Progam a new remote to Hornet car alarm??

[SteveD]

Hello all

My son has a Hornet 725T car alarm and we recently purchased a used
Python 474P remote for it on Ebay. This is the same exact remote that
comes with the alarm when we purchased it new. Can anyone tell me what
the process is for progamming this remote to work with the alarm? I
thought I could find instructions easily on the internet....but haven't
had any luck.

THANKS in advance - Steve
