Keyless-Go Question (Possible Repair)
I just bought an '03 S500 Base w/ AMG Styling Package (from factory). I only received a single key fob. I know you can get additional fob's and a keyless-go card from factory. However, I was wondering f for some reason there needed to be repair for that system (antenna's and such) ... is there a guide/parts list or is it a pain to have repaired if needed?

That system usually shouldn't fail. If your normal key fob is locking/unlocking properly from a long range, then your keyless go system should also be good. The antenna booster that sits above the rear windshield is responsible for both the standard fob and keyless systems.
If your car isn't locking/unlocking from long range then check the fuse for the antenna booster. Mine was missing for the longest time before I found out about it and was about to drop a lot of $ fixing the antenna booster.

It is locking/unlocking fine. Well at least it gets the signal as the alarm arms and disarms without issue. I need a PSE pump.as mine is completely gone. I don't have the Keyless-go card so I will have to talk to the dealer to get a replacement and programmed. Thanks for the info!
