2003 Silverado Keyless Entry???

I recently purchased a 2003 Silverado and it did not come with any remotes. I have one from a 2000 Z28 that I used to have. Will this remote work? The # on the back of the remote is GM 16245100-29. If not which one do I need and how can I program it. I looked through the forum but there are so many different models. Please email me at [email protected] with any help. Thanks, Steven

It's the wrong remote, but when you find the right one please do the following

Close all the vehicle doors.
Insert the ignition key 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 4 transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
Operate the transmitter functions in order to verify correct system operation.
