6 Step 4) Plug the key switch back into the remote, but leave the small green board unplugged from both the key switch and the remote.

7 Step 5) Connect the wired reprogrammer to your computer via the USB port. Note: If any of the wires in Steps 6 through 8 do not push down all the way, this is OK. They only need to make a firm connection.

8 Step 6) Connect the black wire to pin 1 on the 18R2. See pictures below.

9 Step 7) Connect the white wire to pin 4 on the 18R2. See pictures below.

10 Step 8) Connect the green wire to pin 3 on the 18R2. See pictures below.

12 Step 12) Click on the firmware for the unit you are upgrading, in this case it would be 18R spy. Click OK. Step 13) Wait for the below window to reach 100% and disappear.

13 Step 16) Hold the SYNC button on the 18R2 and power on the 18R2 at the same time you are holding this button. You should see red LEDS circle around the display. You can release the SYNC button at this time. After about 15 seconds, the 18R2 will display all green LEDs and then power off. Note: If you see all red LEDs instead of circling red LEDs when first powering on the 18R2, your USB thumb drive is not compatible with the 18R2. We suggest purchasing the Sandisk brand at Wal-mart. Purchase the cheapest one available with the lowest number of GB. Remove the USB thumb drive, and restart the 18R2. Your remote should now display when it reboots. Congratulations! You are done!
