Tips

1. Each of our products has detailed product description, please check carefully whether the information is consistent with the key you want to buy when purchasing.

2. The smart key and car remote are in complete working condition.

3. The carrier of the radio signal from the car key to the car is binary modulated by Amplitude Shift Keying (ASK) or Frequency Shift Keying (FSK), where the amplitude of the carrier varies between two levels, and frequency shift keying (FSK) Then the frequency of the carrier jumps between two different values.

4. If equipped, the ignition is on or in ACC/ACCESSORY and the power door lock switch is pressed with the driver door open, all the doors will lock and only the driver door will unlock. If the vehicle is off and locking is requested while a door is open, when all doors are closed the vehicle will check to the Keyless Access function (if equipped). If an RKE transmitter is detected and the number of RKE transmitters inside has not reduced, the driver door will unlock and the horn will chirp three times.
