Free ECU Seed-Key Tool

Select the ECU, security level, insert the seed, then calculate the key


This seed-key generator tool is offered freely "as is" and no support is being offered with it.

The key you are generating might, or might not work, and might, or might not unlock, depending on what you intend to do.

It is not suitable for unlocking EEPROM read/write access in instrument clusters (for example, to activate the AMG menu, or mileage virginization).


Can also use just the plain seed, without the response bytes, or can use with or without spaces between, and with (as in DTS) or without commas. Can also paste the whole Vediamo seed response row.




Can be pasted as is - Will work in both DTS and/or Vediamo (or in the MBTools app)
