Both generations belong to the Xhorse XK series (wire remotes) and serve the same purpose — generating universal remotes without a built-in transponder chip. The 2nd generation is an upgraded version with several improvements:
Programming method
- 1st gen: Requires a cable connection. The remote must be opened, the battery removed, and the programming cable plugged into the white socket on the PCB.
- 2nd gen: Dual-mode programming — supports both wired and wireless generation. You can program it without opening the shell or removing the battery.
PCB color (quick visual identifier)
- 1st gen: Green PCB.
- 2nd gen: Red PCB.
Transceiver chip
- 1st gen: Older chip.
- 2nd gen: Upgraded XM5118 transceiver for faster response and improved compatibility with VVDI devices.
Power consumption
- 2nd gen has approximately 75% lower static current and 30% lower operating current than the 1st gen — meaning longer battery life.
Anti-static protection
- 2nd gen includes enhanced anti-static protection on the PCB.
What stays the same
- Both generations have no transponder chip inside — if the vehicle requires an immobilizer chip to start, you'll still need to add a separate chip (such as a 46 chip or Xhorse Super Chip XT27A01).
- Both work with VVDI Key Tool, Mini Key Tool, Key Tool Max, Key Tool Plus, and VVDI2.
- Both use a CR2032 battery (not included).
- Key blade is not included with either.
