remote for keyless entry

anybody know if someone makes an aftermarket remote for the keyless entry on these cars??? mine came from the factory with keyless entry but when i bought it it was gone. GM wants $100 for one which isn't that much of a raping, but if i could find one cheaper i would buy it. thanks in advance

get the part number and FCC number from GM, and go buy one on ebay for 15 bucks.

sweet!! thanks man i realy appreciate it. i love this car, i have had a lot of other cars and this one rides, handles, drives great. and is amazingly comfortable, wish i had known how nice these things were before.
