UPDATE: ALL EZS chips are supported now: HC05, HC08, HC12, 9S12, NEC (auto detection)!
Using this service/page you can calculate (generate) up to 8 keys by yourself from EIS/EZS dump only (without removing any part).
MB Key programming (HOW-TO):
1. Read out EIS / EZS data and save the result (dump).
2. Upload the dump to this service/page.
3. Calculate the keys.
4. Download the key dumps.
5. Flash/Write the key MCU with a key dump (using a NEC programmer).
6. Start the car using the new key! Sometimes you have to place the key about five times in EIS/EZS, each time around 5 seconds (just the first time).
How to read EIS /EZS data: Read with tools such as: ETL universal, CAS3/9S12X Programmer, IR-programmer, Xprog-M, Rosfar R260, NEC reader, MB key prog etc..
How to write Motorola MCU (.021 key): Flash with tools such as: Xprog-M, ETL universal, orange5, UPA etc..
How to write NEC MCU (.051 key): Flash with tools such as: NEC key programmer etc..
Watch out for clone devices (they are not recommended) for writing a NEC key! If the (re)writing doesn't work, try to write the dump on a blank / virgin NEC chip.
