Central locking!

[96TW]

Hi guys,

I don't really do this whole 'online forum' stuff so please forgive me if I do something wrong.

Anyway, I've just bought an '03 plate Multispace Forte 1.9D with only 44.2k miles on as my first car! One problem, the central locking doesn't work. When I press the lock button on the key or on the centre console it sets the alarm and you can hear the car trying to lock the doors but they don't lock. Can anyone shed some light on this issue.

Thanks in advance,

Tom
