Actually after erase then EZS is not activated of course all keys is disabled.
Just insert working key or program new key to activate then the EZS will back to normal.
Get better understanding rather than just struggle with eep.

This is a complete dump of your lock for recovery, Flash, eeprom, shadow/ If necessary, I can generate keys. Good luck

What is the reason for the failure of some EZSs ? ( key is ok ) When you insert the key in to EZS and press the remote button, the remote light turns on and this this is an abnormal situation , It means it does not accept the key
What is the repair solution? mcu data is ok (read & write mcu data is ok) , pcb soldering is ok , The coil is ok
Is the MCU broken? or ?
any one can help me ? i have a EZS w211 (2115452308) with mcu 9s12 ST and mask 4L40K
Thanks

Good afternoon. See EZS parameters in DAS with the key inserted.

Many issues cause the EZS to not read keys properly. Simple physical ones like a failed switch, or IR transceiver, or the coil not powering, failed release coil, failed CAN or LIN transceiver. Sometimes flash in the MCU is corrupted by poor jump starting procedures or key programming attempts and sometimes the MCU is indeed dead. I approach repairing these by carrying a number of donor modules, do a clone or a virgin and personalise after retrieving enough data from key, ezs, ecu etc. Then the dead module sits on my workbench waiting for some spare hours to test everything, repair it and then the module goes back into stock or in the bin for donor parts if not recoverable.

But yes your first step is always checking the live data and seeing that the EZS does indeed communicate and what physical switches it sees and if it sees them in the correct state at the correct time.
