Sorry, having spent so much time on this and other car groups I have
forgotten that quite a few people have boots and bonnets...Anyway, Kiwis
might be on the other side of the world but are 'almost' British...
OK, locking the boot, two choices (when using the boot lock). In both cases
start with car unlocked.
Turn key clockwise all the way and withdraw key. You will have heard the
locking system operate and the door pins will have dropped.
Open central locking on a DOOR lock.
Now press knob on boot. Boot should stay locked.
Boot can be opened by inserting key and turning anticlockwise all the way
Do it gently and test in which positons you can withdraw key.
With boot open from above lock car with central locking from DOOR. Try the
boot; should be locked.
If you lock car from boot then, having turned key all the way clockwise,
turn back 90 degrees to vertical position and withdraw key. This will not
activate the deadlock.
If the above doesn't work (or something close to it) you may have a fault.
In that case try a dealer for checking key locking positions on the boot
I hope this helps.
