Basically months ago I had a battery problem and had to replace the battery. At th he time I had no problems with the central locking of the key or windows but after the battery was changed to an OEM standard replacement these things dont work at all. The only things working is the speaker and mirror control.. it's been plugged in loads of times with no codes and looked st th he wiring and seems theres no breaks i can find.. Anyone got any ideas it's doing my tree in ?
