I have a 2003 mk2 galaxy, the remote central locking was working perfectly then stopped working for a while and we have accessed the car manually. I have now tried to reprogram the remote central locking fob. I have followed all instructions to do this but the led in the drivers door does not flash when I have completed the key fob buttons sequence. The fob goes into programming mode and flashes 5 times but the door led just stays lit for 10-15 seconds then goes out. I have replaced the batteries and even bought a new fob, same serial no etc siemens 5wk4 790/97/98 433,92 mhz but no luck. Does anyone have any ideas as this is driving me crazy now!!. Paul
