Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, screwdriver set, replacement battery, cleaning cloth.
Ensure the vehicle is parked and the ignition is off. Disconnect the battery if necessary for safety.

2. Replace Remote Key Fob Battery

Open the remote key fob using a small flat screwdriver to pry apart the casing.
Remove the old battery and replace it with a new battery (typically CR2032 or as specified in the owner’s manual).
Reassemble the key fob and test the remote function.

3. Inspect and Clean Key Fob Contacts

If the remote still does not work, open the fob again and inspect the internal contacts for corrosion or dirt.
Clean any contacts using a cleaning cloth or isopropyl alcohol.
Reassemble and test the remote again.

4. Reprogram Key Fob (if necessary)

If the fob still isn't responding, refer to the owner's manual for the programming procedure specific to the Genesis G70.
Follow the provided steps to reprogram the key fob, which usually involves turning the ignition to the "ON" position and pressing buttons in a specific sequence.

5. Test Door Lock Actuators

If the remote still does not work, check the door lock actuators by applying power directly to them to ensure they engage and disengage.
If they do not respond, they may need to be replaced.
