I'll check out the transmitter. Above left knee, uk or us? Glove box is out anyway. So I'll give it a good look if it's not raining.

Yes tried the locks. Ordered a used lock to swap over, hoping that might do it.

Could be that even with battery off, the ecu remembers that the alarm was tripped and goes straight off. If so, then door lock switch not working would account for it. But I'd rather check it first than just replace.
