Centralized Kia Picanto Closing

Hello friends, greetings from Panama, I do not know if I entered the right forum, I just registered, this is my case:
I have a 2008 Kia Picanto that came with factory central locking, one day I was trying to dismant "Motorcito" of that door that was damaged, others that I must lower the door, but as I do if it even opens .... If someone has happened to him and can help me or have another opinion, I would appreciate them very much ..... greetings from the city of Panama.

If you do not open or fall with your key or with your hand then it is not a problem of centralized, it is another factor that is acting, you will go where a chapero to open the door because if you try to do it you can cause more damage, I do not think it affects what you realized at the door but rather a coincidence, luck.
