Model example: VW Passat 1.4T year 2019 with MQB48 smart eky

 

Procedure:

Step 1: Read Vehicle Information

Go to Expert Mode- Key reading via dump- MQB48 (5A)

Read vehicle information.

Place a working key in the sensing area and turn on the ignition.
Read and confirm vehicle information.

 

Step 2: Recognize Key Info

Disassemble original key and remove the circuit board.

Select Recognize key information.
Connect APB300 programmer with Autel IM508/IM608 via USB port.
Place the working key into the recognition area of the APB300 for recognition.
Communicating with the key. The green light on the APB300 will turn on.
Read key ID.

Take a screenshot of the original key ID.

 

Step 3: Calculate IMMO Data

Select Calculate IMMO Data function.

Autel will ask if you want to add an original key or an Autel key.
If you use Autel key, you need to verify it is the Autel key. Autel key allows you to calculate immo data for free.
If you use the original key, it is based on pay-per-use.

Place the Autel standard smart key to APB300 coil and verify it is an Autel key.

Autel will show you key wiring diagrams.

Select one that matches your MQB48 key.
The supplied terminal wire should be welded when prompted by the on-screen instructions on the tablet.

Place the original circuit board into APB300 programmer.

Autel IM508 Peugeot 4A Smart Key Not Start Solution

We would like to share an issue and its solution regarding a 2022 Peugeot 208 4A smart key failing to start the vehicle after key programming. We hope this helps others who encounter the same problem.

 

Problem:

2022 Peugeot 208 smart key 4A tried to add a key with Autel MaxiIM IM508 key programmer. Everything went smoothly, read pin ok and add smart key. It said to turn off emergency indicators after 30 minutes. Did add key 30 min and both keys stopped working. Both keys won’t start.

Solution:

After programming key there’s a 30 min wait before you can start car, wait until hazard stop flashing before trying to start.
30 min waiting time. common on those vehicles just wait.

Autel worked well. He got pin code, pin code is good because he erase original keys (he enter in programmong procedure), and he didn’t program any key to car (because that hazard lights iliminate constant, because there is no any key programmed).
He missed spot for key programming, or key sense area is not working.

Added AKL key 30 min waiting with the turn signals that turn on itself.

 

Feedback:

Came back the next day and went to control unit and keyless system(can). Added another keydiy zb smart key. Did learning for the proximity functions once the key was added on the sense area by holding the lock button for 10 seconds.

Autel IM508 2021 Jeep Programming BOOT2 Error?

Problem:

Tried to add a spare key to a 2021 Jeep Compass with Autel IM508.

This is what I am getting, trying to read password it keeps.

Error: Programming BOOT2

Any solution?

Solution:

Voltage is low.

Connect battery booster or change battery.

Battery is dead on that car, get a battery maintainer as at 9V no modules will talk and you risk damaging the car. For any sort of programing 13.5V is a must.
If you use correct booster, you can set to 13.5V or more.

 

Feedback:

The car had a problem, electrical problem. The battery was good, but the voltage was showing low. I ended up figuring it out and got the job done. I had noticed the voltage but when I hook up to the battery, it will show 12.5 but on the scanner, it shows 8。

Autel IM508 Failed to Read Toyota CHR 2021-2023 IMMO Data Solution

Problem:

It also happens on 2021-2023 Toyota CHR with 8A proximity key. It’s all keys lost situation, tried AKL smart box reset using Autel IM508S but failed. The smart box has 27 PIN connector so the 30 PIN cable will not fit.

Tried with gbox3 on bench, get message informing that this software version number is not supported.

“The current smart main ECU software version number is not supported.
Version number: 8999AF4120010101”

Solution:

IM608 and IM508 don’t able to read latest tmlf15-3 smart box. Software version does not support.

Use other programmers. Autel does not support this version on smart key module.

If you use Autel for this, need to go straight to key learning , to get Incode/outcode pin code request procedure (buy 12-digit PIN).

Use Lonsdor K518 Pro , AVDI or Smart Pro.

Lonsdor K518 Pro: Try to back up immo data via OBD. If fails to back up immo data via OBD, back up data via ADP15 adapter. Generator emergency key than use immo data to program new key.

Smart Pro: use a Smart Pro with the key emulator adapter.

Autel IM608 Program 2023 Toyota Tundra All Keys Lost with FP30 Cable

This guide walks you through the process based on a real-world all-keys-lost scenario on a 2022 or 2023 Toyota Tundra (applicable to models up to 2025).  With the right tools and procedure, you can bypass the PIN code requirement and program new smart keys.

 

Tools used:

Autel MaxiIM IM508 or IM608

Lonsdor FP30 bypass cable (30 pin gateway connector)

APB112 emulator

New key to be programmed

 

Procedure:

Step 1: Access the Smart Box

Start by removing the plastic trim panel near the smart box. Once exposed, locate the second box next to the silver unit. You will see a top connector on that box — this needs to be disconnected.

Step 2: Connect the Bypass Cable

After disconnecting the original connector, plug in your bypass cable. This allows you to communicate directly with the smart box without requiring the original key or PIN code.

Step 3: Back Up EPROM Data

Using your Autel IM608 tool, perform a full backup of the EEPROM data. This is a critical step. Save the file securely.

Step 4: Generate an Analog Key (APB112 Emulator)

With the backup complete, generate an analog key using your software. Load the saved backup file, then connect your APB112 emulator (adapter). The emulator mimics a valid key and allows the vehicle to recognize a new key during programming.

Step 5: Reconnect the Original Connector

Once the emulator is connected and recognized, unplug the bypass cable and reconnect the original connector back into the smart box. This restores normal communication while keeping the emulator active.

Step 6: Verify Ignition Activation

Turn on the ignition using the emulator. The system will ask whether the ignition turned on. Confirm “yes.” This step ensures that the vehicle’s electronics are responding correctly.

Step 7: Add the New Smart Key

Navigate to the “Add Smart Key” function in your programming tool. The vehicle’s VIN will appear automatically. Confirm it, then hold the new key near the start button or as instructed by your tool. You should hear two beeps, and the tool will display “Succeeded.”

Step 8: Perform Steering Lock Synchronization

Even after adding the key, the steering lock may not sync automatically. Go to the steering lock sync function in your tool. Turn on the ignition when prompted. The tool will read the PIN code from the backup and complete the synchronization.

Step 9: Test Key Functions

At this point, test the remote functions. The key should lock and unlock the doors.

Step 10: Final Vehicle Start Check

Before calling the job complete, ensure the vehicle can start. In the example, the truck initially wouldn’t start because the transmission was left in Drive. Always make sure the shifter is in Park or Neutral before attempting to start. Once corrected, the vehicle started normally.
