We build the lock thieves can’t pick.
UK-engineered vehicle security, designed and built by us from scratch. We fit every device ourselves, at your door, anywhere in the UK.
We started because we knew we could build something better.
LockCar was founded by Victor, a hardware and software engineer based in the UK. He designed the circuit boards, wrote the firmware, built the app, and assembles every device himself. Nothing is imported. Nothing is rebranded. Every component was chosen by the same person who will come to your door and fit it.
The idea came from a simple observation. The market was selling immobilisers for £500 that connected directly to the car’s ECU network, the electronic brain that runs everything from your engine to your dashboard. That connection was causing problems: diagnostic errors, warning lights, and in some cases cars that would not start. We knew there was a better way.
“We wanted to build something that actually works, installed properly, by someone who built it. No installer to find. No manufacturer to chase. Just one point of contact, end to end.”
So we built a relay-based system that physically cuts the engine circuit without touching the vehicle’s electronics at all. No CAN bus interference. No ECU errors. No comebacks. Just a device that does exactly what it promises.
There is nothing else quite like this in the UK market.
Every competitor either sells a product and leaves you to find an installer, or uses CAN bus technology that carries real risk to your car’s electronics. We do neither.
We design and build everything ourselves
The circuit board, the relay, the firmware, and the app. All created from scratch in the UK. Not imported. Not assembled from off-the-shelf parts. Built by an engineer who understands every component.
We never touch your car’s electronics
Our system is relay-based, which means it cuts the engine circuit physically, completely separate from the CAN bus network. No data connection to your ECU. No risk of dashboard errors, limp mode, or diagnostic faults.
We build it and we fit it
The same person who designed your device comes to your door and installs it. There is no middleman. If you ever have a question or a problem, you call us directly. One number, one person, end to end.
No PIN codes or button sequences
Our proximity TAG fob disarms the system automatically as you approach. You just walk up and get in. No button presses, no codes to remember, and no risk of locking yourself out of your own car.
Full app control from anywhere
Our ONE Plus gives you live camera, real-time GPS, remote engine cut, and automatic night immobilisation, all from your phone. Fleet-grade capability at a personal price point.
Nine products, one manufacturer
From a £49 dealer add-on to a full 4G fleet system, everything comes from us. One relationship, one training session, one contact for support. Compatible with any 12V or 24V vehicle.
Simple from start to finish.
Most customers go from first message to fully fitted in a single day. Here is exactly what that looks like.
You get in touch
WhatsApp or the quiz. Tell us your car and your location. That is all we need.
We give you a quote
You hear back from the engineer directly. No call centres, no wait times.
We come to you
At your home, your workplace, or anywhere that suits you across the UK.
We fit it in under an hour
App set up, TAG fob paired, everything tested before we leave.
We are always reachable
One number. The person who built and fitted your device.
“We are not a marketing company that sells security products. We are engineers who build them. When we come to your door, we know exactly what we are fitting because we made every part of it. That accountability does not exist anywhere else at this price.”
Nine products. One manufacturer. Every vehicle covered.
From a straightforward entry-level immobiliser to a full 4G remote system with live camera and GPS, everything is designed and built by us. All products work on any 12V or 24V vehicle, including cars, vans, HGVs, EVs, and motorhomes.

Three things we will never compromise on.
-
Honesty about what our products do. We will never claim our system stops every possible theft method. What we will say is this: it physically prevents relay attacks, the most common form of modern car theft, and it does so without any risk to your car’s electronics. That is what matters.
-
One point of contact, always. When something matters, you should be able to speak to the person who is responsible. We will never hide behind a support ticket or a phone menu. The engineer who built your device is the person you call.
-
Products that do not damage your car. We made a deliberate choice to build relay-based systems rather than CAN bus devices. That choice costs us more in engineering time. But it means we can look every customer in the eye and say: this will not cause problems with your car’s electronics. That matters more than the margin.
