Thank you and take your time. I'm in no rush, i can use the natural lock should it happen again and the rest is just(annoying) fluff in comparison

Update!!
I don't know if it's because i disconnected the battery the other day, or because i started a new SDD session, but the car CCF is now showing as valid and i can view it with no errors.
I'm going to go through and check it looks sane, as last in my eyes
Progress.

I think all is well. Diag is now doing things that just errored before. I think the battery reset did the trick.Steady on Kermit it could be playing with you
Hope not though and all is well
I'll go through things tonight when i have more time

Spoke too soon
Got in no problem but took ages to recognise the fob even though I'm used to exactly where to place it

It's now suggesting that the rf receiver isn't sending a signal.. is that the bugger in the roof?

the keyless module currently has not error codes
The RF receiver is behind the dash, the KVM has four (possibly five from memory) antennas, these are the ones that do the push-pull. Have you considered it may be the key? the history of not unlocking and then the KVM not doing the validation and problems with the NFC initialisation all hinge on the key being functional - which is a single point of failure rather than the KVM, it's antennae, the NFC antenna and the CJB....
BTW, it's always good practice to start a new SDD session unless you're continuing with a previous diagnosis. The only issues I see with your sessions are the the PCM not holding a valid CCF backup and both doors having issues with power to the locks & mirror heaters - did you at any point unplug the door harness'? it may be the issue is with the flex between the door and the body connector - that has nothing to do with the security issues though.

Thank you. The mirrors have never cleared about from the edges, probably need new ones. It's on the to-do list.
The door codes have always been there even after clearing codes. Never touched them and never had a problem with them either so i ignore it

Both keys don't work at the same time and it makes no difference whether I'm using one key or the other.
Difficulty with nfc could just be me in a hurry with the alarm going off at work

I was contemplating downloading the CCF then reuploading on case there's still something funky going on. SDD should verify it's all valid

I think it says communication lost/no signal
Here's the control diagram, as you can see, the KVM is 'key' to both functions, even if no DTC is set (for that relies upon the failing function being monitored and capable of setting a DTC) it could have an internal defect, the antennae, CAN & power are obviously OK as they are monitored.
As a DTC or dash message? even though both functions are within the KVM, it's two separate systems, for both to fail would indicate a general electrical or processing defect within the KVM.

Just looking on SDD it's currently saying communication to the rf receiver module has been lost.

As a dtc, on the dash it just says key not found when you try to start
