### Resynchronization

Resynchronization may be necessary due to the security method used by the remote function actuation system. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that the receiver has sent previously. This prevents recording and playing back the signal from the transmitter.

Resynchronization does not send the mathematical formula to the receiver. Resynchronization verifies the programmed mathematical formula that is in the transmitter. Resynchronization is successful only if the transmitter is already programmed.

Resynchronization may be necessary under the following conditions:

• | The transmitter is weak.

• | The transmitter battery was changed.

• | The vehicle battery is very weak.

• | The vehicle battery was changed.

• | The vehicle battery was disconnected.

• | The transmitter is pressed more than 255 times outside of the range of the receiver.

Complete the following steps in order to resynchronize the transmitter with the receiver:

1. Press the LOCK and the UNLOCK buttons on the transmitter simultaneously for 7 seconds.
2. The receiver will acknowledge resynchronization in the following manner:

• | If all of the doors are locked, the receiver will unlock and lock all of the doors except the driver door.

• | If all of the doors are unlocked, the receiver will lock all of the doors.
