Which is this component, using in remote car key PCB?
They seem to be connected to the antenna connection (pins 23 and 24); looking at the datasheet, my best guess would be that 1 is a capacitor between V and ground, 2 is an inductor, and 3 is an antenna. Have a look for yourself to see if that is correct; it shouldn't be all that difficult to reverse-engineer looking at figure 7-3 on page 9 of the datasheet.
The values I can't tell, but they probably used the suggestions in the datasheet.
