My 96 type rs seems to have a setup in regards to the central locking I've not seen before on any fd I've had.
It has aftermarket remote central locking but the passenger door is not locking anymore, only unlocking from the fob. Drivers door is fine. If you lock or unlock from either the inside lever or the key on drivers door it doesnt do anything on passenger. My previous cars always switched the other side when doing this.
Took off both door cards and no sign of any aftermarket actuators anywhere. It seems both door locks have the actuators built into them.
Was there ever a stock keyless system on them and when was it introduced?, seems it might have been tinkered with quite a lot if not.
