I knew the battery in the my key fob was failing. This morning I had trouble unlocking the car and when I went to do the school run this afternoon it wouldn't at all. Popped into the hardware and grabbed some new batteries but now it won't start at all. I'm getting an engine-disabled, press remote or enter keycode. Unfortunately neither pressing the remote nor entering the EKA is working. I suspect the key's not synced and I'm going to double check the keycode with the dealer, though i'm pretty sure I've used the EKA in the past. Unlocking the driver's door with the key unlocks the bootlid, but nothing else.
I've had the door panel off and it appears that someone has replaced the original latch with the later style one with the extra harness (the car's an M-Reg so it should have the early latch).
There has been a "whirring" noise coming from the driver's latch for the past few weeks when I unlock on the remote.
I've got a multimeter and can test it but the car's parked on a busy road three miles from home so I didn't have time this evening. Before I start on that, any advice?
