Adding a smart key to your 2018 Acura CDX can be a straightforward task with the right tools. The Lonsdor K518ISE Pro is an ideal device for this job, providing an efficient way to program new smart keys. This process is especially useful when you've lost a key or need a spare.
Preparation
Before you start, make sure you have the K518ISE Pro device, an OBD communication cable, an original car key, and a new Lonsdor smart key ready.
Ensure that all components are present and that you have stable battery power in both the vehicle and the device, as programming interruptions due to power loss can affect the process.
Connecting to the Vehicle
First, connect the OBD communication cable to the vehicle's diagnostic port. This connection creates a communication bridge between the car's system and the K518ISE Pro.
Navigating the K518ISE Pro Menu
Once connected, navigate to the "Generate Smart" function on the K518ISE Pro. Select "ACURA," then "CDX," and proceed with the "first menu" option for key generation.
Place the new smart key into the card slot of the K518ISE Pro and initiate the generation process by clicking "Generate."
The device will confirm with a "Generation successful" message once the key is prepared.
Programming the Smart Key
After generating the key, switch to the "Immo&Remote" menu. From here, locate "ACURA," then choose "Smart Key" to begin programming.
Select the "Button 3" configuration as your key type and proceed with "Add a smart key." A prompt will confirm your selection.
Performing the Ignition Cycle
To program the new key, you'll be instructed to press the start button twice to turn the ignition on. This is a crucial step to ensure the vehicle recognizes the new key.
Remove all other smart keys from the car, keeping only the original inside. Next, insert the new smart key into the car.
You'll go through a cycle of turning the ignition off and on within 15 seconds a few times. Always check that the security light on the dashboard is off before proceeding.
Verifying the Programming
After completing the programming cycles, confirm that the K518ISE Pro shows the correct count of programmed keys. Test the new key for both start functionality and remote operations like lock/unlock.
With these steps, you will have successfully added a new smart key to your 2018 Acura CDX. Always ensure all safety and procedural checks are performed during the process to prevent any system malfunctions.
