Dear all,
I am wondering if my 97 S500 remote has the computer chips in it? or i can get any used reomote fromt ebay and reprogram it? i saw some flip key remote has the back trunk open option, will that fit my car? (the original remote only has one botton and has the switch in the central console to open the trunk)

How can i determind if the keyless remote will fit my car?

many thanks!
