Pros and Cons for Mercedes Key Programmer


Pros: VVDI BGA MB Never had any fails read with prog and calculate with mb prog.

not only supports Mercedes bga key online calculation, but works well on new Benz models supporting IR/OBD


VVDI MB need to work with VVDI PROG sometimes, some EIS and ecu that you can not do with vvdi mb tool independently. Such as w201 EIS or sprinter 906, and VVDI is little pricy for individual owner and DIYers.

For old Mercedes, VVDI need to dissemble EIS to add a new key.




CGDI Prog is the fastest key programming tool to calculate mercedes password and add key at present.

CGDI MB  can read FBS4 key information and check if the keys work correctly, while other mercedes key programmer can’t. Supports Mercedes FBS4 W447 cluster mileage reset(not all W447 cluster versions)

On old Mercedes, cgdi mb is able to OBD program a new key, no need to disassemble EIS.

Mercedes key programmer---CGDI PROG

Mercedes key programmer---CGDI PROG


CGDI prog not work with new Mercedes very well, doesn’t support BGA keys. CGDI work not on all by OBD,W906 Sprinter don’t work(CGDI supports W906 only CAN BUS not K-line), W230 SL55 AMG 2006 don’t work.


Original NEC Pro57

Pros: can program keys directly without dissemble,is the most powerful and best NEC programmer for Mercedes Benz, software supports update online.

Cons: this tool is very expensive, need 7000$! not suitable for DIYs or individual owners



Pros: AK500+ is the best mercedes key programmer for a beginner or anyone who looking for a decent mb key tool.AK500 is a good eeprom programmer. No write MB key. It can renew NEC IC, works fine geniune key(renew nec chip).

Cons:Can work for only ori NEC keys and older clone. Relative stable tool, but supports only old models and can make only ori NEC keys and older clone.

AK 500 kills the remote bytes and the remote door locks does not work anymore. Kills the flash of 9S12/HC12 EIS as well.

Mercedes Key programmer Conlusion

VVDI BGA tool and CGDI Prog are very popular at the market, are suitable for both DIYer, individual and mechanic . Many customers ask for FBS4 key tools, but there is no tool can caculate FBS4 key in the market yet. For FBS4 key programming,only the genuine xentry and daimler FBS server work.
