Automatic door locking stopped happening

duddly · 02-07-2009, 05:30 AM

I just noticed that my doors no longer lock themselves when I get to 10/15mph.

I can lock them manually from the button on the dash or the key fob.

Does anyone know anything quick to check? This is a 2008 cabrio.
I once had a problem where the doors would not lock via the key fob and that was related to the tailgate not being fully latched (but that is not the case this time).

I can/will take it in for warranty service, but was hoping that someone had seen it before and maybe I am missing something simple.

thanks.

Have you tried re-activating the feature? My manual is in the car so I can't look up the exact procedure, but it's very, very simple. When All Ball came back from service last time, the auto-lock was inactive. I simply activated it again, and all is fine now.

Thanks. I just woke up, so that was the best I could offer while my brain we still in sleep mode.

Thanks! That did the trick. I used the steps you pointed out to re-enable the auto-lock feature and it is working fine now.

Wow that was fast! Thanks again for the replies.

Thanks for this posting. My auto locks stopped working also, so I'll try this fix tonight when I get home.

I noticed it after this post had started and realized that when I went around to open the wife's door to let her out. She had pushed the unlock same time I did so it shut it off. So, now I don't push my unlock on the keys and make sure she just unlocks the door. Hehe.

Hi I have a problem switching on my Roadster. The thing is that the key didn't function and the car was locked. So I had to remove the cover from the "manual" opening and then as I tried to switch on the car I got the "key" message on the screen and the key does not function any more.
Does anyone have a clue on what I am talking about and is then able to help?
