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.

Generate 2018-2023 Camry 0351 Key with Autel IM508

 If anyone encountered the PCB 0351 -2018-2023 Camry.

Autel IM508/IM608‘s menu cannot generate under Camry option.
You have to go to CHR to get the right board number and it will still be under 0410 (0351).
And it will work perfectly.

In this case, generate remote under Toyota C-HR 2016-2024 314.35/312.10MHz, FSK ID8A, PCB 0410 option.

How to Add 2019 Citroen C5 Smart Key with Autel IM508?

 How to add a spare smart key for a 2019 Citroen C5 using Autel IM508?

 

First, create a key-type emergency key inside the smart key.

Turn the car door to make sure it opens and locks properly.

The key system is made of HU83 key blade and 7 bit.

You can open the car door by turning it towards the left bonnet.

The emergency key I made works smoothly on both the left and right.

Now, to register the new smart key you have prepared, connect Autel IM508 device to your vehicle’s OBD.

Connect the programmer to start communicating with the vehicle.

Autel will read 4-digit pin code.

You must enter the information correctly to proceed to the next item.

The slot location is a groove on the left side of the handle, so when registering the key.

You will need to register the key by contacting this section.

Even if the smart key battery is discharged, if you place the key in the car and press the start button as shown in the photo.

You will be able to start it.

If both the original key you currently have and the newly registered key are registered.

The number of registered keys is displayed on the scanner screen.

Add a smart key successfully

Both the original key and the additional key start the car normally.

We also test each remote control to see if it works properly.

Autel IM608 Program Volvo V40 2014 Semi-Smart Key via OBD

 User report:

It’s a Volvo V40 MK2 2014 with semi-smart key.

Add key with Autel IM608 fully via OBD, fast and easy.
Many beginners start the procedure by removing the CEM, which is not necessarily in this case.

Tranponder ID46 PCF7945A/Hitag 2
Programming: OBD
Excepton: Volvo V40 can be done directly via OBD (add key and AKL)
using Autel and other programmers (5 min)
Prepare dealer key: No
Remote: Automatic
If it’s keyless then obd won’t work. Only slot key.

V40 only can read fast, but others v70 or xc70 take 3-4 hours via obd or pull out the cem.

Autel IM608 Adds 2024 Subaru Forester Smart Key

 It’s a Subaru Forester 2024 European model with ID8A smart key, 433MHZ.

Add key with Autel IM608 in 30 minutes.

Generate key using XM38 smart key (xhorse 0520 075).

Or using the Autel ikey Toyota smart key.

Autel will add key to this model. All keys lost is not possible.

FYI:

Abrites will add key and do all keys lost for Subaru 8A. AVDI wll do AKL via OBD by “Smart System” reset.
