Tango Key Programmer Writes Megamos 48 CS Confirmed!

This an original Scorpio-LK Tango Key Programmer help file.

Purpose: write Megamos 48 component security
Component Security in Megamos 48 key

The modern immobilizers of the VAG-group vehicles have such conception as “Component Security” (CS). The CS is an array of 7 bytes length. Its role in a vehicle is to forbid a mixing of electronic units from different cars. In terms of the immobilizer the CS is a “password” that used in couple of the Motor Unit (ECU) and the immobilizer.

The protection scheme includes 3 components that share the CS, they are: ECU

IMMO KEY

The protection scheme allows the engine to start only in case when the CS is identical in all the three components.

Key and CS

The CS is a part of the Crypto Key and fills its upper area Word9-Word6.

ECU and CS

ECU uses the CS as a password. More modern ECUs contain only 6 bytes of the CS. In this case the CS should be extracted from another devices, for example it may be a dashboard.

IMMO and CS

The vehicle dashboard usually has a role of an immobilizer. The IMMO always contains all the 7 bytes of the CS.

The Tango key programming tool “Write Component Security 7 Bytes” (Megamos 48 window) helps you to put the CS manually into a transponder.

Example of ECU BOSCH Motronic M7:

ECU dump, eeprom 95040:

tango-writing-megamos-cs

The CS has been marked in the blue color.

To write the CS, invoke the tool and type the CS in the window:

tango-write-megamos-cs

Select the vehicle brand and press the Write button.

Temporary the Seat brand is unavailable.

These devices support old BMW motorbikes with 46 chip only.  None will write a 4D70 chip key.

Last Try:
Finnaly I was told by some motorcycle experts,  the TMPro2 (Transponder Maker Pro) is a motor beast.

Directly connect device with laptop via USB port, don’t need extra power supply.
Software is multi-language available (Bulgarian, English, French, Portuguese, Polish, Hungarian, Spanish, Serbian, Italian, Czech, Chinese, Greek, Turkish and Romanian). Here I tested the Chinese version.

There are 211 software modules available currently, including 38 Motorbike modules.

It is said that it is THE ONLY tool in the world that can make key for keyless BMW motorbikes.

Device does come with some FREE functions:  read chip information, read and write EEPROMS 93cXX, 24cXX, 25cXXX, 95cXXX, S29190, X5328, Motorola 912 / 9S12, Microchip PIC18F252, read Motorola HC805P18 (need adapter), unlock Megamos Crypto ID48 chip and change mileage on BMW CAS FEM/BDC.

Program-New-Key-on-a-BMW-R1200GS-2015-Motorcycle-11

It can still used as a chip programmer if don’t buy any software module.

There are several BMW motorbike modules depends on years.

For R1200GS, you need to purchase module 191.
For BMSX or BMS2K or BMSMP ECU – to see where keys are stored you must check what is on ignition barrel.
If there is IMMOBOX UNIT – keys are stored in this unit but not in ECU.
