hi, we have a ten year old corolla. it is fitted with an immobiliser with a very fiddly key that doesnt turn just lifts up or down.
its easier on short stops to leave the ignition switched on, so we dont have to fiddle with this key.
i remember being told many years ago that to leave the ignition turned on (without the engine running) was to risk burning out the coil. this was some forty years ago but does this advice still apply? thanks for any advice john west
