Battery Replacement

Warning

Never allow children to play with the RKE transmitter. The transmitter contains a small battery, which can be a choking hazard. If swallowed, internal burns can occur, resulting in severe injury or death. Seek medical attention immediately if a battery is swallowed.

Warning

To avoid personal injury, do not touch metal surfaces on the RKE transmitter when it has been exposed to extreme heat. These surfaces can be hot to the touch at temperatures above 59 °C (138 °F).

Caution

When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.

Always replace the battery with the correct type. Replacing the battery with an incorrect type could potentially create a risk of battery explosion. Dispose of used batteries according to instructions and local laws. Do not attempt to burn, crush, or cut the used battery, and avoid exposing the battery to environments with extremely low air pressures or high temperatures.

Caution

If the RKE transmitter is not reassembled properly, liquids could enter the housing and damage the circuitry, resulting in an RKE transmitter malfunction and/or failure. To prevent damage, always follow the steps for RKE transmitter reassembly in this manual to ensure the transmitter is sealed properly whenever the RKE transmitter is opened.

Replace the battery in the transmitter soon if the DIC displays REPLACE BATTERY IN REMOTE KEY. To replace the battery:

1. Press the button on the side of the RKE transmitter near the bottom and pull the key out. Never pull the key out without pressing the button.

2. Insert a flat, thin object in the center of the transmitter to separate and remove the back cover.

3. Lift the battery with a non-metal flat object.

4. Remove the battery. 5. Insert the new battery, positive side

toward the back cover. Replace with a CR2032 or equivalent battery.

6. Ensure that the silicone mat is correctly positioned with no gaps or wrinkles.

7. Set transmitter button side down on a hard surface and press the other half straight down to force the halves together.

8. Reinsert the key.

If equipped, this feature allows the engine to be started from outside of the vehicle. / : This button will be on the RKE transmitter if the vehicle has remote start. The climate control system will use the previous settings during a remote start. The rear defog may come on during a remote start based on cold ambient conditions. The rear fog indicator light does not come on during a remote start. If the vehicle has heated or ventilated seats, they may come on during a remote start. See Heated and Ventilated Front Seats 0 42. If equipped with a remote start heated steering wheel, the heated wheel will turn on automatically in remote start along with the heated seats when it is cold outside. See Heated Steering Wheel 0 91. Laws in some local communities may restrict the use of remote starters. For example, some laws may require a person using remote start to have the vehicle in view. Check local regulations for any requirements. Do not use remote start if the vehicle is low on fuel as it may run out of fuel.

Other conditions can affect the performance of the transmitter. See Remote Keyless Entry (RKE) System 0 7.
