Jimny Ecu match keys

[poloman]

Hello, I have a Denso Ecu 33921-81a4, I read that it cannot be done immo off but only match keys.

The ecu has a 93c56 but the immobox a ASTI ICTC104.

Should I read the chip from the immobox or should I read the keys?

Thank you for your time, to read my post, any info welcome.
