Keyless entry problem diagnosis/fix
#12
UPDATED:

I located and unplugged the keyless antenna in the boot/trunk area and that caused a DTC to throw.  When I press the tailgate "close and lock button" nothing happens.  Previously (ie with the antenna plugged in) I would get a "can't find key" beep beep beep, now nothing.

So I have proved that missing/unplugged antennae do cause a DTC but that does not mean much.

The keyless lock/unlock still works sometimes,  maybe I should buy a new key and add it to the config to make sure it is not the existing keys failing. That said, I have 3 keys that fail. It still works intermittently but without any pattern although the longer the car is left the more chance it will unlock keylessly. One of the signals must be sometimes just strong enough. The same happens to keyless start, at the moment half the time the key has to be placed in the emergency position in the centre console and half the time it works from my pocket. Weird.


For the record, the boot/trunk antenna is located in the centre of the car, directly below and just behind the rear centre seat back.

Any ideas anyone?
