97 Deville new keys

[farmngmom]

Just bought a 97 Deville. Problem is that I got it through a state auction. When I picked it up at the it only had one set of keys (and they weren't the gold ones you get when you buy it new) and only one "keyless entry" controller (which doesn't work even after I put new batteries in). I love the car but do get worried that somewhere out there is another set of keys. Do I have to go to a Dealer to get it programmed for new keys? Is there a way to re-program the keyless entry controller.

Note: Before starting this procedure, both transmitters must be present. For programming purposes, procedure questions will be answered with a YES or NO response. FAN UP is YES. FAN DOWN is NO.

Analog Instrument Cluster

1. With the ignition in the "RUN" position (engine does not necessarily need to be running, but it will work either way).
2. Press OFF and WARMER (or the OFF and PASSENGER WARMER buttons) on climate control panel simultaneously. Instrument Panel Cluster (IPC) will light all telltales, then go blank. System is now in DIAGNOSTIC MODE. After diagnostic mode cycles through and stops, press FAN DOWN button until "RFA?" is displayed, then press FAN UP. If "RFA DATA?" is displayed, press FAN DOWN. If "RFA OVERRIDE?" is displayed press FAN UP button.
3. If "RFA S00 NO OVERRIDE" is displayed, press FAN DOWN. If "RFA S01 PROGRAM FOB #1" is displayed, press FAN UP button.
4. IPC will show "0" on right side of Drivers Information Center (DIC) display. Press WARMER button on the climate control unit until "99" is displayed.
5. Press and hold TRUNK button on the transmitter. While holding TRUNK button, press LOCK button and hold both buttons for a total of 3 seconds. Locks will cycle when programming is complete. If transmitter is not programmed within 30 seconds after entering "99" on the display, system will default and you must begin at step #2 again.
6. To program second transmitter, press FAN DOWN button until "RF S02 PROGRAM FOB #2" is displayed, then press FAN UP. Repeat step #4.
