Boot does not always lock......

[sprout99]

what should i be looking for?
very hit and miss

Mine never used to, then it decided it would for about 6 months, now it does not again.

I dont know about the internal mechanism, but not being able to get your key into the boot lock and turn it is a common problem due to the design of the rear of the car - all the rain and gunk cloggs it up nicely.

Can you hear it trying to move when you turn the key?

[Reasty]

Do you mean it dosnt lock on the central locking or it doesn't lock when you use the key?

[sprout99]

can't get key in......

the lock mechanism works when locking central locking but does not always lock boot

the drivers door was a bit hit and miss.......took grommet out of door and lubed rod all ok now
so i reckon rear will be similar

You will probably find the mechanism and or the lock is full of crap,i had this problem a while ago,i removed the lock and took it all apart,cleaned it up and then refitted it and all is fine now,just remember how it comes apart as there is lots of small bits inside the lock including a tiny ball bearing that is more than easy to loose,also check all the hoses from the central locking pump are all fitted propery
(this is in the boot) and that the solenoid that operates the boot lock is working correctly.

boot lock was crudded....woudln't shut first attempt.

i'll have a look later on. i guess it'll be muck and oil and general need of some TLC

[sprout99]

the bar that is activated by the central locking was rusted

all free and definitive now

Exactly the same happened to mine - had to get a lock mechanism from the scrappy
