i have swapped my worn key for a fancy yellow one to match the colour of the car.

i have swapped the immobiliser chip, the wee green board in behind the buttons, the battery and the key blade

the car will unlock or lock once then the led light flashes continually, i can unlock/lock the car manually in the door lock and turn the car on but it just won't unlock/lock the car

all the usual methods used from searching through this forum have not worked.

can get the car to unlock/lock from the fob fine for about a minute then the light just starts flashing again.

any help would be greats thanks
