In the world of automotive diagnostics and key programming, tools like the Lonsdor K518 Pro are invaluable. These devices offer comprehensive services that can save both time and money when adding new keys to vehicles. Today, we'll guide you through the process of adding a new smart key for a 2019 Geely Emgrand GL using such a tool.
Preparation
Before you start programming, ensure you have all necessary components:
- The Lonsdor K518 Pro device
- An OBD communication cable
- A new smart key to program
- The original car key for verification
Begin by plugging the OBD cable into the car's OBD port, which is usually located beneath the dashboard but can vary slightly depending on the vehicle model.
Navigating the Menu
Once the device is connected, power on the Lonsdor K518 Pro and select "Immo & Remote" from the main menu. From there, navigate through the car brands and select "Geely," followed by "Emgrand."
Since this particular Emgrand GL model uses a 1.4T engine, you'll need to choose "GL 1.4T" and then "PEPS," which is specific to this vehicle's system.
Key Programming Procedure
To initiate the key programming, select "Program key" and confirm your choice. The device will begin calculating the PIN code.
Next, select the third group from the list of ESK codes. This selection is crucial as it aligns with the vehicle's security protocols.

When prompted about deleting working keys, click "Cancel" to prevent any issues with the original key. Proceed by choosing to program "1 key" and follow the on-screen instructions.
The device will instruct you to place the new smart key in the car's induction area—usually the central console or between cup holders near the handbrake.
Ensure all other keys are more than two meters away to avoid interference during programming.
Finalizing the Key Programming
Once these steps are completed, the Lonsdor K518 Pro will display "Programming complete." Confirm this by clicking "OK."
Post-Programming Verification
To ensure everything is functioning correctly, test both the new and original keys by using them to start the vehicle and operate the remote locking functions.
The new key should start the car when you step on the brake and press the start button, and the remote should lock and unlock the vehicle smoothly.
Verify the same functions with the original key to ensure all previous programming remains effective.
By following these steps with the Lonsdor K518 Pro, you can confidently add a new smart key for a 2019 Geely Emgrand GL without issue.
