A: Go to next step 

1. Move the key as described below and perform the operation inspection.

   HINT: 

   • When the key is brought near the door outside handle assembly or outside electrical key oscillator, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
   • The transmitting waves of the wireless functions and entry functions are the same, but the wave logic is different. Therefore, it is possible that only the wireless functions or only the entry functions are affected by wave interference.
2. Bring the key near the driver door outside handle assembly, and perform a front driver door entry lock and unlock operation check.

   HINT: 

   When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

3. Bring the key near the front passenger door outside handle assembly, and perform a front passenger door entry lock and unlock operation check.*

   HINT: 

   When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the door outside handle assembly, communication is not possible.

4. Bring the key near the outside electrical key oscillator (for rear side), and perform an entry back door open function check.*

   HINT: 

   When pressing the lock switch, hold the electrical key transmitter about 1 m (3.28 ft.) above the ground and about 0.3 m (0.984 ft.) away from the vehicle as shown in the illustration.

   NOTE:

   If the key is brought within 0.2 m (0.656 ft.) of the rear bumper, communication is not possible.

   HINT: 

   If the inspection result indicates that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
