- Brand: LockCar
- Model: CAN-IMMO
- Category: PIN to START Engine Car Immobilisers
Key cloning and OBD key programming are now among the fastest ways to steal a modern car. A CAN bus immobiliser adds an independent layer of security outside the factory system, so a copied or newly programmed key alone is not enough to start the engine.
- Concealed CAN bus immobiliser, with no LED, no keypad and no extra ECU visible on a diagnostic scan
- Your personal PIN on the factory steering wheel buttons, a Bluetooth tag, a smart watch or a smart ring releases the engine
- Stop keyless theft by relay attack and key cloning, the most common methods used in the UK
- Ultra-low current draw during operation, with shutdown available when the vehicle is off
- Installed over the CAN network and fully reversible, so no factory wiring is cut and the warranty stays safe
Compatibility comes first
To stop keyless theft on your car, the immobiliser must first be confirmed as compatible with it. Send us your registration plate number to start the check.
More ways to stop keyless theft
Stop key cloning with a PIN on the buttons you already have
No additional keypad is installed. The disarm PIN is entered on the steering wheel or console buttons your car already has, so a thief looking inside sees a normal cabin. The code is yours, it works offline and it is independent of any phone, signal or battery.
- PIN entered on existing buttons, dashboard left as standard
- No mobile signal or app needed
- Swap to a new PIN whenever you wish
- Valet mode for service and repair visits
Enter your PIN before every start to stop keyless theft
With a PIN code car immobiliser, starting the car gains one quick step. Sit in, enter your sequence on the original steering wheel buttons and the engine is ready. To an observer it looks like a volume change or a menu scroll. Without the sequence the engine stays blocked, even when thieves are already inside with a relayed or cloned key.
- Nothing added to the cabin. No keypad, fob or screen, so the interior remains factory standard.
- No giveaways. No LEDs, no beeps and no visible components.
- Copied keys fail. A cloned or boosted key may open the doors but will not start the engine without your code.
- Your code alone. The PIN sequence is personal, never a generic factory code.
- Quick and easy. It adds only a few seconds to your routine.
How a PIN code immobiliser stops relay attack and key cloning
Keyless ignition lets thieves intercept and clone your key signal, and newly programmed keys are another risk. LockCar CAN-IMMO keeps the engine blocked in both cases.
- Hidden and connected to the car’s CAN bus, outside the factory system
- Blocks any engine start that has not been authorised
- Needs the PIN sequence before the engine is allowed to start
- Triggers the car alarm if the PIN is missing 30 seconds after ignition on
Hands-free disarm with tag, smart watch or smart ring
A paired Bluetooth tag, smart watch or smart ring lets the car recognise you as you approach. The immobiliser releases within your set range and re-arms when you walk away, so the extra protection does not change how the car feels day to day.
- Automatic release distance adjustable from 1 to 5 metres
- Tag can be switched off before you lend the car
- Phone acts as master control, never as an automatic key
- Who can start the car is set in the app

Keyless theft protection FAQ
Can a PIN code immobiliser void my car’s warranty?
No. It is fitted through the vehicle CAN data network without cutting or altering critical factory wiring. The work is non-invasive and fully reversible, so the manufacturer warranty should not be affected.
Will it drain the car battery while parked?
Once you switch the vehicle off, the immobiliser shuts down. It only operates while the car is awake.
Can thieves who clone keys also find the immobiliser?
It shows no indicators, sends no RF signal and adds no ECU to a routine diagnostic scan, and each unit is hidden in a different place. With no standard fitting point, finding the block in the time a thief has is impractical.
What happens if my phone battery dies?
Nothing changes, as the car never depends on the phone. Use your PIN sequence on the original buttons, completely offline, or let the paired tag release it automatically.
