XZBMW  CAS4 1L15Y EEPROM question.
Hi guys, i have a question about CAS4 1L15Y EEPROMs.

I have two CAS4 modules, one with keyless and another is without keyless, both are with 1L15Y mask, i need to clone the one without keyless to the one with keyless, do these EEPROMs differ or are they the same? will keyless option work if i just read and write eeproms from one CAS to another?

TIA.

Same MASK (1L15Y) means same functions, no differences.

Maybe, the installed hardware on the PCB could be different.

yes, hardware is different, as Keyless one is with three connectors and non keyless is with two.

by Keyless i mean Comfort access.
