So I created a 3D component based on the undamaged one on the driver's side to print on a 3D printer. The material I used is PET-G. It is stable, the lock has been working for a year without any problems.
My model is a copy of the driver's lock, but in Slicer you can just mirror the model and you have a model on the passenger side. If you're interested, send me a private message
