This morning my boot lock failed. Chucked something in the boot, went to the shops, then the boot wouldn't open when I got there. At first, I could hear the whirring of the servo (or whatever) when I pulled the internal release switch, and also if I pressed the external boot button with all four doors unlocked, but the boot stayed firmly shut. However now that whirring noise has ceased to be when it comes to the boot, though all four door locks are working normally.
The whirring sound stopped happening after I'd hammered the mechanical part of the key into my boot keyhole. I found out last year that the never-before-used key lock on the boot was partially seized after I tried it for fun and found the key didn't go all the way in. Even a dousing of WD40 didn't help so I gave up. Now the key goes in (I only used a light tack hammer and worked the key in and out before it went all the way down) but the surprise-surprise, the lock barrel won't turn.
Since I've a limited understanding of how the boot release works, I'm not sure what component initially failed to prevent the boot opening, or why the servo noise has now stopped, or whether I'll be able to open the boot with the button if I can get the lock to turn. I wondered if I'd blown a fuse somewhere but manuals and handbooks seem little help in isolating the fuse, other that to tell me fuses are located in two areas under the bonnet and...in the boot! The problem occured only an hour before I had to go to work and I've got home in the dark, so no time to further investigate.
Does anyone know if the boot lock barrel turns anti-clockwise, or clockwise, to unlock? After another WD40 dousing and an overnight stand I'm tempted to try pliers on the key in the morning.
Thanks in anticipation.
