The overhead switch is probably turned off.
If the key has the built in remote buttons, it has sentry key.
If you take off the back of the wii remote, you should see a red button. on the wii console, if you open the cover to the left of where you insert the disk on the front. press both of these buttons at the same time(holding the buttons for a few sec.), and if the wii remote has batteries, it should sync the remote to the console.
Press the power button on the console, or if you have a Wii Remote connected to the console, the power button on the remote. The power button on the console is located to the top-left of the disk slot, and above the D-Pad on the remote.
Pull up the flap on the console and press sync (the red button). If that doesn't work, take the back off the remote where the batteries are and press the sync button there at the same time as the console button.
First you need to sync it with the wii console. Open the panel on the wii console and you'll find a sync button there, and open the battery door on the remote and you'll see a sync button there as well. Click on both of them together and that will sync the remote with your console. You will only need to this once. Then in each game you play you have a way to add a remote (by clicking on buttons 1 and 2 together).
There's a red button inside the remote's battery compartment and another one in the SD card slot on the console (right above the eject button and below the reset button). Push the 2 red buttons simultaneously and they will sync
well, pressing any of the buttons should at least do something. if there are no lights at the bottom of the remote, then change the batteries and try again. If the light is flashing but that's it, then you should sync the remote to the console.
On the wii remote sync screen press 1and 2 simultaneously to use it as a guest remote. If you'd rather it was synced to the wii instead of the WiiU, you can resync it using the sync buttons. You can always resync a remote to either console if you want.
behind the ignition switch they go bad often
Remote controlled gates are powered by buttons that send signals to receivers located on the gates. Once the signals are received the gates open.
There are 4 buttons on the overhead console that operate the power doors(the 2 sliding doors and the rear hatch and a power button) The 1st button on the left is marked on/off. This button powers the buttons by each of the sliding doors.
The RKE harness (remote keyless entry) is located under the center console. My guess is your looking to program a remote. The wires you jumper to do so are A and G. These are purple and black. -jeff
