M59 Berlingo central lock. Is it OEM or aftermarket?

Hi, I recently decided to try and fix the central locking on my Berlingo which stopped working about 3 years ago. It stopped working because a friend clicked the unlock and lock button many times quickly inside the car, and it suddenly stopped working. I thought that maybe it blew a fuse but it didn't. I know for a fact that on this Berlingo when it was new, the first owner did send it to an official Citroen dealership to get central locking fitted. I however and confused whether it was fitted with a OEM central lock system or an aftermarket one.

I took the door panel off from the driver side door, and found that the locking pin (the red thing that goes up or down when the car is locked or unlocked - not sure what its called ) is connected to something at the bottom right of the door - I've attached an image.

This electrical thing is connected by a green and blue wire, and goes above the fusebox under the steering wheel, and then goes somewhere under the facia. Same thing on the passenger door, again, goes under the glove box and under the facia.

I am also attaching a picture of the remote that I have, that used to work to lock and unlock the car.

To further confuse me, the Berlingo is missing the lock/unlock button under the 2 central A/C vents. - All images online of M59 berlingos have that switch.

My question is, is this an OEM or aftermarket central lock. Also, if aftermarket, where could the receiver box be mounted, since i'm hoping it has its one standalone fuse that has burned out. If its OEM, how do i diagnose it? since the fuse under the driver side it OK, and I definitely know that it stopped working in the way that I mentioned above.

Thank you for any suggestions on the matter

100% not original
A normal place to mount control units like this is behind the glovebox but really could be anywhere, depends who fitted it.

A citroen dealer fitted it. And I did see today that the cables are going somewhere under the glovebox. Maybe they mounted the aftermarket one at the same place like an OEM one would. I hope that the control unit has a standalone fuse, since it doesnt work at all. When using key to unlock door or the remote.

I found it hidden behing the fuses under the steering wheel. It had a burned fuse. Replaced it and all doors work well, just the side door works from time to time. Probably a bad cable or the motor its self. I didnt believe that a citroen dealer did it, but after dissasembling half the interior to find the box, the cable management of the cables was super clean. OEM like.
