A total of 7 keys can be registered.
Electrical key transmitter:
The electrical key transmitter consists of a mechanical key, a transmitter function for the wireless door lock control and a transceiver for the entry and start system.
Oscillator (each door oscillator, front, rear 1 and rear 2 indoor antenna, and back door antenna)
Each oscillator transmits the request signal received from the certification ECU (smart key ECU assembly), and forms a key detection area to detect the presence of a key. The detection area formed by each door oscillator and back door outer antenna is approximately 0.7 to 1.0 m (2.30 to 3.28 ft.) from the outside handle of each door or the center of the rear bumper.
ENTRY FUNCTION OPERATION |
The entry and start system has the following functions.
Function | Outline |
Mechanical Key | Operation is the same as a conventional mechanical key. |
Wireless Door Lock Control | This function remotely locks and unlocks all doors and the back door. Operation is the same as the wireless door lock control system. However, receiver in the certification ECU (smart key ECU assembly) uses the entry door control receiver to control locking and unlocking. |
Entry Illumination | When a person carrying the key enters the detection area, the door will enter unlock standby mode and room light will illuminate. |
Entry Unlock | When the key is located in the detection area of the door oscillator, the door will unlock by touching the inside of the outside door handle. |
