Pug 306 Central locking Works, Deadlocks Dont

Hi

Does anyone know how what to check to fault find my central locking.

I have a peugeot 306 TD hatch N reg. When I press the plip button,
the central locking engages.... however when i press the second
button the deadlock doesnt.

It was intermittent and has now stopped all together. I had the
problem before and it was caused by one of the rear doors not being
closed properly. The plip would lock it but pressing the second
button would not engage the deadlocks.

I seem to think its a problem with the boot lock, all doors seem to
close properly. I've had a look at the lock but cant see anything
obvious. The central motors obviously power up to engage the primary
locking. (The deadlocking doesn't attempt to run any locking motors,
it is making no futher action whatsoever).

Are there any sensors to check that the lock is fully closed? I cant
see anything.

The remote appears to be transmitting, though could it be an
electrical fault with the times (since you only get 5 seconds to
engage deadlocking)?

If anyoune has any ideas then I would love to hear from you.

Thanks a lot.

 

Why not try it by locking the doors manually with the key, in the lock, a
few times to make sure it works that way.
Another point; check to see if the battery in the key is okay; maybe you
need a new battery.

If you lock the driver's door with the key then hold the key in the
"locked position" for a couple of seconds the deadlock motor should
activate. Both motors are on the same fused spur, so it can't be that.
That would tell you whether it was the key or the lock motors
themselves, though I did experience a similar problem with a key where
the contacts on the button wore out and it occasionally worked.
