@ J.,
I don't know the part number, I just went to Tom in the parts dept and said "can I have one of these please?"

Part arrives tomorrow so the one in the pic is from my door handle and was only in the lock for 5mins for illustrative purposes
@ Scott,
Hehe you know those poor dealers have to make a living somehow.
@ G.,
You too? Both my driver's door & the boot mechanical locks have siezed. I've also tried copious amounts of lubrication with the likes of WD40 and silicone spray etc. I can now fully insert the key blade but lock still refuses to turn on the driver's door and the boot lock won't fully accept the key blade so there's no way it'll turn

The only lock that does work is the glove box

at least my RA can be safely hidden

Heh I always carry my spare key in my briefcase. I dread to think how much lock barrel replacement would cost.
@ S.,
Great idea! Hmm now I wonder if COMAND would take a 'live video feed' ?

BTW there's a shop called
Fineplan in Harrow, NW London that do some really tiny security cameras, my dad knows the guys there.
