2003 Sl 55 amg
Keyless GO
Just bought a 2003 R230 SL 55 AMG and it came with keyless GO card as shown. I changed batteries but it still does not function for doors or starting. Do I need to Pair it?
Any advice would be appreciated

Dont know if either of these documents will help

I have no experience of this earlier keyless system (and very little of the later system fitted to my car either....)
