Felicia factory Logic 600 alarm/Imm system

Help;

Just purchased(4 days ago ago my first Skoda)

My (1996)Felicia Bohemia estate is fitted with the central locking /alarm/immobiliser factory "system Logic 600".

My problem is getting a replacement FOB transmitter, Skoda dealers saying its too old, Skoda UK, just not answering, please does anybody know where I could go for a replacement FOB, getting a spare ignition/door key appears not to be a problem, just the transmitter FOB is the issue.

Would appreciate your experience, or pointing in the right direction, as I feel this must be a standard cry for people buying second hand cars.

Thanks a lot
