2006 Mercedes-benz c230 Remote Keyless Entry Programming? - mercedes keyless programming

Hey guys,

I bought a 2006 Mercedes-Benz C230, the remote works very well, lock / unlock, but no sound when you push your luck / unlock button.

No idea how to fix the problem? or someone familiar with the instructions to configure the vehicle by remote control?

I appreciate any help.
