Anyway , if anybody can help me with calibration it would be perfect.

I tried with toyota landcruiser 315 mhz key , and one bmw key. I does not see them at all.

Only 433 mhz peugeot key works and it writes FSK 433,8 .

That only if I enter calibration mode.

I normal mode, when it writes ” frequency ” it does not do anything .

friend,please do as following steps:

1.connect VVDI2 to PC, VVDI2 screen display ‘ VVDI2 ‘.Press and hold ‘ F ‘ button (frequency) until the screen display ‘FSK校准'(in FSK calibration mode )

2.FSK calibration with 315 MHZ frequency key,Press and hold ‘Lock’button of the key,buzzer will sound,then release,screen display ‘ASK校准’（in ASK calibration mode）

3.ASK calibration with 434.42 MHZ frequency key,Press and hold ‘Lock’button of the key,buzzer will sound,then release,screen display’校准成功’（calibration success）

Notes:FSK calibration recommend key number（with 315MHz）:8T0xx754C or 8T0xx754J

ASK calibration recommend key number （with 434.42MHz）:1K0959753N
