Keyless Entry Transmitter

The transmitter is a hand-held device that has three buttons which command the functions of the system. i.e transmitter sends a radio signal to the receiver, which helps carry out the functions of the keyless entry system.

The range of the transmitter is about 1m to 10 m (3.2 feet to 33 feet). At times a decrease in range may be noticed. This is normal for any remote lock control system. If the transmitter does not work or if you have to stand closer to the vehicle for the transmitter to work, perform the following:
^ Check to determine if battery replacement is necessary.
^ Check the distance. You may be too far from the vehicle. You may need to stand closer during rainy or showy weather.
^ Check the location. Other vehicles or objects may be blocking the signal. Take a few steps to the left or right
