Alarm fob issues

Hi, two questions. Ive had a look through the threads but can’t find my answers. I’ve just got a 2002 Bugeye Impreza GX wagon. It came with the key fob with 2 buttons and a sigma AC110 fob. Neither lock/unlock or arm/disarm. Fresh batteries in both. I’ve read up a bit and thought I could reprogram with the keypad but I don’t seem to have a keypad!! I’ve looked in the coin holder and behind it where the fuses are, in the glove box and arm rest box. Am I missing something? Do the keypads get removed? TIA
