Re: BOOT wont unlock ???
I suspect that the lock in the boot has broken or atleast the plastic "lever" attached to the electric release mechanism . If you access the boot from the rear seat, you should be able open the boot with the emergency lever which is on the side of the boot lock iteself. NB Bootlock is on hatch.
Same happened to me. If you attempt replace the lock yourself, be warned that the rear hatch interior cover is very brittle. Dealer broke 3 on mine ,including the original, whilst relacing the boot lock under warrantee.
