Hi Mark,

May I know the exact error that you see on the screen? Were you able to open the doors using the original key?

Can you still start the engine using the FOB?

Have you tried replacing the battery? If the battery never replaced from the time you bought the vehicle then it running weak that is why its not giving signal to the key.

Replace the battery and everything should be fixed. The battery model is CR 2032 battery.

Let me know if this helps.

Starting function is different from unlocking/locking the door. It doesnt mean that the battery is ok though you can unlock/lock the doors. Have you replaced the battery before?

If you haven't replaced the battery from the date you purchased the vehicle then I suggest you replace it first. This is our first step of the troubleshooting.

You will not see any pop up message when I posted my answer/message. You need to press F5 on your keyboard to refresh this page inorder to view/read my answer.

You its very odd as well that both keys will not start using the start function. Inorder for us to narrow down the problem. We need to eliminate the smallest possibility where the problem could start.

The first thing to start with is the batteries. Next step would be a the ignition module.

Please be informed also that there is a TSB for this issue since this is very common problem to this type of vehicle?

Have you called the dealership about the TSB regarding "damaged key" error?
Because the next step that you will do if new battery will not work is to bring the vehicle to the dealership and have them reprogram the key.

Let me know if you have questions.

Hi Mark,

Were you able to read my messages? Can you try to reset your vehicle first by unplugging both battery cables from the terminal. Wait for 2 mins then plug them back to the battery terminals. Test the issue again.

Let me know if this helps.
