The Key Fob also contains the Remote Keyless Entry (RKE) transmitter and an emergency key, which stores in the rear of the Key Fob.
The emergency key allows for entry into the vehicle should the battery in the vehicle or the Key Fob go dead.
You can keep the emergency key with you when valet parking.
To remove the emergency key, slide the mechanical latch on the face of the Key Fob sideways with your thumb and then pull the key out with your other hand.
