Extreme EZS Reader:

1. Hash

From H0 to H7 are the actual current key hashes for each Keys position.

2. Used or Block positions

“Used” is occupied key position and “Block” is a blocked key position, also known as “Disabled Key Track”.

3. Security

This field displays the SSID, Sonder and Serial number of the EZS. Also it has a field to paste the “Password”.

4. Type II

For some different EZS types in order to read the data we have to select this option – this option is only needed for later NEC type EZS such as W166, W176, W246, W117.

5. EZS Status

  • Initialized – EZS are initialized in factory;
  • Personalized – EZS has been Personalized, meaning that FBS Data has been written inside (Hashes, SSID, Password… );
  • Neutralized – EZS has been Renewed sometime in the past using some tool. Usually this is the case when an EZS has been taken from another vehicle, Renewed, then re-adapted to match the current vehicle;
  • TP Removed – This is Transport Protection. TP must be removed before personalization process begins;
  • Activated – This means EZS is Activated. When an EZS is “Activated” it can no longer be personalized;
  • Spare – This tells us that the EZS is a “Spare Part” EZS;
  • Last Key – The number indicates the last Keys Position Used;
  • Prev Key – The number indicates the previous Keys Position Used

“NOTE” There are 2 different types of EZS. 1.Series and 2.Spare. Series EZS are the original EZS that are installed during time of production inside Factory. Spare EZS are Replacement/Aftersales EZS.

6. Ezs Read Button

We use this Button to “Read EZS” Before you press this button you should enter (or paste) the EZS Password into the “Password” field, When working on some EZS you will be prompted by the software to Re-insert IR KeyTool to EZS to complete the collection of data. Please follow the on screen instructions from Software.

7. EZS Options

  • Personalize EZS Series – Used to Personalize a Not Activated Neutralized EZS that was originally installed to a vehicle during Production inside Factory;
  • Personalize EZS Spare – Used to Personalize a Not Activated Neutralized Replacement EZS/Aftersales EZS;
  • EZS Renew – Used to Renew an EZS. This function resets the EZS to its default values, a common reason to use this function is when you need to install a used EZS into another vehicle, after the EZS is renewed the Vin is unlocked and can be re-written, also the current mileage stored inside the used EZS will get reset to zero when renewed. The “Activated” status will also get reset to a “Not Activated” state, meaning that it is now again possible to “Personalize” the used EZS with the personalization data of the vehicle that you are intending to install the used EZS into. To use this function successfully it is necessary to insert the EZS;
  • Password and the Dealer Password into the fields provided within the Software. You can use our Extreme MB Tool Software to calculate these Passwords efficiently;
  • Check Password – Used to verify if the Password inside the “Password” field is in fact a true match with the EZS.

8. Personalize EZS Button

We use this Button to execute the option that has been selected within the “EZS Options” section.

9. Load FBS3 Dump 

We use this Button to load an FBS data dump that was read previously using EZS reader software.

10. W204/212 ESL/EMU

  • Personalize ESL – This option is used to Personalize a real NEC type ESL or it can also be used to personalize any W204/212 ESL Emulator that supports the standard W204/212 ESL Personalization protocol. To successfully use this function you need to insert the “EZS Password” and also the “Dealer password” into the fields provided within the software. You can use our Extreme MB tool software to calculate these Passwords efficiently;
  • Personalize EMU – This option is used to Personalize our Emulator. To successfully use this function you will need only to insert the “ESL password” into the field provided within the software. You can use our Extreme MB tool software to calculate this Password efficiently;
  • ReNew EMU – With our Emulator this option can be used to Renew Emulator and set it back to the default “OLD mode”;
  • Esl Status – Reads the Status of a real ESL via the EZS IR. Useful option to determine if a Real NEC ESL is 0xAA Blocked.

11. Do it

 We use this Button to execute the option that has been selected within the “W204/212 ESL/EMU” section.

ESL option:

This option will personalize a “Not Activated” OEM ESL or any after market Emulator that follows the standard ESL Personalization protocol.

Requirements: The field “Password” and the field “Dealer Pass” ** must be filled to use this function.

NOTE: EZS does not get renewed during this function. Here we perform exactly the same function as the dealers Blue     Workshop key.

**You can use our Extreme MB Tool Software to calculate this Password efficiently.

EMU option:

This option will personalize one of our Novel ESL Emulators. This is the fastest option, as it only requires the ESL Password.

Requirements: The field “ESL Pass” ** must be filled to use this function.

NOTE: EZS does not get renewed during this function. Here we use the EZS as a gateway to transfer the ESL Password to our   emulator.

**You can use our Extreme MB Tool Software to calculate this Password efficiently.

Extreme BE Key Programmer:

1. Read Key

By pressing the “Read” button we can read various information from the BE, EB, EA, A1 and other after market keys, such as the Key ID, Status, Firmware, Distance and remaining Life of the key. User can also read full Eeprom from these after market keys (Including Password).

