I cannot lock my car with the key from the outside. (not central locking)?

I have a W reg VW polo (Mark III facelift 00-02) and i recently installed some new speakers,finished that job but then i noticed that the front drivers door lock doesnt work properly.





Basically i cant lock the drivers door with the key from the outside, however i can unlock it with the key from the outside. The door still locks from the inside so the barrel cant be broken.





Is the lock broke or have I just knocked something off when messing around with the speakers??|||The linkage from the key to the locking mechanism probably needs to be adjusted. It is reached by removing the panel from the inside of the door.|||Well there's no way you can fix the lock without getting to it.


If this was my car, i'd take the door panels off the inside of each door.


Look at both of them, the door that locks properly is what your other door should look like.


What you see that's different is what is wrong with it.
