Key Cancel Function
1. A key cancel function is provided to make it possible to disable the entry and start system. Key cancel can be operated when certain operations are performed when the vehicle is under the following conditions:
  - Engine switch (push start switch) is off.
  - Driver door is closed.
  - Driver door is unlocked.
2. The operation procedure is as follows:
  - Unlock once with the unlock button of the key.
  - Open the driver door within 5 seconds.
  - Unlock twice with the unlock button of the key within 5 seconds.
  - Repeat open → close twice for the driver door within 30 seconds, and open again. (Driver door: open → close → open → close → open)
  - Unlock twice with the unlock button of the key within 30 seconds.
  - Repeat open → close once for the driver door within 30 seconds, and open again. (Driver door: open → close → open)
  - Close the driver door within 5 seconds.
  - When key cancel is activated, the wireless door lock buzzer sounds twice.
  - To return to the original condition, perform the procedures again. When key cancel is returned, the wireless door lock buzzer sounds once.

Key Code Registration Function

The table below shows the 4 special ID code registration function modes through which up to 4 different codes can be registered. The codes are electronically registered (written and stored) in the EEPROM. For details of the recognition code registration procedure, refer to the Service Bulletin.

Mode	Function
Registration	Registers newly received codes. This mode is used whenever the certification ECU (smart key ECU assembly) is replaced.
Addition	Adds a newly received code while preserving previously registered codes. This mode is used when adding a new transmitter. If the number of codes exceeds 4, the oldest registered code is cleared first.
Confirmation	Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist.
Deletion	Clears all registered codes except one. This mode is used when keys are lost except one. The keys that are deleted cannot be re-registered.

CONSTRUCTION

Electrical Key Transmitter

The electrical key transmitter consists of a mechanical key, a transmitter for the wireless door lock control and a transceiver for the entry and start system.
The transceiver for the entry and start system receives the signals from the oscillators and returns the ID code to the door control receiver.
The transmitter for the wireless door lock control has a lock button and unlock button.
When the key battery is low, the radio wave response received from the engine switch (push start switch) is returned to the engine switch (push start switch) by the electrical key transmitter.

This mechanical key works for the driver's door, but cannot start the engine.

Door Control Receiver

The door control receiver and electrical key transmitter can operate on 2 different Radio Frequency (RF) channels. Therefore, stable signal transmission and reception will be delivered even if wave interference occurs.

When an electrical key transmitter is brought within an exterior actuation area, key verification begins. If key verification fails due to wave interference, the channel will be switched and key verification will be performed again. The multi channel system begins verification using the channel on which the last verification was successfully performed. When verification fails, the system switches to the other channel.

Step	System Operation
*a	Exterior actuation areas are created using Low Frequency (LF) waves (emitted from the vehicle at intervals of 0.25 seconds) to receive a response from the electrical key transmitter.
*b	When the electrical key transmitter is brought into an exterior actuation area, it receives LF waves from the vehicle. Using RF waves, the electrical key transmitter responds to the vehicle.
*c	Upon receiving the response from the electrical key transmitter, the certification ECU (smart key ECU assembly) activates the electrical key antennas (outside) one by one. Using LF waves, the certification ECU (smart key ECU assembly) determines which exterior actuation area the electrical key transmitter is in.
*d	The electrical key transmitter receives the LF waves from the vehicle and responds using RF waves. (The certification ECU (smart key ECU assembly) recognizes which exterior actuation area the electrical key transmitter is in.)
*e	The certification ECU (smart key ECU assembly) sends registered key ID information to the electrical key transmitter using LF waves. (Up to 4 key IDs can be registered.)
*f	The electrical key transmitter sends the key ID information using RF waves on both channels. When the certification ECU (smart key ECU assembly) receives it, verification completes.
*g	Wave interference (Channel switching)

The multi channel system changes the channels when the RF band (*b and *d) is interrupted by wave interference.

Key Operation/Warning Light

The key operation/warning light located in the combination meter helps the driver in checking the current status of the power source.

DIAGNOSIS
1. The certification ECU (smart key ECU assembly) can detect malfunctions in the start function when the power source mode is on (IG).
2. The indicator light warning continues for 15 seconds even when the power source mode is turned off.
3. The Diagnostic Trouble Code (DTC) can be read by connecting the intelligent tester to the DLC3.
4. The start function cannot be operated again if a malfunction occurs.
5. For details, refer to the Repair Manual.
