I have a 2011 c3 picasso 1.6 hdi , recently the central locking has started locking all the doors when I get out and shut the driver's door , this only happens with the driver's door. If I get in the car and shut the door the central locking activates , but if I get in and turn on the ignition ( but not starting the engine) and then shut the door it doesn't activate.

I've tried using the key itself to open and close the lock a few times , this fixed the problem temporarily but doesn't fix it after trying again , also tried resetting the BSI but this didn't fix the problem either.

Any help with this would be much appreciated

many thanks

 

Stu

Hi STU48. Have a look at the little button on the key fob that releases the key,to make sure that it is releasing fully.

I had a similar issue a couple of years ago. It only needed a small amount of "crud" to stop it releasing.

Hi all. ref to my previous post,The button on the key fob was connected in some way to the workings of the fob, the dirt in the little button was somehow stopping the fob working. Giving it a clean solved the problem.

Apologies Stu. Completely misread the tread.

It's quite common for the door lock motor solenoids to be a bit sticky (Both on the old Pics and the newer C3's it seems).   Maybe try cleaning it, or using some silicone/thin oil (WD40 attracts dust eventually, and makes it stickier).  You may need to take the door panel off, or try it from the lock panel on the door....  Have a search on here for it.  :)

Hi , I've already given the door lock mechanism a good spray with WD 40 , sounds like that maybe the wrong thing to do ! Will try and  remove it from the door and see if I can see what the actual problem is

cheers

Hi Stu48,

 

Did you resolve this problem? Mine has just started doing the exact same thing.

 

Cheers,

 

Tony.

No problem using WD40 to clean it but use a lubricant after it.

sorry for late replay , but it was some time before I got round to tackling this , I took the whole door latch mechanism out and ended up with what looked like this

_https://www.ebay.co.uk/itm/Citroen-C3-Picasso-Front-Driver-Side-Door-lock-Catch-/401416068593

cleaned it up as best as I could , put a couple of drops of 3 in 1 oil on moving parts and then put it all back together again and it worked ok . That was a couple of months ago and (touch wood) it is still working properly

Problem Resolved!

Hi All,

Tried the strip down and clean approach. Didn’t work I’m afraid. Saw a second had door lock on eBay (off a 2010 car) for £61.50, but decided to go for a new one for £124.60. Took me under an hour to fit (pretty easy as these jobs go) and now the problem is resolved. I asked the guy in Citroen parts dept if this was a common fault. He wasn’t sure, but when he checked the system he’d sold 8 this year alone!
