Your key are programmed & registered in UCH ( start the van ) but is not programmed to RF function , pre-code is OK but RCF part of pcf7946 is virgin like new key !

What pcb use? China or original 2 hand? China key problem! We change pcf7946 to one orig. Pcb make precoding and remote work fine and car start. With China pcb only car start--remote not work

Anyone can confirm that cn keys not work? I doubt that all not work as saw clients with aftermarket keys

Chinese key work very good, i have no any problem. Here is config that i use Kangoo, Clio, Traffic, Master

It use PCF7946 not 7947. One or 2 buttons