2. Key Dump

This is where you will load the Key file to be written to the Key. We simply press the button “Write” and the software will ask you to select a file, at this point choose the Key file that you wish to use, click open and the software will ask you if you wish to write the Key in Crypto Write mode. We recommend not to use Crypto Write when working with aftermarket Keys, as not all after market Keys support this function.

However, Crypto Write mode must be selected when working with OEM renewed NEC Keys with status 21DF. When user selects “No Crypto Write” the software will write the aftermarket Key Eeprom using normal block write (Full Eeprom will be written) After writing the Key dump to the Key the software will ask you if you wish to “Activate Key” This option is here because when working with old HC05 EZS sometimes the after market keys will fail to activate in the EZS automatically. It is good practice to use the “Activate Key” option when preparing an after market key for one of these old HC05 type EZS.

3. Select

By pressing the button “ReNew” we can erase all the data inside the BE Keys Eeprom and give it a Renewed status “21DF” Some after market keys will get status “0000” after Renew, an example of this is A1 Keys. These 21DF and 0000 statuses mean that the key is now ready to be programmed via IR with Programmer.

For the X-Horse BE Keys we can also read and change the frequency of the remote control. We do this by pressing the button “Get Freq” This will display the current frequency mode of the Key. After this the user will have the option to “Set Freq” User can choose between the 3 different modes – FRE (Resistor controlled) 315Mhz and 433Mhz

4. Security

By pressing the button “Get” you can read the Password and the Current Hash direct from the after market keys such as the BE, EB, EA, A1 Keys all via IR.

Extreme EZS Password:


This field Displays the SSID of the EZS.

2. Sonder

This field displays the EZS Sonder Hash. Sonder Hash can be called different names depending on the tool manufacturer. It is good to understand that Sonder/Special and Service Hash are all same, only different terminology. Same goes for Dealer Password and Erase Password. From the Sonder you can calculate the Dealer Password needed to Renew EZS. You can calculate the “Dealer Password” using the Extreme MB tool software.

3. Password

Password: = This is the actual “True” EZS Password calculated and checked by our software, because we check the Password before it is displayed inside this field you can be 100% sure that it is a match with the EZS.

4. Enc. Pass

Enc.Pass: = Encrypted Password. When we see this Enc. Pass, this means that Password reading via IR is not supported on this EZS. The EZS has returned an encrypted response, we can only use this encrypted response to verify the true password if it is known.

5. Go Button

Pressing the “GO” button will start the process of reading the EZS Password Via the IR Portal. This can take up to 3 minutes to complete. HC12 types are usually finished within 50 seconds, whereas HC908 types can take up to 3 minutes.


**Read Password direct from EZS via IR. Support Old Motorola EZS with MCU’s HC908 and HC12 inside EG: Some W203, W463, W209, W211, W215. Not support HC05, ST12 or ZGW types.. Here is a list of tested Part Numbers: 2035450108, 2035450308, 2035450508, 2035450608, 2095450508, 2115450608, 2115451008, 2155450208, 2155450408

Extreme All Keys Lost:

1. AKL

When you select this option, it means that you will work with the “All Keys Lost” function within the software.


This field displays the SSID of the EZS.

3. Counter

Remaining data to collect during Data Acquisition.

4. Drop down Menu

Here we select the Car model for All Keys Lost procedure. Supported currently are the following models with FBS3 -> W176 -> A-Class (2012-2014) W246 -> B-Class (2012-2014) W166 – M/GLE-Class (2012-2014) W117 -> CLA-Class (2013-2014) W212 -> E-Class (2009-2013); W218 -> CLS – Class (2011-2014) C197 ->SLS-Class (2010-2014).

5. All Keys Lost Button

When you select the Checkbox “AKL” the text on this button is changed to “All Keys Lost” We click on it to begin the AKL procedure.

6. Ezs Pass

We can use this field to enter a Password to check if it is in fact a match with EZS. That’s mean this Password can be calculated using the Extreme MB tool software.

7. Check Password Button

When a password is entered into the “EZS Pass” field, the text on the button becomes “Check Password”. If you press the “Check Password” button the software will check if the password is a match with EZS.

8. Erase Hash

This is the field where we can enter the calculated Dealer Password if we want to “Renew the EZS”. We can calculate this Dealer Password using the Extreme MB tool software. When the software detects that there is a Dealer Password entered into the “Erase Hash” field and it also detects that an EZS Password is present inside the “EZS Pass” field, then we will see that the text on the button becomes “ReNew EZS” This button can now be used to “Renew EZS”.

9. ReNew EZS Button

You use this button to “ReNew the EZS”.
