Symptoms of a failing CAS immobiliser module (66126954717)
It authorises the key and allows the engine to start. When it fails, the car will not recognise the key, does not crank, or shows a drive-away immobiliser fault. Fitting a matching original unit restores correct operation without changing the wiring.
