keyless ignition, engine start up vel satis

Hello, how can I turn on the KEYLESS IGNITION, on my 2004 VEL SATIS 2.2 dci-privilege. The KEYLESS ENTRY (open / close doors ) works well, but for STARTING THE ENGINE I must put the key-card into the socket, and I want it to be COMPLETLY KEYLESS. Thanks, Zoran
