What do you mean hold the door lock on?That doesnt sound like the factory alarm to me?Do you have a aftermarket alarm installed?ALso when you installed the radio did you get the gm jumper harness for the radio install or did you just cut the harness to install the radio?

saturn1212 i have gm remote its a gm16245100-29 an i just cut them now you holled down lock on door an it starts still have no remote an no radio

Check the inside fuse box for blown fuses?Also you need to go over all your work.I have never seen a factory alarm cause that issue.

i went over all of the work an found that i have 3 fuses that don"t have power now open the fuse box no burned wirrers tested in side f box an no power still can thair be a fuse in dash some wair

Which fuses didnt have power?
