Keyless entry remote receiver

[Supercross109]

Hello, I have a 2001 GMC Sierra 2500HD, the keyless remote receiver seems to be going out on the truck because i notice it is very selective on when it wants to work, from what distance, and every other factor in general. I even replaced the battery in the original remote and have reprogrammed an identical remote to my truck and it still acts the same. I opened up the dash to find the keyless entry receiver and have the part number #15732806 yet trying to order a new one I come to have found out that it is discontinued and cannot find one online to replace it with. My question is, can I get another keyless entry receiver from say a 2005 or 2007 or 2003 or any other suv/truck from GM and plug it in and just re-program the remote to the receiver, or is there something else I can do to get a new receiver even though the part is discontinued, or basically what are my options?
