I have an LDV eDeliver 9 2023, and have successfully obtained the security code from the car, and removed all keys.
I can't add back the OEM key fob (or any others), which have left me with a rather expensive brick in the driveway.
I have a KM100E
What I've done:
Immo, Autovin, System Selection
Keyless System, Keyless System(CAN)
Remote Control Learning, Add keys
Start, <enter security code>
Step 1: Security Access Success
Step 2: Check Status Success
Step 3: Key Relearned Failed
A dialog pops up:
Add keys
Front Oxygen Sensor Heater
Shorted To Ground Or Open
(note: this is an electric vehicle, so it shouldn't have an oxygen sensor)
