I take it you mean when attempting to program the immobiliser chip, not the remote? I've done remote key coding before with success.the most common bollock-drop seems to be accidental erasing of the SKC when attempting to programme keys in, sliding the little bar from 1 to 0 and hey presto no starting![]()
When using the remote you return the saved value (normally 1 or 2) to 0 to clear all matched keys and then rematch them... from what you've said above... you don't do that when messing with the immo?
