Central locking and keys

Post by cliffk » Fri Jul 06, 2018 5:34 pm

Hi I have 2 things I need help with if I'm on the right forum
Car is 2003 406 estate
1 central locking packed up from the key fob a long time ago but I could lock everything from the drivers door with the key. Today using the key only locks the drivers door so I am having to lock all the other doors and tailgate manually using inside locks and key in tailgate.
Any ideas how to fix.

2 key fob.
I want to replace the key fob, just the case, I have seen empty cases for sale which use your own key blade if it's the 'push in type'
My key blade is the push in type as there is no retaining screw I have opened my fob case no problem but cannot see how to release the blade from the case, any help appreciated

The blade needs a good pull with some molegrips though you have to be carefull you don't damage the blade.
I'm not too sure on your other locking problems they may right themselves once you can start blipping your way in.
I had to sort my drivers door out earlier my lock just spun but I noticed after fixing it my c/locking had a paddy and I had to resync a few times.

Thanks for the reply central locking from the drivers door key seems to have sorted itself out now, for a while anyway. Will try the blade removal method mentioned assume it's just a matter of pushing it into the replacement fob.

Yes their are guides around somewhere think theres one on this forum, I need to replace my fob at some point my buttons are just about hanging on.

Just looked on youtube there is a video on there, providing the new case is a push in aswell just pull blade out push in to new case then swap inners over.

Don't forget to swap the transponder chip over too..
It's hidden in the top corner of the fob - without it the car won't start...

I fitted a new fob and one of the tiny tact switches in my wife's 206 estate as it was damaged, works a treat now but when I first fitted it wouldn't lock although if you locked it with the key it would unlock with the fob, problem was sticky lock mechanism on the drivers door, gave it several doses of penetrating fluid, works a treat now
