, outdated designs, and locks with compromised keys all present vulnerabilities. Our locksmith for home door upgrades can replace these weak points with modern, secure alternatives. We also offer rekeying services for homeowners who’ve recently moved, experienced a break-in, or simply want to ensure that old keys no longer work. Lock and Tech USA makes your home more secure, one door at a time.

I am a property manager in Manhattan and had to find a company to repair a busted intercom system. I came across Lock and Tech, and George set everything up for me, answered all of my questions over three different conversations, and he never made me feel like I was bothering him with all my questions and concerns. The technicians did a fabulous job and had the intercom fixed in less than an hour. The men cleaned up thoroughly after the job which I completely appreciated. I highly recommend this company and will definitely use them again.

We are renovating our small (6 unit) apartment building in Manhattan and decided it was time to replace our very old and finicky intercom. We opportunistically decided to install a Virtual Doorman so we buzz deliveries in when we are not at home. The team at Lock and Tech has been great. The installation was all done in one day and we all have electronic keyfobs that control our first two doors, in addition to the keypad. The team is very responsive and professional. I highly recommend them!

After doing research for a an installer, we landed with Lock & Tech for a small install. I was so impressed with their customer service, quality and overall work, we hired them for a larger job. We’ve like the work so much we’ve been using them for the past 3-4 years doing installs in and around our facility. The team is very knowledgeable and accommodating, and will work with you throughout the whole process until you are satisfied. Prices and services are great and will continue to use their services in the years to come. Highly recommend!

I selected Lock & Tech for our intercom system installation after looking up every company that does this work. Even after selecting them I was skeptical of Google and Yelp reviews and wasn’t sure what I would get. It turns out they are reliable, do expert work, and are great to work with. My building is very old and they did an excellent job of installing the intercom, strikers and locks despite the difficulties that exist in old buildings. They were attentive to all our particular needs and responded quickly to calls or texts. Above all, the price was very reasonable, more so than other installers. I highly recommend them.

We had Lock and Tech USA install a security camera system to our Prospect Heights co-op and Gabriel and his team did an amazing job! They installed the whole system, including 6 cameras on the interior and exterior of our building in one day! The quality of the cameras and equipment is top of the line- the picture is crystal clear. They are very thorough, responsive, professional and offer high quality installation and equipment for a great price. They email and call when you need and made sure we were 110% happy with everything. Highly highly recommend these guys!

Derek was amazing and professional. He met all my needs and answered all my questions. His workers came knowing what was needed to be done and did an amazing job. I needed to get my camera system replaced with a new one. They charge on a hourly basis, so the workers did not take their sweet time to run up the price. They did a very professional job at a very fast rate. I am very pleased with Lock and Tech USA. I will always refer to them for any security needs. Thank you guys.

Lock and Tech USA successfully installed an AIPHONE intercom system at my Brooklyn office. Their technician, Viktor, was personable, pleasant, and highly skilled. Viktor carefully installed the intercom system without damaging expensive suede wallpaper, professionally concealed wires in walls, and ensured that the intercom system was perfectly functioning before departing. Viktor is a wonderful technician. As such, I recommend Lock and Tech for AIPHONE intercom installations – Ask for Viktor!

Great communication, follow-up, and support!! Sales was straight forward, no point even negotiating, very reasonable and understanding! Installation was quick and thorough and they put everything exactly where I wanted them to be. We had an issue with one of the devices and they responded in minutes and even came back the next day. Amazing service!
