Create Grey key data to program new EIS/EZS When all keys are lost
If the car has no keys at all or has the new BGA key
1-Read Old EIS with IR tool or OBD EIS tool, use MB IR software (MB IR without existing key)
This software will create a default password.
2-You can change the password as described in the pro manual, or use the default password.
3- Load the dump from Read folder and generate key using SKC.
4-Open MB NEC software.
5-Renew any used key.
6-Write the generated key from SKC (CALLED GREY KEY) if you generate more than one key, you can choose any key file that was generated using SKC.
7- Grey Key is written.
8-Insert grey key into the NEW EIS it should light up, P.S NEW EIS NOT REPLACEMENT EIS!
9-If grey key doesn’t light up, use the new ALL IN ONE Version to activate the EIS.
10-Renew the ESL and write the new dump using online or offline programming using MB tools.
11- Plug the EIS and ESL, and start the car.
P.S Any car that have a steering lock like 204,207, 212 need to renew the ESL
