Lonsdor K518 Pro Read 2023 Hyundai Santa Fe PIN Code and Add 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.

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.
