Car wont recognise key code on all keys.
the key code light stays onthe red key code can not be lost, it is permanetly stored in the code box.
if we assume the problem is actually because the immob cant recognise the key codes, and you have the red key, and that is actually your red key (has it worked before?), then we can also assume the problem must be either a wiring fault in the immob circuit, or a component fault. that means you either have a faulty earial around the ignition switch, a faulty code box, a faulty ecu, or a wiring fault inbetween them.
i need to know how you know the immob wont recognise key codes? is that the finding of a diagnostic check, or do you have the key code light remaining on, or have you guessed that is the problem?
