In summary:
Both of X431 Key Programmer and X-PROG3 can not use standalone, needs to use together with X431 series device.
But X431 Key Programmer is remote maker indeed, not immo programming tool. If you want to do immo programming to add new key, then add IMMO license for your X431 device with X-PROG3. Or use with IMMO Plus, IMMO Elite Launch professional key programmer.
X-PROG3 is good tool to work with X431 series to do immo programming. But x431 key programmer is tool for remote.
