Door wont lock intermittently with fob and wont lock manually at all

[frayfray]

Hey all, 

I have a 05 AT 350gt coupe. I'm not sure if this is an actuator or not but my keyfob wont lock intermittently but then if i wait say like 30mins and try again it will work, I've changed the battery incase that was the issue but didnt help. Also when I manually use to key it will unlock 100% percent of the time, but the key will never manually lock the door. the key turns fine, but nothing happens. I am able to lock the door successfuly 100% of the time if I use the manual lock on the inside of the door. I would like to try understand why the key wont manually lock the door the most, As im happy to only manually lock/unlock until i can get the fob related issue looked into further.

Thanks I appreciate any help!

Have you considered taking the door trim off and having a look for yourself?

It does sound a lot like the locking mechanisms need a clean then grease, under the door trims

Sounds like you need a new door lock actuator. V35 common problem door lock and windows
