R33 Central/door Locking Motor Mechanism Problem? Need Help A.s.a.p

[...::BROD'Z::...]

Hey ppl,

My passenger door wont lock at all so i had a look at it today. I took off the inside of the door and looked at the motor mechanism. It works good from 2 sides e.g. it works from the door handle lock to the motor mechanism - it works from the key hole on the outside to the motor mechanism..... but they dont work together and something seems to be stuck or broken within the motor mechanism????

I am wondering if anyone has a spare locking system to install inside the door... and if it is possible for me to do myself and save me some $$$.

Hope to hear some advice, cheers.
