XTOOL M821 Mercedes Benz All Key Lost Communication Adapter

The M821 Mercedes-Benz All Keys Lost Communication Adapter is used for programming Mercedes-Benz EIS modules in an all-keys-lost situation. Get the job done in half the time, in addition to reducing the amount of times you'll need to insert and remove the key emulator!

When the M821 Mercedes-Benz Adapter and the KC501 IR reader/writer are combined with your AutoProPAD G2 or AutoProPAD G2 Turbo, you can easily extract the EZS/ EIS key password which will allow you to program Infra-Red keys to DAS2/ DAS3 (FBS2/ FBS3).
