Locate the Dongle
The dongle in your 2012 Nissan Leaf is a small, rectangular device that stores your vehicle’s keyless entry and ignition information. It is located in the center console, just beneath the climate control panel. To locate the dongle, follow these steps:
- Turn off the engine and put the car in park.
- Open the center console by pressing the button on the front of the lid.
- Locate the dongle holder, which is a small, black plastic square located just beneath the climate control panel.
- Gently push on the dongle holder to release it from its housing.
- Remove the dongle from the holder.
The dongle is a small, black plastic rectangle with a metal key ring attached to one end. The Nissan logo is printed on the front of the dongle. To view the battery status of the dongle, press one of the buttons on the side of the device. If the LED indicator light flashes red, the battery is low and needs to be replaced.
Remove the Dongle Cover
To remove the dongle cover, you’ll need to first locate it on the key fob. The dongle cover is typically a small, rectangular piece of plastic that is located on the back of the key fob. Once you have located the dongle cover, gently pry it off using your fingernail or a small flathead screwdriver. Be careful not to damage the dongle cover or the key fob itself.
Once the dongle cover is removed, you will need to remove the screw that is located inside the battery compartment. This screw typically has a Phillips head, and you can remove it using a small Phillips head screwdriver. Once the screw is removed, you can carefully lift the battery out of the battery compartment.
To replace the battery, simply insert the new battery into the battery compartment, and then replace the screw. The screw should be tightened until it is snug, but do not overtighten it. Once the screw is tightened, replace the dongle cover by snapping it back into place.
