Problem:
A customer tried to use the Xhorse VVDI Key Tool Max Pro to program an Xhorse XSKF01EN Remote for a 2022 MG HS. However, when entering IMMO programming, the device could not communicate with the vehicle.
The following error appeared before key programming started:
“Request seed failed! – Invalid format – Message length error ERR: 7F2713”
Solution:
Please try to use “Smart key system” function and follow the on-screen function introduction to operate.
