How to Add 2021 Lada Largus Key with Lonsdor K518 Pro

 It is a 2021 Lada (VAZ) Largus, a Russian vehicle.

The task is to make a duplicate key. 2021 is a transitional year for this car and starting from 2021, these cars use a different type of BCM and, as a result, a different type of key. All this complicates the programming procedure and if the programming is incorrect, there is a risk of getting real estate instead of a car (relevant for all new Lada cars from Vesta onwards).

Device used: Londsor K518 Pro.

So, the order of actions:
1. Cut the blade on the new key.
2. Read the pin from the bcm block, observing all the precautions.
3. Learn all the keys.

Add Fiat Talento 2021 Smart Key by Lonsdor or SmartPro

 Question: 

Adding a spare smart key to Fiat Talento 2021. Which device is better Lonsdor K518 Pro or SmartPro.

Lonsdor K518 pro comes up with this when attempting to read pin. It takes 1 hour to access. While Smartpro takes a few minutes.

Add Fiat Talento 2021 Smart Key by Lonsdor

Why SmartPro is so fast?

It is not bypass the pin code. It actually makes UCH virgin and while in that state, it read PIN And then re-learn UCH with original working key.

It virginize UCH which allows then to read PIN without long procedure to read / write flash data. That’s how ‘Quick method’ works in Smart Pro.

It’s same method as Renault ECU Tool works with 2016+ Clio 4 / Captur.

 

For example:

Add Talento 2021 key with Smart pro using Xhorse XS MQB remote.

Need power supply support.

Add Fiat Talento 2021 Smart Key by smartpro 2

Add Fiat Talento 2021 Smart Key by smartpro 3

Add Fiat Talento 2021 Smart Key by smartpro 4

Which tool to use?

Of course Trafic / Talento is different system than Clio IV but you can also use 2 methods of doing that. Long method read and write flash and same Quick method like ECU Tool and SmartPro does.

For Trafic / Talento, the long method Read/Write flash is safer than the fast Smart Pro method because you have backup.

If somehow the tool will not read PIN code in UCH / HFM virgin state, then you have bricked car which needs online reprogramming.
If you use long method, you have backup. Lonsdor has 2016- Talento menu, for 2021 model, it needs luck.

SmartPro also has long method. Always have battery maintenance. It’s very important. It is risky on those.

Lonsdor FT02 PH0440B vs Lonsdor LT20 Smart key

 What is the major difference from the Lonsdor FT02 PH0440B 8A+4D and LT20 8A+4D prox boards? When I read both specifications, they seem the same.

Lonsdor LT08

Lonsdor LT20

FT08-PH0440 is a Lonsdor’s copy key that you can use their Toyota AKL software and copy a key from the existing keys in the system by sniffing through the push start button. You can also clone over it from an existing working key but remote RKE function will not work on both keys at same time.

LT-20 boards are their new boards that you can use as an emulator to turn ignition on also you can precode it with proper P4 value and frequency to make a programmable key to the car. So you program it as if you were programming a normal key.

Program 2024 Nissan Rogue Smart Key with Lonsdor K518 Pro

Programming a smart key for a modern vehicle like the 2024 Nissan Rogue might seem daunting, but with the right tools and a bit of guidance, it can be a straightforward process. In this article, we’ll walk you through the steps to program a smart key using the Lonsdor K518 Pro and a 40-pin BCM adapter.

 

Tools and Equipment Needed:

 

Step-by-Step Guide:

1. Accessing the BCM (Body Control Module)

The first step in the process is to access the BCM, which is located behind the side panel in the driver’s footwell. Here’s how to do it:

  • Remove the side panel: The panel can be snapped off by hand. There’s a small torque screw inside the footwell that requires a T15 Torx screwdriver to remove. Once the screw is out, the rest of the panel can be easily snapped off.
  • Locate the fuse box: The fuse box covers the BCM. There’s a small plastic tab on the fuse box that can be pushed in with your finger, allowing the fuse box to slide out.
  • Access the BCM: The BCM is a black box mounted on a bracket with two 10 mm screws. Remove these screws and slide the BCM forward to expose the connectors.

2. Connecting the 40-Pin Adapter Cable

  • Unplug the gray 40-pin cable: This cable is connected to the BCM. Unplug it and connect it to the 40-pin adapter harness.
  • Reconnect the adapter: Plug the other end of the adapter harness back into the BCM.
  • Connect the DLC connector: The adapter harness will have a DLC (Diagnostic Link Connector) that you’ll plug into your Lonsdor K518 Pro. The other end of the DLC connector should be plugged into the vehicle’s DLC port.

