hi there i am after some advice on how to activate my immobiliser on my j reg valver.
when i turn the key in the glove box the immobiliser comes on. I am unable to start the car which i guess shows its working and the red light near the steering wheel starts flashing. HOWEVER
when i use the blip key to unlock the doors which should deactivate the immobiliser the red light stays on and the immobiliser is still on?????
do i need to disconnect the battery for a while although i did try this for about 5 minutes. should i disconnect the ecu???????
