M821 Mercedes-Benz AKL Communication Adapter

The M821 Mercedes-Benz All Keys Lost Communication Adapter is used for finishing and optimizing AKL programming for multiple Mercedes-Benz modules.

With the M821 adapter, you can save as much as 65% of the calculation time, in addition to reducing the amount of times you’ll need to insert and remove the key emulator.

The M821 Mercedes-Benz Adapter is used for programming Mercedes-Benz EIS modules in an all-keys-lost situation. With the M821 adapter, you can save as much as 65% of the calculation time, in addition to reducing the amount of times you’ll need to insert and remove the key emulator.

When the M821 adapter and the KC501 IR reader/writer are combined, you can easily extract the EZS/ EIS key password which will allow you to program Infra-Red keys to DAS2/ DAS3 (FBS2/ FBS3).
