Re: how to determine Hitag types?

This is only an Idea.
Disassemble the battery,and check if the backup-transponder is working
in the remote (passive LF for immobilizer).

Fourth-generation keyless entry/go IC (NCF2952/NCF2951)
} Increased sensitivity, 3 channel active LF interface for
125 kHz, 1 channel operation, plus passive LF for immobilizer
backup mode
