I bought a second handed 2021 CX-3 couple of month ago. And the dealer gave me 1 original key fob and 2 spare ones.

The spare key looks just like below:


The spare keys can lock/unlock the door as expected and also can start the car from outside.

But the engine will stop as soon as the gear shift is switched to "D". Also, the engine will not start even I push the "start" button with the spare key.

Please share share you experience and let me know whether it is a key issue or just my operation is not correct.

Thanks in adv.
