Remote locking by Steffan

I am trying to solve a problem with my remote locking: neither key will unlock or lock the car remotely. They both stopped working around the same time – I can’t be 100% sure but I believe at the same time.

I have already tried and checked the following:

1. new batteries in both keyfobs

2. reset both keyfobs by pressing the lock button 5 times

3. checked that the central locking button locks and unlocks all doors

4. the battery was a bit low (it has sometimes been flat in the past as the car is more for looking at these days!) so I put it on the charger and now get a reading of 12.4V, which I would have thought would be adequate not to upset the more delicate electronics

5. battery reset

6. checked fuses 5 and 13 for the BCU (Body Control Unit)

7. the bonnet switch is ok as the horn gives the usual warning blast if the car is locked with the key with the bonnet opened

8. the fuel flap does not lock (but it is not expected to when the car is locked with the key)

9. the interior light comes on and goes off automatically as it should and the door open warning on the IPK (Instrument pack (IPK from the German)) works for all doors, bonnet and boot

10. it is not caused by RF interference because it’s parked in the same place it always has been, it happens everywhere and is not intermittent

So I'm now at a bit of a loss. Any thoughts gratefully received.

Receiver is probably knackered. They are plug n play so easily replaced. Either behind the dash or down by the center console.

Pleased to say that the new receiver (part number YWY000080 £32 from ebay) was a 100% cure. 15 minutes to fit without even unplugging the IPK.
