We just purchased our 2005 CR-V. It came with only one key. The remote keyless entry transponder type. So we ordered two blanks from ebay (could have been the mistake). When we took it to have it cut and programed we were told that it is stamped with an "R" and we need one stamped with and "F". The ebayer doesn't know of the two kinds of keys. Does anyone know about the two different kinds of keys and where we can find "F" keys?
