What is the current on a Mercedes EIS?
When a key is inserted and the coil is switched on the current goes to ~130mA. There is a microswitch that is pressed by the barrel when the key is inserted. If the current doesnt change after key insertion it is either the switch or MCU1 problem. If the key is not recognized (not from this car) the current will drop to 30mA.
What kind of EIS does a Mercedes W220 have?
Early W220 EIS is similar to the W210 EIS with 2 HC (7)05 inside. Usually found in 1999-2001 models. Strange, but the key data can be in either one of the MCUs. So you just have to pick one and remove it.
Can a Mercedes EIS read an AK500?
ETL reads them around 80-90%, some can never be read. AK500 is doing 99% of them. If it doesnt read after first few attempts heat the MCU a bit, if it doesnt read again heat it up a bit more and so on. Do not overheat it, you will kill it if it is not already dead. Keys can be made from the 2nd MCU that is inside.

What should I do if my Mercedes EIS is not working?
Always first step is to read diagnostic trouble codes with DAS. If you work on a petrol car, always take a look to the ecu coding string and write it to a piece of paper. On diesel cars no problem. Before remove EIS, always remove the ESL.
