Gen III Prius Smart Key Entry System
1. SMART KEY SYSTEM DESCRIPTION
- This system is controlled by the certification ECU (smart key ECU assembly). When the certification ECU (smart key ECU assembly) detects the presence of the smart key system in one of the detection areas, it identifies and checks the ID code, and outputs operation signals to the related ECU in accordance with their functions.
- The detection areas are formed by 6 oscillators (2 door oscillators, 1 outside oscillator and 3 indoor oscillators).
(a) w/ Entry System Back Door Open Function
|
Actuation Area |
Detail |
|---|---|
|
Interior |
The interior detection area of the indoor electrical key oscillators (for front, center and rear floor) is formed when the driver door is opened or closed, when the power switch is pushed, when a warning is activated, or when the lock sensor on the door outside handle assembly or lock switch on the back door opener switch assembly is on. |
|
Exterior |
The exterior detection area formed by the door electrical key oscillators (for driver side and front passenger side) and outside electrical key oscillator (for rear side) is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the door outside handle assembly of the front doors, or the center of the rear bumper. |
|
Around Front Door |
The exterior detection area of the door electrical key oscillator (for driver side or front passenger side) is formed by transmitting a request signal every 0.25 seconds while the power switch is off and each door is locked. In this way it detects the proximity of a key. When locking the door using the lock sensor on the door outside handle assembly, the detection area is formed when the lock sensor is touched. |
|
Around Back Door |
The exterior detection area of the outside electrical key oscillator (for rear side) is formed by when the back door opener switch assembly (opener or lock switch) is on. |
(b) w/o Entry System Back Door Open Function
|
Actuation Area |
Detail |
|---|---|
|
Interior |
The interior detection area of the indoor electrical key oscillators (for front, center and rear floor) is formed when the driver door is opened or closed, when the power switch is pushed, when a warning is activated, or when the lock sensor on the door outside handle assembly or lock switch on the back door opener switch assembly is on. |
|
Exterior |
The exterior detection area formed by the door electrical key oscillators (for driver side) is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the door outside handle assembly of the front doors, or the center of the rear bumper. |
|
Around Front Door |
The exterior detection area of the door electrical key oscillator (for driver side) is formed by transmitting a request signal every 0.25 seconds while the power switch is off and each door is locked. In this way it detects the proximity of a key. When locking the door using the lock sensor on the door outside handle assembly, the detection area is formed when the lock sensor is touched. |

|
Function |
Outline |
|---|---|
|
Wireless Door Lock Control |
This function is a convenient system for locking and unlocking all the doors and back door at a distance. The operation of this function is the same as that in the wireless door lock control system. |
|
Entry Unlock |
When a key is in the exterior detection area of any door electrical key oscillator, the door will unlock after the inner side of either front door outside handle assembly (for driver side or front passenger side*) is touched.
|
|
Entry Unlock Mode Switching |
This function allows switching between 2 modes that can be operated with the entry unlock function.
|
|
Entry Lock |
|
|
Entry System Back Door Open Function* |
When a key is in the exterior detection area of the outside electrical key oscillator (for rear side), the back door opens manually by simply pressing the back door opener switch assembly (opener switch). |
|
Prevention of Key Confinement |
The key confinement prevention function prevents the vehicle from being locked with a key left inside. |
|
Warning |
When any of the situations below occur, the smart key system causes the certification ECU (smart key ECU assembly) to sound the buzzer in the combination meter assembly and wireless door lock buzzer assembly, and indicate a warning on the multi-information display in order to alert the driver:
|
|
Battery Saving |
If the key remains within the exterior detection area of any electrical key oscillator (for driver, front passenger or rear side), the system maintains periodic communication with the key. Therefore, if the vehicle remains parked in that state for a long time, the key battery and the vehicle battery could be drained. |
|
Key Cancel |
The following key functions can be cancelled by following certain procedures:
|
|
Key Code Registration |
A total of 7 keys can be registered. This function enables the registration (writing and storing) of transmitter recognition codes in the EEPROM that is contained in the certification ECU (smart key ECU assembly). |
*: w/ Entry System Back Door Open Function
6. WIRELESS DOOR LOCK CONTROL SYSTEM FUNCTION
Push the lock/unlock/panic/remote A/C* switch on the key to operate each function.
*: w/ Remote Air Conditioning System
7. ENTRY UNLOCK FUNCTION
(a) When the key enters any exterior detection area of a front door, the certification ECU (smart key ECU assembly) judges and certifies the key ID code received from the door control receiver assembly.
(b) After the key certification OK is confirmed, the certification ECU (smart key ECU assembly) transmits an unlock stand-by signal to the touch sensor of the relevant door.
(c) If a touch sensor is touched in this condition, the certification ECU (smart key ECU assembly) transmits a door unlock request signal to the main body ECU (multiplex network body ECU), and unlocks either the driver door or all doors.
-
The front door outside handle assembly (for driver side) unlocks the driver door.*
*: except for Korea and Mexico
-
The front door outside handle assembly (for front passenger side) unlocks all doors.*
*: w/ Entry System Back Door Open Function and for Korea and Mexico
(d) The main body ECU (multiplex network body ECU) sounds the wireless door lock buzzer twice, and the main body ECU (multiplex network body ECU) flashes the hazard warning lights twice, as an answer back for entry unlock.
8. ENTRY LOCK FUNCTION

*: w/ Entry System Back Door Open Function
(c) The certification ECU (smart key ECU assembly) judges and certifies the ID code. It then checks the location of the key, and if all doors are closed, the ECU transmits a door lock signal to the main body ECU (multiplex network body ECU).
(d) The main body ECU (multiplex network body ECU) receives this signal and actuates the lock motors.
(e) The main body ECU (multiplex network body ECU) blinks the hazard warning lights once and the main body ECU (multiplex network body ECU) sounds the wireless door lock buzzer once as an answerback for the entry lock function.

12. BATTERY SAVING
(a) Vehicle Battery Saving Function
In the smart key system, signals are emitted outside the vehicle at a prescribed interval (0.25 seconds) when the doors are locked. Therefore, the vehicle battery could be drained if the vehicle remains parked for a long time. For this reason, the controls listed below are affected:
|
Condition |
Control |
|---|---|
|
Both conditions below are met for 5 days:
|
Signal transmission interval is extended from 0.25 to 0.75 seconds |
|
Both conditions below are met for 14 days:
|
The smart key system is automatically deactivates |
Reinstatement Conditions
- A wireless door lock control signal (lock, unlock) is input and the ID code matches.
- A user carries the key and touches a lock sensor on a door outside handle assembly.
- The driver door is locked or unlocked by the mechanical key.
(b) Key Battery and Vehicle Battery Saving Function
In the smart key system, if the key is constantly in the exterior detection area of the doors, the system maintains periodic communication with the key. Therefore, if the vehicle remains parked in that state for a long time, the key battery and vehicle battery could be drained. For this reason, if this state continues longer than 10 minutes, the smart key system automatically becomes deactivated.
Reinstatement Conditions
- A wireless door lock control signal (lock, unlock) is input and the ID code matches.
- A user carries the key and touches a lock sensor on a door outside handle assembly.
- A door is locked or unlocked by the mechanical key.
