Immobiliser & ECU Replacement Enquiries
An immobiliser-related starting problem needs a clear account of the vehicle's history and symptoms. If you reached this page while researching immobiliser defeat, contact GAD Tuning to discuss the underlying issue and the vehicle's ownership and repair context.
Identify the problem before choosing a solution
Tell us whether the vehicle has stopped starting, has had an ECU replaced or has recently undergone electrical work. Include any diagnostic messages and the identification of the original and replacement parts where known. A non-starting vehicle should not automatically be assumed to need a change to its immobiliser software.
The relationship between the vehicle's modules, keys and replacement components needs to be understood for the specific application. This page does not provide bypass instructions or advertise an unrestricted immobiliser-disable service.
Arrange an informed enquiry
Please provide the vehicle details, postcode, proof-of-ownership context and the work already attempted. GAD Tuning can discuss whether the enquiry is within scope and what information is needed next. The appropriate setting for any diagnostic or programming work will be confirmed individually.
