Question: What’s the difference between EoneBoss NK001 and HK001 key copy device? They all copy Hyundai /Kia NCF29Ax smart keys?

Here is the clue.

1. Vehicle Coverage 

HK001: for Hyundai and Kia only

NK001: for multile brands

2. Functions

HK001:

1). Generate Hyundai Kia smart remote

2). Copy Hyundai/Kia NCF29Ax smart key.

3). Unlock Hyundai/Kia smart keys

HK001:

Copy NCF29Ax smart keys for multiple car brands.

Both devices will copy Hyundai/Kia NCF29Ax smart keys. HK001 will do Hyundai/Kia only. NK001 cannot generate remote and unlock smart key. It only copy smart keys.

Problem:

Lexus GX 2023 all keys lost situation. The owner tried to back up immo data with Autel IM608 and g-box failed. Then he does reset immo box but when he tries add key, learning failed.

Error when back up immo data:
The current smart main ECU software version number is not supported.

Solution:

TMLF12-1 (FCC ID: NI4TMLF12-1) is a smart key immobilizer model manufactured by DENSO used in various Toyota and Lexus vehicles. It typically operates on a 314-315 MHz frequency and is used for 8A-type knife keys and push-button proximity systems.

As Autel said, this ECU software version is not supported by Autel IM508/IM608.

Try other devices.

User feedback:

Autel failed. Lonsdor K518 pro working fine.

Programmed by lonsdor reset immo.

VW Golf 7 2017 MQB – All Keys Lost is done with OBDSTAR X300 Classic G3.

It’s a keyed ignition and manual gearbox.
Obdstar did all.
Without 3rd part sync code.

Dashboard was read on bench using RH850 kit and DFLASH/PFLASH data extracted successfully.

New key learned successfully.

Problem:

During a BMW CAS3+ downgrade, the Yanhua Mini ACDP2 device froze and the operation failed. Now the CAS3+ (ISTAP) module shows no VIN or config options, and all keys are not working. I’ve heard of a ‘downgrade failure’ recovery option for CAS3, but it’s not showing up in the tool menu. Can Yanhua ACDP device repair this CAS module?

Solution:

Yes, Yanhua ACDP will repair BMW CAS3+ ISTAP module if downgrade failed and is corrupted.

Menu path:

IMMO Programming- BMW- CAS1 to 4- CAS3/CAS3+.
Select OBD Mode– IMMO Function.
Go to Special Function.

Choose ISTAP original repair.

NOTE: The repair is done via OBD mode rather than ICP mode. Connect the ACDP with the vehicle OBD port and make sure the vehicle has enough battery supply. DO NOT cut off power nor unplug the devce during the operation.

*ISTAP original repair and ISTAP downgrade repair are the same. Select original software version and repair the bricked module.

For CAS3+ istap, better do it via ICP mode using ACDP solder free adapter.  You will always be encouraged to pull cas and do it on bench.

Problem:

Trying to make a key for a 2019 VW Polo, Normal key not proximity. 5c chip. Tried using both adapters that are in the shape of the key. Lonsdor K518 failed to read original key data with the MQB49 5C adapter.

It reported an error “Data reading failed. Error code Unlock failed ret=25”. Any solution?

Solution:

Check the connection diagram carefully. You need to solder one wire from the key circuit board to the 5C interface board, as shown in the diagram. Then try again, and it should work.

Not for all key types. For this type of key, solder 1 wire to the board.

If reading the original key data for BMW BDC2 or BDC3 fails (error code 25), check if need to solder 1 wire to the board as well.

FYI: If your OBDSTAR P50/Odomaster/iScan scanners cannot turn on even when connected to a power supply,

Possible Causes:

• Battery is depleted.
• Mainboard failure.

Troubleshooting and Solutions:

1. Connect the device to the power adapter and check whether the power indicator light turns on.

If the indicator light shows red, this indicates the device is charging. Allow it to charge for at least 30 minutes before attempting to power it on again.

If the device powers on, the issue was caused by a depleted battery. Fully charge the battery to resolve the issue.

If the device still does not power on, the problem is not battery-related.

Remove the back cover, disconnect the battery cable, and power the device directly via the mainboard (using the power adapter). Check if the device powers on.

If it powers on, the battery is faulty and requires replacement.
If it still does not power on, the issue is unrelated to the battery.
After ruling out battery issues, the problem is likely due to a faulty Android mainboard. Replacement of the Android mainboard is recommended.

2. If the power indicator light does not turn on at all when the power adapter is connected:

Try connecting the device to a vehicle’s power supply using the OBD main cable. If the indicator light turns on and the device powers up, the power adapter is defective and needs to be replaced.

If the device still shows no response even when powered via the vehicle:

The Android mainboard is most likely faulty. Replace the Android mainboard first to eliminate this possibility.

If replacing the Android mainboard does not resolve the issue, the VCI (Vehicle Communication Interface) mainboard is likely defective and requires replacement.

Problem:

Tried to diagnose a  Hino truck 2011 using Launch X431 Pro3S+ smartlink HD diagnostic scanner, but autovin failed to decode vehicle information. Any idea?

Solution:

Heavy duty does not support AutoVIN feature. 

Need to select vehicle model and year manually.

If manual selection not working, do a firmware Fix and try again.

Problem:

The software (BMW V51.66) and firmware (V12.12) have been successfully installed on the Launch Creader 2.0 BBA diagnostic scanner. However, when actually connecting to a vehicle or scanning the VIN, the system immediately displays a “Firmware update failed” error message. Also attempted a factory reset, cleared the cache, and used a mobile hotspot to perform a “firmware repair,” but all attempts failed.

Solution:

The solution goes to other Creader series scanners with firmware V12.12 as well.

Solution for Launch CRP Firmware (V12.12) update failure:

If the firmware fix fails, please first download the firmware from the Update Center and then attempt the firmware fix again.

1. Connect to the network and access the Update Center.
2. Select the firmware file (V12.12) that needs to be re-downloaded, and click “Update” to initiate the download.

• DOWNLOADBIN_CRP_12XIV2_V2 (V12.12)
• Firmware upgrade (V12.12)
• Firmware upgrade Program (V12.12)
• DOWNLOADBIN_CRE_X_V2 (V12.12)

3. On the main interface, click “DATA,” then navigate to “Firmware Fix” and execute the Firmware Fix process.

As titiled, here comes a real user review on Meredes Benz W204 ESL emulator programming.

“CGDI MB for the Win.
Today I successfully programmed an ESL Emulator for a Mercedes Benz W204.
These modules are common for Failing disabling the vehicle from Starting. A popular solution to this problem is to Programme and install an ELV emulator.
By using the Data from the Ignition switch module (EIS) we can use that data to write the ELV.
Specialist equipment is required for this process and I’m just learning the (Ins and Outs) of the process and the tools. I’ve done one before using the OTOFIX IM1 with the G-Box.
I have to admit it’s really enjoyable learning things like this. From seeing the Red light go to Green and hearing that fake noise from the emulator of the steering lock operating and then for the car to start!”
