factory keyless not working

[primal1]

any ideas? the relays under the dash dont respond. went into oreilly"s and tested my remote. came out fine.

did you just test the battery or the actual remote? gm remotes are junk and the contacts in the remotes go bad and they wont work

what year?

you bridged the 4 and 8 pins on the obd2 plug

What year is your truck? If your OBD1 you have to ground pin G of the ALDL connector to enter program mode if it lost its program

im assuming your locks still work off the door switch right? also ive taken many old remotes apart and look for old cracked solders that can loose contact
