Replacement Keyless Entry and Keys for 1997 C280
 

Anyone know the process for getting a replacement keyless entry fob and keys for a C280 1997 Mercedes. I am just buying this car from my grandmother and the fob was lost. I have one set of keys. Ideally, I'd like two sets of keys and two fobs.

From a brief search it looks like the dealer is the one way to do it (perhaps the only way) and that it can be very expensive.

Thanks!
