The 2002 S I just bought has no buttons on the key. Was it an extra cost item to get a key fob with the capability to open or lock the doors?
Other than my friendly BMW dealer is there any other option for a spare key (I only got one from the seller)?

 

I also just bought a 2002 S and my key has no buttons but they only had one key.

 

I'm not positive on the early ones if keyless are on all mini's or not ... I'd ask the local dealer
unfortunately the keyless fobs are pricey from the dealer and will need programming ...
($140)
A good locksmith can cut you a key for $20 or so

 

The local Mini dealer (Ft Lauderdale) charged me $ 190 for the key and wants 1/2 hour labor (est $ 70) to program the buttons.
I did try a local garage (MTM Bavaria) and their computer was not able to do the programing.
