My central locking remote failed after disconecting the car battery!
The bonus was, the mileometer began to work again after re-connection. LOL!
I saw this link while searching the forums.
You will be pleased to know it worked for Me!
Saved Me mega bucks too!
I also got My Espace £300 cheaper for not having mileometer working.
Hope this works for You!
