I've had both of my rears go, though a couple of years apart. Replaced both with used items from eBay and they've been fine since.
With the rears you don't need to take the door card off. You just need to remove the trim panel from the door card. This provides enough room to remove the lock.
Thanks for info, by the sounds of it it's a common
problem, it's my rear right what doesn't work, I traveled 300 miles for my
k1 but didn't think to check rear doors, I soon realised when tried to put car seat in and wouldn't unlock with key, it's a bit annoying as having instant access to all doors by remote is essential but hopefully be fixed this weekend
