Programming Transmitters to the Vehicle Only RKE transmitters programmed to the vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer/retailer. When the replacement transmitter is programmed to the vehicle, all remaining transmitters must also be programmed. Any lost or stolen transmitters no longer work once the new transmitter is programmed. Each vehicle can have up to five transmitters programmed to it. To replace the battery: 1. Remove the screw from the back of the cover and open the cover of the transmitter. 2. Pull the transmitter out of the cover and carefully turn the circle cover of the transmitter unit toward open. 3. Remove the battery. 4. Insert the new battery, positive side facing up. Use one three-volt, CR1620, or equivalent, type battery. 5. Turn the circle cover of the transmitter unit toward close and put the transmitter unit in the cover. 6. Put the two halves back together and replace the screw. Make sure the cover is on tightly, so water will not get in. 7. Test the transmitter operation. Battery Replacement Replace the battery if the LED on the transmitter does not flash when you press the buttons. Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter. 2-5
