When using the key my central locking is working fine. But, when using the remote fob it does not. I've tried to reprogram the key but after the chime sound (which indicates that the programming mode is ON) nothing happens when I press/hold one of the fob switches. I have also tried replacing the battery and the micro switches in the fob but still the same. Then I've tried to program another fob (borrowed from my uncle, same car, same fob type) but still the same.
Any idea how to solve this issue? Central locking module is 98AG 15k600 DB, CL, RF. How to ceck if the module is OK?
My car is focus 1.8tddi 1999.
