Central locking works off door key ok but not with fob.
Original fob had flat battery but after replacing still no led when tried so got replacement one from locksmith guy on E-Bay (spal) led works but when try to do teach ign on press lock off, on, off on 4th on should operate locks but having no joy at all, could a control box be faulty?

Thanks,
Peter.

 

might not be relevant but I was told when you take the battery out the fob press the buttons to release any charge still in the fob as putting a new battery in can sometimes scramble and reset the signal
