I just bought a 2005 Mercedes C230 and I have two Mercedes electronic keys - one works as a remote - one works to start the car - how can these be combined/programmed so they are both fully functional?

By remote, you mean to unlock the doors, not remotely start the car? –  Gabriel Mongeon Aug 6 '13 at 19:14
Can you post a pic? Sometimes the luxury brands provide a valet key, so your locked compartments remain locked. –  FossilizedCarlos Aug 6 '13 at 23:42
