hi guys newbie here ive got a 1.9tdi 2002 ford galaxy i recently replaced the car battery as it was old and needed changing, ever since the battery change the centrol locking is out of sync, i cant open my doors with the remote fob and when using the key only the drivers door opens, i have to manually open all the other doors by hand. the remote key fob and the black ford key were all working fine until the car battery change. any help would be appreciated thankss guys
