remote for a 96 vw golf gl

i am tring to hunt down a remote. i went to a vw dealer and they told me that the 96-97 were sent out and had aftermarket alarms on them.
i was wondering if anyone could help me out with the manufacture of the alarm. or could i get a keypad from ebay (one that states can be
programed to any alram :screwy: ). if i take the second option how do i program the pad.

It was made by a company called Code Alarm.
