Hi Chuck, I'm new here having just bought a 97 TLC a week ago and am still reading all the posts and FAQs, but I thought I could try to help you.
My 97 TLC came with one Securikey+ remote (key and plastic all together). It has the same "FCC IDELVAT 6B" that you have on the back. I found a crowd off of eBay (
www.keylessride.com) that sell just the black plastic part with the buttons and I ordered one (I also ordered some blank keys off eBay - still waiting on those). The remote arrived today and I followed the instructions to program it. It worked for me.
Try these - I hope they work for you:
1. Turn ignition key to ON.
2. Push the red light switch 6 times - in-out-in-out-in-out.
3. The red light switch should flash once and the horn should beep once. If it does not, turn key off and start at step 1 again.
4. Push the lock button on the remote. The horn should beep once. If not, check if your remote battery is flat - you said you had it for a while already.
5. Push the red light switch 2 times - in-out. The red light switch should flash twice and the horn should beep twice.
6. Push the unlock button on the remote. The horn should beep once.
7. Push the red light switch 2 times - in-out. The red light switch should flash three times and the horn should beep three times.
10. This step is supposedly to program "channel 3" whatever that is. You could try to push the green button on the remote? I did nothing here - I just waited for about 30 seconds and the horn beeped by itself - I figure it timed out?
11. Turn ignition key off and exit vehicle.
12. Close door and try the remote!
Hope this helps! Keith.