3. Programming the Smart Key

Once everything is connected, you’re ready to program the smart key. Here’s how the process works:

  • Turn off the ignition: Ensure the vehicle’s ignition is turned off.
  • Turn on the hazard lights: This is part of the programming sequence.
  • Follow the prompts on the Lonsdor K518 Pro: The device will guide you through the process. It will ask you to hold the original key up to the start button to verify the chip. The device will then connect to the internet to perform the necessary calculations.
  • Program all keys: The system will erase all existing keys, so it’s important to have all keys (both existing and new) present during the programming process. The Lonsdor K518 Pro will prompt you to hold each key up to the start button to program it.

4. Completing the Process

  • Verify the new key: Once the programming is complete, the new smart key should be fully functional. You can test it by locking and unlocking the vehicle or starting the engine.
  • Copy the key blade: If your new smart key came with a blank blade, you’ll need to cut it to match the original key. This can be done using a key-cutting machine.

Tips and Considerations:

  • Internet Connection: Ensure you have a stable Wi-Fi connection during the programming process, as the Lonsdor K518 Pro needs to connect to the internet for certain calculations.
  • All Keys Present: Remember that the system will erase all existing keys, so you must have all keys (old and new) with you during programming.
  • Compatibility: While this guide uses the Lonsdor K518 Pro, other programmers like the Autel IM508OBDSTAR or Advanced Diagnostics tools should also work, as long as they support the Nissan 40-pin BCM cable.

Conclusion:

Programming a smart key for a 2024 Nissan Rogue is a relatively simple process when you have the right tools and follow the correct steps. The Lonsdor K518 Pro, combined with the Nissan 40-pin BCM adapter, makes the job quick and efficient, taking only a few minutes to complete. Whether you’re a professional locksmith or a DIY enthusiast, this guide should help you successfully program a new smart key for your Nissan Rogue.

Lonsdor K518 Pro Adds 2023 Hyundai Santa Fe Smart Key

 This article will walk you through the process of programming a smart key for the 2023 Hyundai Santa Fe using the Lonsdor K518 Pro, a tool that has proven to be reliable for such tasks.

Lonsdor K518 Pro Adds 2023 Hyundai Santa Fe Smart Key 1

The Challenge with New Hyundai Keys

This particular job was the third Hyundai I had worked on in a week, with the other two being a 2022 Santa Fe and a 2023 Tucson. Both vehicles presented their own set of challenges, particularly when it came to programming and pulling the PIN codes. For the 2022 Santa Fe, I used the Auto Pro Pad to retrieve the PIN, while for the 2023 Tucson, I had to obtain the PIN directly from Hyundai. These experiences highlighted the importance of having the right tools and knowledge to tackle different scenarios.

Setting Up the Lonsdor K518 Pro

For the 2023 Santa Fe, I decided to use the Lonsdor K518 Pro, the same tool I had successfully used for the previous two vehicles. The process began by accessing the “Immo and Remote” section on the device and selecting Hyundai from the list of manufacturers. The next step was to read the PIN code (Read pin ID47 smart key), which is essential for programming the new smart key.

Reading the PIN Code

After selecting the appropriate model (in this case, the 2023 Santa Fe), the Lonsdor K518 Pro prompted me to turn the ignition on and off, open and close the driver’s door, and activate the hazard lights. These steps are designed to keep the body control module active, which is necessary for the device to communicate with the vehicle’s system. Despite some initial hiccups with the Wi-Fi connection, the device successfully pulled the PIN code after about 25 seconds.

Programming the Smart Key

With the PIN code in hand, the next step was to program the new smart key. It’s important to note that when programming new keys, all existing keys must be present, as any keys not programmed during this process will be erased from the vehicle’s system. In this case, the customer provided two keys, both of which needed to be programmed.

The Lonsdor K518 Pro guided me through the process, prompting me to confirm the PIN code and then prepare each key for programming. The device instructed me to press the start button within five seconds of confirming the PIN, and after a few moments, the first key was successfully programmed. The same process was repeated for the second key, which also programmed without any issues.

Testing the Keys

After programming, it’s crucial to test each key to ensure they work correctly. In this case, both keys were able to lock and unlock the vehicle, and the rear hatch opened as expected. While I didn’t test every feature of the key (as the customer had supplied the key itself), the primary functions worked perfectly, indicating a successful programming session.

Conclusion

Programming a smart key for a 2023 Hyundai Santa Fe using the Lonsdor K518 Pro is a straightforward process, provided you have the right tools and follow the steps carefully. This job was another win for the Lonsdor K518 Pro, which continues to prove its reliability in handling modern vehicle security systems.
