Key Fob Programming???

[oldnick]

finally got round to changing the batteries in the key fob for the chief's remote
and so now have 2 remotes which lock/unlock with appropriate flashes for my 2000FL sport [ using the key in ignition system ]

HOWEVER whereas both seat memories are recorded and work by pushing the buttons on the drivers door only the number 1 key automatically sets up the seat etc when used to open the drivers door

so clearly I am missing something ! must be simple but what is it ???
