04 remote problem

my remote completely died, i changed the battery it worked for two weeks then it would work one minute but not the next now its completely dead, even after i changed the battery and tested it at autozone on their remote sensor thing,
anyways i got a remote from a 99 oldsmobile alero and i tried to program it to my truck but it wont register.

do you think the olds remote will work maybe im doing something wrong? any help is appreciated.


heres the directions i used:

Transmitter Programming Procedure (Method 1 - No Tools Required)
Close all the vehicle doors.
Insert the ignition key (http://www.automotiveforums.com///l) into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
Repeat the previous step to program up to four transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation.
