Keyless Entry Receiver: Service and Repair
Resynchronization
Resynchronization may be necessary due to the security method used by the Remote Control Door Lock Receiver system. The transmitter does not send
the same signal twice to the receiver. The receiver will not respond to a signal it has sent previously. This prevents anyone from recording and playing
back the signal from the transmitter.
Resynchronization does not send the mathematical formula to the receiver, it simply verifies the previously programmed mathematical formula in the
transmitter. Resynchronization only works if the transmitter is already programmed.
Resynchronization may be necessary if:
^
The transmitter battery is very weak.
^
The transmitter battery is changed.
^
The vehicle battery is very weak.
^
The vehicle battery is changed.
^
The vehicle battery is disconnected.
^
The transmitter is pressed greater than 255 times outside the range of the receiver.
To Resynchronize the transmitter with the receiver:
1. Depress the Lock and Unlock buttons on the transmitter simultaneously for 7 seconds.
2. The receiver will acknowledge resynchronization by:
A. If all doors are locked, the receiver will unlock and lock all doors except the driver's door.
B. If all doors are unlocked, the receiver will lock all doors.
