I have a 1995 Toyota Landcruiser 4.5 VX Petrol Auto.
This morning I changed the battery and now the immobiliser won't let go. Neither will the central locking work via the remote (it still works via the key). It's the standard factory fit immobiliser.
If I try to start it the ignition lights all come on but it won't turn over; however, if I leave the key in the "ign" position, disconnect and then reconnect the battery I can then start it and it runs fine. Once I switch off however I'm back to square one.
Does anyone have any idea what might be wrong?, and more importantly a fix?
