Programming remote!

I need to know how to program the keyless entry remote on my 95 astro ,my impala was easy! thanks in advance!!!!!!!!

My 95 responded to the following....With the key off, jumper A-G on the ALDL. The car will energize the PL's to let you know it's in programming mode. Push a button on the first fob, and the car will again energize the PL's to let you know it's accepted. Push a button on the 2nd fob, and it'll do the same thing. Then remove the jumper and you're done. Make sure you program both remotes at the same time.
