Hello and welcome to
A scan tool will be needed to clear the Engine Control Module memory. We can disconnect the negative battery terminal cable for 10 minutes which clears the keep alive memory for the throttle and fueling adaptions.
To program the remotes there is a manual procedure that works most of the time.
1: Insert key into ignition
2: Pull the headlamp stalk towards the steering wheel.
3: While holding the headlight stalk in the position above, turn the ignition to auxiliary.
4: With Ign in Aux, flash the headlights 5 times, an audible confirmation should be heard.
5: Press any button on the remote/s to be programmed.
6: After confirmation of the remotes programmed – switch off the ignition.
