Condition
Some customers may comment on an inoperative remote keyless entry transmitter.
Cause
While there are multiple reasons possible for the remote keyless entry system to be inoperative, review of warranty returns indicate this condition may be caused by a simple dead battery in the transmitter.
Correction
When attempting to diagnose an inoperative keyless entry transmitter, you should verify the following:
- Press any button on the remote and verify that the red LED (1) on the remote lights up. If the LED fails to illuminate, replace the battery. Refer to Remote Transmitter Battery Replacement in this bulletin.
- If the LED does illuminate, refer to Keyless Entry System Malfunction in SI.
Remote Transmitter Battery Replacement
1. Remove the crosshead screw (1) from the back of the transmitter.
2. Pop the two halves of the case apart and remove the module (1).
3. Using a coin, turn the battery compartment door 1/8 of a turn, aligning the arrow with the word "open."
Important
Be careful not to lose the rubber gasket (2) as it acts as a water and dirt seal to protect the module.
4. The battery compartment door/holder (1) has three retaining tabs that capture and hold the battery. There is also a very thin rubber gasket (2) on the lip of the door.
5. Remove the battery (3) and discard in the appropriate recycling container.
Important
The battery compartment door/holder is not marked for polarity. If the battery is installed incorrectly, the transmitter will not function.
6. Install a replacement lithium battery (type CR 1620), to the battery compartment cover/holder (1) so that the three plastic fingers retain it. The battery should be installed with the positive or + side inward toward the lid of the battery holder. When properly installed to the holder you should not be able to see the positive side of the battery.
Important
Use care not to pinch or roll the rubber gasket when locking the battery door.
7. Install the battery door/holder to the module and lock by turning 1/8 turn.
8. Install the module to the transmitter. It is only possible to orient it in one direction.
9. Snap the two halves of the transmitter body back together. Be sure to engage the locking tab first, then squeeze together.
10. Install the crosshead screw.
