I’m looking for technical help or recommendations on: immobiliser.
Opened the drivers door with a battery dead key fob. Alarm went off. Disconnected batter to stop it. Reconnected battery. Now the car won’t start. Central locking still works. Convertible roof lowers and raises. All the usual icons appear on the ignition when key is turned to on but no sound. Help please.
The usual procedure if you locked/alarmed the car with the fob but unlocked it with the key is to put the key in the ignition and turn on, this stops the alarm.
I would check your fuses, maybe blown one disconnecting the battery, particularly the ignition one.
