Immobiliser (IMMO) Off
The immobiliser prevents the car from starting without the correct key. If you've replaced the ECU, lost keys, or have a fault, the car may not start.
Our Service
We disable the immobiliser function in the ECU, allowing the vehicle to start without needing the original key or immobiliser signal. This is especially useful for:
- ECU swaps
- Kit cars
- Motorsport vehicles
Frequently Asked Questions
This is commonly required if you are installing a used ECU from another vehicle, building a track car, or if your factory immobiliser has failed.
Yes, the factory immobiliser will no longer function. We recommend installing an aftermarket alarm or physical security device.
Most IMMO off procedures take 1-3 hours depending on the vehicle make and ECU type. Some older systems can be done faster, while newer encrypted ECUs may require bench work.
We can disable the immobiliser on a wide range of vehicles including BMW, Mercedes, VW, Audi, Ford, Vauxhall, Renault, Peugeot, and many Japanese and Korean makes. Contact us with your vehicle details for confirmation.
Yes, this is one of the most common reasons for IMMO off. When fitting a replacement ECU from another vehicle, the immobiliser codes won't match. Disabling the immobiliser allows the replacement ECU to start the engine immediately.
Absolutely. Track and race cars often run stripped-down wiring looms without the original key system. IMMO off allows the engine to start with a simple ignition switch, which is standard practice in motorsport builds.
Yes. We save a backup of the original ECU software before making changes. If the original key system is still intact, the immobiliser function can be restored at any time.
