How do you program a keyless entry remote for a 2003 Chevy Impala?

Answer 1

This is out of an owners manual for a 2004 Impala (at least 2001-2005 should be the same) ... FOB PROG (Remote Keyless Entry Transmitter Programming) This feature allows you to match the remote keyless entry transmitter to your vehicle. To match the transmitter do the following: 1. Scroll, using the SEEK/PSCAN up or down arrows, until FOB PROG appears on the display. 2. Press the PREV or NEXT button to enter the submenu. BEGIN will be displayed. 3. Press the TUNE/DISP button to start programming. When the message PUSH FOB flashes, press and hold the LOCK and UNLOCK buttons on the first transmitter at the same time for 15 seconds. A chime will be heard to verify the transmitter is learned. 4. Repeat Step 3 for each additional transmitter. The transmitter is programmed now. You can either exit the programming mode by following the instructions later in this section or program the next feature available on your vehicle.
