Central Lock location

Hi!

I have a Mazda 626 1994 1.8LX. At the moment I am having some problems with my remotely controlled central lock which keeps locking up the car by itself. So, I was wondering if anyone know where the central lock "controller"/IR/Radio-receiver is located?

Thanks!

The door lock timer unit should be located behind the lower, outer side kick panel on right hand side, just to the outside of the footwell and forward of right front door. Keyless transmitter unit is under the rear package tray, just behind the rear seats.
