Remote Central Locking Solenoid vs Key Locking

[Jsa274]

Morning all,

Apparently my Galant started making ‘alarm like noises’ according to the Mrs.. so I went and checked it out. Sure enough, the front passenger door could be opened despite the car being ‘locked’, and without triggering the alarm too.

When I use the key to manually lock the front passenger door (after the remote central locking secures the rest of the car) it renders it unopenable as it should be.

I am assuming the remote operated lock solenoid is linked to the mechanism that the key operates?

Next question, are remote lock solenoids easy to obtain if that is the cause of the fault?
