Door lock mechanism - which make ?

[ronspeedsix]

I have a problem with my door lock (driver side). Normally when you close the door it catches the door in two clicks. At the first click the door is not fully closed but the mechanism catches the door preventing it to open.

On mine this first click doesn't hold the door. The second click however works.
I've had the mechanism out but it is a clinched unit. Think I need another one.
Does anybody know which make it is ? Or anyone a spare ?

Looks cavalier /vauxhall to me when I last looked at mine

But could be wrong.
