The best service I received. Thank you for your patience and helping me out with my tough project. Thank you for working with me on the price as well. I will recommend to family and friends.
Lock and Tech delivers top-tier service. The team is professional, knowledgeable, and shows up ready to solve the problem—not experiment. Fast response times, clear explanations without tech jargon overload, and a genuine sense that they care about the client, not just the hardware.
The work was done efficiently and cleanly, using up-to-date technology that feels both secure and forward-thinking. If you’re looking for reliability, expertise, and real customer service (yes, it still exists), Lock and Tech is the right choice.
Hired this company to move our intercom system from inside to outside and also to install a new magnetic door lock on the outside glass door. This company did a great job and did a professional installation. They even helped us set up the AxTrax software for free to help manage access for our key-fob system. Recommended!!
Lock and tech provided a great price and service. They did our acces points, alarm and security cameras for the Doctors office. Highly recommend!
They have really good service for security cameras, access control and alarm. amazing person I feel like in they are best with cheap price.
Gabriel and his team installed a new intercom system in my building. They are so professional and responsive. They did the job quickly yet with precision. It is such an improvement from what we had, I can’t believe we waited so long to do it. I highly recommend Lock and Tech!
It was nice to have a professional company install my intercom system. Much better than these "save a dollar" places that don't have a store and make a mess. But this place has smart, nice people who are professional and know what they're doing. I highly recommend Lock and Tech!
Common questions
Frequently asked
Five answers we give most often. The rest, we'll cover in person.
We design, install, and service complete security systems: surveillance cameras, burglar and fire alarms, access control, intercom systems, and commercial locksmith services. We also handle low-voltage cabling, telecom, and audio/video installations. Every project is engineered as a single integrated system, so your cameras, alarms, and access control work together instead of side by side.
