You read the different suggestions on that link i.e .?
Good news!
I tried some wd40 on the keyhole, as suggested, but it still would not turn any further. However, I then tried using the emergency key and unlock button (on the boot) at the same time, and on the 2nd attempt it actually opened.
When closed the lock once again jammed, so I opened it again as above to inspect the lock.
The mechanism was making all the noises to suggest it was working, but infact it was not unlocking.
After spraying some wd40 into the main lock mechanism and working it in with about 10 lock/unlock cyles, it came to life and started working as usual, responding correctly to the boot button and the keyfob!
Thanks to all who offered their advice!
