When it comes to programming a new smart key for a 2012 KIA K5, tools like the Lonsdor K518 Pro are incredibly valuable. This guide walks you through the steps needed to add a smart key using this advanced key programmer, ensuring your 2012 KIA K5 is equipped with fully functional keys.
Preparation
Before getting started, gather the necessary components:
the Lonsdor K518 PRO device,
an OBD communication cable,
an original car key,
and a new smart key produced by Lonsdor.
Verify that you have a stable power supply and your vehicle is parked safely.
Connecting the Device
Begin by plugging the OBD communication cable into your KIA K5's OBD port. This step is crucial for establishing the connection between the Lonsdor device and your vehicle.
Key Generation
Navigate to "Generate smart key" on the K518 PRO. You'll start by selecting "KIA" and then look for the K5 model. Using your original car key, choose the first menu option and insert the new Lonsdor smart key into the card slot on the device to proceed.
After a loading period, you'll see a "Generation successful" message. Confirm and proceed to the main menu again by tapping "OK".
Navigating to Immobilizer Functions
Select "Immo & Remote" from the main menu, then choose "KIA". Specify the vehicle "China" model as "K5" for the 2011-2012 segment. This setup prepares you for programming the smart key.
Reading the PIN Code
The first critical step in programming is retrieving the PIN code. Choose "Read PIN code via OBD" to derive the code directly from the vehicle. Follow the on-screen instructions to turn off the ignition, open and close the driver's door once, and activate the hazard lights.
Upon completion, the K518 PRO will display the successfully retrieved PIN code.
Key Programming
With the PIN code in hand, proceed by selecting "Program smart key".
Press the start button, turn off the ignition. Follow the device instructions to insert the smart key into the car’s designated sensing area—typically located in the glove compartment or armrest box. Confirm the automatically entered PIN code to finalize the programming.

Insert first key into sensing slot
Success messages will confirm the programming of each key, with options to continue programming additional keys.
Testing the Keys
Finally, test both keys to ensure they function correctly. Start the vehicle and confirm the smart keys can lock and unlock the doors without issue.
By following these steps, professionals and advanced DIY enthusiasts can confidently add smart keys to their vehicles using the Lonsdor K518 Pro.
