Hi kui,
"Emergency Kinetis Device Recovery by Full Chip Erase" in S32DS debug configuration window may helps.
If still not work, then please try to use the P&E recovery utility mentioned in Bricking and Recovering FRDM-KL25Z Boards: Reset, SWD Clock and Low Power . This tool is able to keep the board halted modem then you can use S32DS program or debug it.
It is also recommended to read a good application note: AN12130, Production Flash Programming Best Practices for S32K1xx MCUs
Best Regards,
Robin

Hello Robin,
Today I found a problem ablout S32K146 device security.
if the WRITE_PROTECTION flag has been set, then Key can't be erased, CSEc keys saved in EEPROM backup area, then Erase all Blocks command can't be executed.
so how to remove security to unsecurity except backdoor key method?
and at the same time, debugger can't remove the security to unsecurity?
wish your help!
