Construction and OperationKeyThe key consists of a mechanical key, a transmitter for the wireless door lock remote control and atransceiver for the smart entry and start system, and a transponder chip for the engine immobilizer control.D The transceiver function of the key receives the signals from the oscillators and returns the ID code tothe tuner.D The transmitter function for the wireless door lock remote control has a LOCK button, UNLOCK button,TRUNK button, and PANIC button*.D The transponder chip in the key for the engine immobilizer control returns a signal to the engine switchas a response to the radio wave it received from the engine switch.D This mechanical key operates the driver door lock cylinder, glove box lock cylinder and trunk storageextension lock cylinder but cannot be used to start the engine.*: Except for Chinese modelsA total of four keys can be registered. For details, see the Camry Repair Manual.*: Except for Chinese modelsOscillator (Driver and Front Passenger Door*, Front and Rear Rooms, Trunk Inner, TrunkOuter)Each oscillator functions based on a request signal received from the certification ECU, and creates a keyactuation area that is used to detect the presence of a key.The actuation area formed by the front door oscillator and trunk outer oscillator is approximately 0.7 to 1.0 m(2.3 to 3.3 ft.) from the outside handle of the front doors, or the center of the rear bumper.D The actuation area of front door oscillator is formed by transmitting a request signal every 0.25 secondwhile the engine switch is OFF and each door is locked. In this way it detects the proximity of a key. Whenlocking the door using the lock switch on the outer door handle, the actuation area is formed when thelock switch is pressed.D The actuation area of the trunk outer oscillator is formed when the trunk open switch is ON. It is formedtwice to allow the key to be verified.D The actuation area of the front and rear room oscillator is formed when the driver door is opened orclosed, when the start button is pressed, when a warning is activated, or when the lock switch is ON.D The actuation area of the trunk inner oscillator forms when the trunk lid is closed or the trunk open switchis pressed, and is formed twice to allow the key to be verified.*: Only for G.C.C. Countries and Australian models BODY ELECTRICAL– SMART ENTRY AND START SYSTEMBE-1585.Entry Function OperationGeneralThe entry function has the following functions.Function OutlineMechanical Key(See page BE-157)The key consists of a mechanical key, a transmitter for the wireless door lock remote controland a transceiver for the smart entry and start system, and a transponder chip for the engineimmobilizer control.Wireless Door LockRemote Control(See page BE-159)This function is a convenient system for locking and unlocking all the doors or trunk, at adistance. The operation is same as wireless door lock remote control system.Entry Illumination(See page BE-39)When a key enters the actuation area of front door oscillators, the front interior light, andengine switch illumination illuminate.Entry Unlock(See page BE-160)When a key is located in the actuation area front door oscillators, the door will unlock afterthe inside of an outside door handle is touched.Entry UnlockMode Switching(See page BE-161)Allows selection of one of two modes that can be operated with the entry unlock function.DDriver Door ModeDAll Door ModeEntry Lock(See page BE-162)When a key is located in the actuation area of either front door oscillator and the powersource is OFF, the door can be locked by merely pressing the lock switch on the outside doorhandle.Trunk Open(See page BE-163)When a key is in the actuation area of the trunk outer oscillator, the trunk can be opened bymerely pressing the trunk open switch.Prevention of KeyConfinement(See page BE-164)DPrevents the confinement of the key in the vehicle by the door being locked with theoutside door handle while the key is still inside the vehicle.DIf the trunk lid is closed while the key is still in the luggage compartment, the warningbuzzer sounds. If the trunk open switch is operated the trunk lid can be opened.Warning(See page BE-166)When any of the situations below occur, the smart entry and start system causes thecertification ECU to sound the buzzer in the combination meter and the wireless door lockbuzzer, and indicate a warning on the multi-information display in order to the alert thedriver.DAn exit warning if the shift lever is in a position other than P and the power source is amode other than OFF.DAn exit warning if the shift lever is in P and the power source is a mode other than OFF.DA warning if the occupant leaves with the key in inappropriate circumstances.DA warning if the entry lock button on the door handle is operated while the key is insidethe vehicle.When any of the situations below occur, the smart entry and start system causes thecertification ECU to sound the buzzer in the combination meter and indicate a warning onthe multi-information display in order to the alert the driver.DA warning if the engine switch is operated while the key is outside the actuation area.DA warning if the key battery is weak.Battery Saving(See page BE-176)If the key remains within the actuation area of the front door oscillators, the system maintainsperiodic communication with key. Therefore, if the vehicle remains parked in that state fora long time, the key battery and the vehicle battery could be drained.Key Cancel(See page BE-177)The following key functions can be cancelled by following certain procedures.DEntry unlock/lockDTrunk openDPrevention of key confinementDWarningKey CodeRegistration(See page BE-177)A total of four keys can be registered.Enables the registering (writing and storing) of transmitter recognition codes in theEEPROM that is contained in the certification ECU. BEBODY ELECTRICAL– SMART ENTRY AND START SYSTEMBE-159Wireless Door Lock Remote Control FunctionThe wireless door lock remote control function has the following functions:FunctionOutlineAll Doors Lock Pressing the LOCK button of the transmitter (key) locks all doors.All Doors Unlock Pressing the UNLOCK button of the transmitter (key) unlocks all doors.All Doors Unlock(2-step Unlock)*1Pressing the UNLOCK button of the transmitter once unlocks the driver’s door.If the UNLOCK button is pushed again within 3 seconds, all doors unlock.Trunk Opener*2Keeping the TRUNK button of the transmitter pressed longer than about 1 secondopens the trunk lid.Answer Back*2When all doors are locked, the hazard light flashes and buzzer sounds once*3.When all doors are unlocked, the hazard light flashes and buzzer sounds twice*2,in order to indicate that the operation has been completed.Panic Alarm*3Keeping the PANIC button of the transmitter pressed longer than about 1 of asecond causes the following functions of the alarm to activate.DSounds the horn, securith horn*4 and self-power siren*5.DFlashes the hazard lights, headlights*6, and taillights*6.DIlluminates the interior light (If the interior light switch is in the DOORposition).Automatic Lock*2If none of the doors are opened within 30 seconds of being unlocked by thewireless door lock remote control, all the doors will be locked againautomatically.Door AjarWarning*1If any door is open or ajar, pressing the LOCK button of the transmitter will causethe wireless door lock buzzer to sound for about ten seconds.RepeatIf a door is not locked in response to the locking operation of the transmitter, thecertification ECU will output a lock signal after approximately 1 second.Illuminated EntryWhen all the doors are locked, pressing the UNLOCK button causes the interiorlights to illuminate simultaneously with the unlock operation.Security Sends an operation signal as a rolling code.*1:Only on models for G.C.C.
