Adds Add Key function for BDC03 immobilizer for the following models with G chassis:
[Major upgrade]
2 Series G42/G87 2020-2024
3 Series G20/G21/G28/G81/G80 2020-2024
4 Series G22/G23/G26/G82/G83 2020-2024
5 Series G30/G31/G38/G60 2020-2024
6 Series G32 2020/07-2024/06
7 Series G11/G12/G70 2020-2024
8 Series G14/G15/G16 2020-2024
X3 G01/G08/G45 2020-2024
X4 G02 2020-2024

 

NOTE:

We still need to pay BMW G-chassis subscription to add BDC3 key.

It is getting immo from key not from BDC3 module. It is safer.

Need to add an Autel BMW ikey universal smart key.

The current function only supports adding keys for some BDC3 models, not all.
For keys with model years between 2020-2024 and the “Hungary” marking in the upper right corner, the success rate is higher.

Main steps to add BMW G Series BDC3 Key with Autel:

Go to Smart mode- scan BMW BDC3 immo module- select Add key function.

Step 1: Read vehicle info
Step 2: Read key data
This step requires disassembling the original key and reading data from original key.

There are 3 ways to connect the key board with xp400 pro:

1. Use the APB113 adapter (it is included in the IMKPA kit) to connect the key to the xp400 programmer.

2. Use a wiring harness to connect the key to the xp400 programmer.

3. Use a solder-free clip to connect the key to the programmer.

It is recommended to use the APB113 adapter for more stable data reading.

Then connect the apb113 adapter to the xp400 pro to read key data.

Step 3: Generate dealer key
This function only generates Autel BMW ikey.
Place the Autel BMW ikey to the coil of XP400 Pro like this.

Then start generating key.

Autel IM508 Adds Mazda CX-50 2023 Smart Key

 2023 Mazda Cx-50 add key successfully with Autel IM508.

Autel Im508 under cx-30 (add key guided) will read P Flash, calculate passcode and add key. Use aftermarket key.

There was no cx-50 option and auto identify failed. But going under cx-30 worked liked a charm.

Program Mazda CX-5 2024 Smart Key by Autel IM508

 Anybody done a 2024 Mazda CX-5 Add key using Autel IM508? Does it need any additional equipment?

Here is the clue.

For CX-5 before 01/2022, Autel, OBDSTAR and SmartPro devices will add key without pin code.

For example:

2021 Mazda CX-30 new key added with autel im508s. It took around 15-20mins. Used aftermarket OEM looking key – no key error on cluster. Battery support required.

 

For 06/2022+, it depends if the software on the vehicle has been updated if car has been to dealer recently. Still 50/50.

If the car has not been updated at dealer,

Autel: Yes, Autel can do it. It will require incode/outcode. You should get a pin from NASTF and it would/may still leave the security light on.

When you use an Autel/Xhorse universal key will have the immo light on unless you copy the key ID from the working key. A cheap aftermarket key will cause the light also. Use OEM only. Also make sure you maintain the battery while programming.

Smart Pro:

According to Silca SmartPro can do it. smart pro bypass the incode on 2023. They have listed it up to 2024. 2024 model you still need to get the pin code.

Smart pro bypass the incode on 2023.

OBDSTAR:

OBDSTAR G3 now supports both add key and all keys lost for 2018-2024 CX-5, requiring pin code.

Example: OBDSTAR G3 program CX-5 2024 all keys lost via OBD.

If the car has done dealer updates, do it with MDRS dealer software and pin with NASTF.

If it is 2024 Mazda CX-90, it is similar to CX-30. It should be done via MDRS with pin code.

 

There is another way to make a new key to CX-5 if it has ID6A proximity key. You can clone 6A smart key using Xhorse key tool max.

It works. but the safe way is to clone an aftermarket key to xhorse XM38 smart key, not clone original key to xhorse key.

4. Adds IMMO functions for the following models of Buick: Envision (2025), Encore GX (2025), etc.

5. Adds IMMO status scan and guided functions for models as of 2020.

6. Adds VIN decoding function for certain new models.

7. Optimizes IMMO functions for certain models.

It doesn’t say it reads code. Autel has always been able to do them when you get the code from 3rd party.
They added the programming function for newer models till 2025, you will still have to get pin code from 3rd party.
It’s always just been easier to use sps2
and the 2 hour wait is still there with code from 3rd party.

How to Unlock Benz NEC Key V57 with Autel IM508 & APB115?

 Unlocking and reusing a Mercedes NEC Key Chip V57 can be a cost-effective solution for repurposing a key for another vehicle. This process involves desoldering the chip, erasing its data, and reprogramming it for a different car. Below is a step-by-step guide based on the provided instructions.

Tools used:

Autel IM508

APB115 adapter

Step-by-Step Guide

1. Opening the Key Fob

• Use a sharp tool to carefully lift the sides of the key fob.

• Gently pry open the casing to reveal the internal components.

• Remove the batteries located at the back.

2. Removing the NEC Key Chip

• Locate the white tab inside the key fob.

• Pull the tab upwards to release the chip from its housing.

• The NEC Key Chip (V57) will now be accessible.

3. Desoldering the Chip

• Identify the orientation of the chip, noting position number one (mark it with a pen or marker for reference).

• Carefully desolder the chip from the circuit board using a soldering iron.

4. Erasing and Reprogramming the Chip

• Transfer the desoldered chip to an APB 115.

• Use the device to erase the existing data on the chip.

• Once erased, the chip can be reprogrammed for use with another car.

5. Reassembling the Key

• Solder the chip back onto the circuit board, ensuring correct orientation (refer to the marked position).

• Reinsert the chip into the key fob and secure the casing.

• Replace the batteries and test the key.

Conclusion

By following these steps, you can successfully unlock and renew a Mercedes NEC Key Chip V57 for another vehicle. This method saves money and reduces waste by reusing existing components. Always handle electronic components with care and ensure proper tools are used for desoldering and reprogramming.

Autel IM508 Read VAG EDC17C64 ECU and Decode CS Code

 Working with Volkswagen Group (VAG) ECUs, such as the EDC17C64 found in the Golf 7 2014, requires precision and the right tools. In this guide, we’ll walk through the process of reading EEPROM and flash data, extracting the CS code, and getting synchronized data for key programming or ECU cloning—using the Autel IM508 XP400 Pro and GBOX 3 tool.

 

Step-by-Step Process

1. Establishing Connection

• Connect the ECU with Gbox3 and IM508 according to the wiring diagram in the IM508 (green light indicates a good connection).

• Power the ECU with 12V to avoid communication drops (listen for relay clicks).

2. Reading EEPROM Data

• Select “Read EEPROM” in the software.

• The process is fast (takes seconds) and extracts critical immobilizer data.

• Save the file immediately for backup.

3. Reading Flash Data

• Flash reading is slower (15+ minutes) but essential for synchronization.

• Save the flash file once completed.

4. Decoding CS to get Sync Data

• Select EDC17/MED17/ME17 data processing function.

• Load both EEPROM and flash files into the software.

• Click “Decode” to extract:

  • CS (Component Security) Code (required for key programming).

  • VIN Number (verification).

The steps above is how to read ecu data from ecu to get sync data with instrument cluster.
