T-20 Driver
Pick Tool
Panel Removal Tool
Digital Multimter/Voltmeter
10KΩ Resistor
Description
In order to activate KeylessGo vehicle entry during remote start, an extra harness will have to be run to a separate
CAN connector in the vehicle. The aforementioned harness will be plugged into the 2 pin port next to the main
connector on the Smartkey Starter® module. These instructions assume the Smartkey Starter® has already been
installed in the vehicle and is working properly.
Instructions
1. Locate the CAN distribution block that houses the KeylessGo connector. (see location chart below)
2. Remove all connectors from the block that contain brown and brown/red twisted wires.
3. Locate the KeylessGo module (see location chart below)
4. Unplug the KeylessGo module.
5. Unclip and remove the connector cover from the KeylessGo connector.
6. Locate the twisted brown and brown/red wires in the plug.
7. Insert a 10kΩ resistor between the brown and brown/red wires in the connector.
8. Using your meter, measure the resistance between the two wires on each plug at the CAN block that were removed
in step 2 until you find the plug that reads 10kΩ across the two wires.
9. Plug all the other connectors back into the CAN block except for the KeylessGo connector that you located in step 8
10.Using a pick tool or small flat blade, open the retaining clip that holds the connecting terminals on the side of the
connector housing.
11.Using a pick tool or small flat blade release the tabs on each pin and remove them from the connector housing.
There are 2 separate times the release tab will need to be pressed down to remove it from the connector housing.
12.Close the retaining clip and put the empty connector housing back into the CAN block.
13.Insert the pins into the provided plug housing making sure the polarity is correct with the extension harness coming
from the Smartkey Starter®. Brown/red--->Brown/red and Brown--->Brown
14.Close the retaining clip on the new connector.
15.Plug the connector in to the harness from the Smartkey Starter®.
