If you have central locking on it it could be that the motor is either kaput or the lock has stiffened up and needs attention to make easier to work if anything like the espace they are fairly easy to work on and you can get seconds from a scrap yard sindicate that is or used to be on the forum somewhere.
all the best
I have a keycard and the Laguna has central locking. If the lock has stiffened, how does one attend to the lock itself/ or what do I need to do? Or is there something else wrong which I need to be aware of?
Has anyone else had this problem on a Laguna?
Any advise is appreciated.
