Your button sequence is your key. This anti theft car immobiliser lets you choose a personal combination of presses on buttons such as the window switches, steering wheel controls or centre console. Only the right sequence, in the right order, allows the engine to start, giving you a simple daily routine that a thief with a cloned key simply does not know.

- Your button sequence on the steering wheel releases the engine, or a Bluetooth tag, smart watch or smart ring does it for you
- Built to defeat relay attack and key cloning, the methods used in most UK keyless car thefts
- Very low power draw while active, with a shutdown option once the vehicle is switched off
- Fitted through the CAN network and fully reversible, with no factory wiring cut and your warranty left intact

A button sequence anti theft immobiliser on the controls you already use
Nothing is bolted to the dashboard. Your disarm sequence goes in through the original steering wheel or console buttons, so anyone peering through the window sees a normal interior. The combination belongs to you, works offline and never relies on a phone, a signal or a battery.
- Sequence entered on the original buttons, no extra hardware on show
- No mobile signal or app needed to drive away
- Your own combination, which you can change whenever you like
- Valet mode for servicing and garage visits
Press your button sequence, then start the engine
Using a button sequence immobiliser quickly becomes second nature. Sit down, press your personal combination on the factory steering wheel buttons and the engine is free to start. Anyone watching simply sees a driver turning up the volume or scrolling through a menu. Skip the sequence and the car stays immobilised, even when thieves have opened it with a relayed or cloned key.
- No keypad, fob or screen to fit. The cabin stays exactly as the factory built it.
- Silent and invisible. No lights, no beeps and no parts reveal the immobiliser.
- Relay and cloning attacks stop at the doors. A boosted or copied key signal cannot start the engine without your sequence.
- Personal to you. The sequence is your own, never a shared factory default.
- A few seconds per journey. Entering it soon feels like part of getting in the car.
How a button sequence stops relay attack theft
Keyless ignition is convenient, but it lets thieves capture and copy the signal from your key. With LockCar CAN-IMMO fitted, that copied signal is not enough to start the engine.
- The immobiliser sits hidden on the car’s CAN bus
- Any start attempt made without authorisation is blocked
- The engine runs only once the driver has entered the correct button sequence
- If no sequence is entered within 30 seconds of ignition on, the car’s alarm is triggered
Skip the sequence with a tag, smart watch or smart ring
Pair a Bluetooth tag, smart watch or smart ring and the car knows it is you as you approach. The immobiliser unlocks within the distance you choose and re-arms as you walk off, so everyday driving feels just like it did before.
- Hands-free disarm range adjustable between 1 and 5 metres
- Physical off switch on the tag for when you hand the keys over
- Your phone remains the master control and never acts as an automatic key
- Every authorisation managed from the app

Anti theft immobiliser questions
Does fitting an anti theft immobiliser affect my car’s warranty?
It should not. Installation is done through the vehicle’s CAN data network, with no cutting or altering of critical factory wiring. Because the fitting is non-invasive and can be fully reversed, the manufacturer warranty should remain unaffected.
Can the immobiliser flatten my battery?
It is designed not to. The immobiliser only runs while the car is awake, and when the vehicle is switched off it shuts down.
Could a thief locate the immobiliser and get around it?
It gives nothing away: no indicator lights, no RF signal and no additional ECU on a routine diagnostic scan. Each unit is hidden in a different spot, so there is no standard place to search, and finding it in the time a thief has is impractical.
What if my phone battery is flat or I have no signal?
Your phone is never needed to drive. Enter your button sequence on the original controls, fully offline, or let the paired tag release the car automatically.
