850 Immobiliser not turning off
In a fit of kindness I lent my battery to a stranded damsel in distress. Got it back fine but when I reinstalled it the immobiliser was engaged. All well and good but the remote hasn't worked ever. New battery in unit tried etc. The remote is the one in the picture that comes up nowhere in searches for a 1995 850 remote. Any and all ideas gratefully accepted.
I have tried removing fuses 6 and 15 as suggested elsewhere. And manually locking and unlocking the doors does nothing. The system warning light in on the dash near the ignition switch. Not on top of the dash as shown in many YouTube videos.
the car has been off the road with a non-start issue and is has driven me to the point off wanting to just set fire to it and walk away.
