Fabia 2008 AKL, I used Xhorse VVDI Key Tool Plus to make a key by lock, read the pin from the engine control unit. But when learning the key, the unit does not accept immobilizer, just keeps lighting up (not flashing).I tried ID48 and ID48 tp 24, doesn’t work

Expert experience sharing:
Before you program a new key, put the ignition on for 30 min, after this just learn the key., without making ignition off. It will work. Please use ID48 tp 24, you can also try with Id48, maybe it works.

Finally! solved!
35 minutes ignition on, then no ignition off and on (diagnostics says off/on ignition over learning) and immobilizer is learned. I used ID48 blank.
