I have a 2009 C300 I’m selling with a single worn key fob. I ordered a newer fob on eBay but the internals are different. Mine has a round red panic button, the new one has a red triangle.
I can’t swap the chip like I thought I could, so I’m wondering if I can code the triangle key to my car since the hard key fits in it perfectly. Does anyone know what the difference is between the two styles?
