Central Locking Anomalie

[Agent mMm]

Hi, I have a strange anomalie with my central locking that I'm looking for some advice/help on. Essentially, if you lock the car with a key from the drvier's door or the radiokey the locks jsut cycle. If you lock/unlock the car with a key from the passenger door, everything works well. If you lock the front passenger door manually and then try the dirver door or radiokey, the other locks all lock but when you unlock the passneger front doesn't want to know.

My first thought was the passenger front lock needs replacing, but if it works fine when you use that then surely not - so what next??

Any advice, insight etc greatfully received.

Cheers,

Dave
