I searched for an answer to this question, but could not find what I was looking for, though that is probably due to my lack of familiarity with the site.

I recently purchased an '05 TL (with navi and memory seating, I think I read somewhere that makes a difference). The prior owner did not have either keyless entry unit. Rather then go to the dealership and pay who knows how much, I searched ebay and found replacements are available for ~$20.

Most ebay listings provide a FCC number/code (like HERE), to verify compatibilty with your vehicle. Where would I find that information in my car? Any other tips I need to know? I'm not worried about programming it once I get the replacement, am just worried about getting the correct replacement.

Thanks for any help
