- Remote all doors unlock
- Remote all doors lock
- Remote search alarm
- Passive Entry
- Passive Lock
- Passive Start
- Backup Start
- Emergent mechanical Key
3.1.1 RKE Lock Key Fob Control
The RKE Lock command shall command the RKE_Lock_Request through a RF message to lock all the vehicle doors, by pressing the Lock Button.
3.1.2 RKE Unlock Key Fob Control
The RKE Unlock command shall command the RKE_Unlock_Request through a RF message to unlock all the vehicle doors, by pressing the Unlock Button.
3.1.3 RKE Searching vehicle Control
The RKE Searching vehicle command shall command the RKE_Search_Request through a RF message to start panic or stop searching the vehicle, by pressing the searching Button.
3.1.4 Passive Entry
The driver wants to entry the vehicle to press the door handle switch, and the KBCM ECU will send an authorization command to Smart Key via LF channel. And the Smart Key will give a response via RF channel. If the authorization is passed, and the smart key is not inside the vehicle, the KBCM ECU will open the door.
3.1.5 Passive Lock
The driver wants to leave the vehicle to press the door handle switch, and the
KBCM ECU will send an authorization command to Smart Key via LF channel. And

passed, and the smart key is not
inside the vehicle, the KBCM ECU will lock the door.
3.1.6 Passive Start
The driver wants to start the vehicle to press the SSB switch, and the KBCM ECU will send an authorization command to Smart Key via LF channel. And the Smart Key will give a response via RF channel. If the authorization is passed, and the smart key is inside the vehicle, the KBCM ECU will ask immobilizer base station to start engine.
3.1.7 Backup Start
When the Smart Key exhausted the battery, the Passive Start function will be
disabled. If the driver wants to start the vehicle, he shall take the smart
Key close to the SSB to press the SSB. And the immobilizer transponder
function of Smart Key will communicate with
immobilizer base station to start the engine.
3.1.8 Emergent mechanical Key

- Battery reversed installation protection
3.2.1 Switch Long Pressed Protection
In some case, the switch of the smart may be pressed for long time unintentionally. To avoid the battery was exhausted, the smart key will stop the RF signal transmission when the button has been pressed above 15s.
3.2.2 High Communication Security
The different SKCs for immobilizer and RKE&PKE guarantee the high
communication security.
The different encryption style for immobilizer and RKE&PKE increases the
communication security also.
3.2.3 Unique Wake Up Pattern
The unique wake up pattern for every vehicle decreases the battery consumption
for smart key and vehicle.
Also the wake up pattern can increase the communication security.
3.2.4 Battery reversed installation protection
The mechanical parts of smart key will protect the damaged for the reversed installation.
