If your fob looks like this one or you own a 2008, 2007, 2006 Tribeca, Impreza, Legacy/Outback, 2005 Legacy or Outback this programing procedure should work for your car.
Your subaru can accept four different codes so you can use four keyless entry fob. To register a new transmitter with the keyless entry system, it is necessary to program the transmitter’s eight digit code (identification number) into the cars system.
First let us start by locating and writing down the eight digit code. Sometimes you can find this code on the back on the key fob on a white sticker above the panic button. If it is not there or has fallen off you will need to open the remote as if you were going to change the battery (CR 2025). To do this you will need to get a flat screw driver and at the top of the remote insert into the hole and twist the screw driver and that will open the remote. With the remote open you will see that white sticker with the eight digit code… Write that down on a separate piece of paper or enter it into your cell phone for later and close the remote.
Once you have your eight digit code we can begin programming. I would read these instructions completely at least once before beginning. As everything has to be done rather quickly.
First enter the car so you are sitting in the driver seat. *Note all doors, rear gate or trunk lid all need to be closed. Wait for the dome light to go out.
Next open and close the driver’s door.
Next put the key into the ignition and the turn the key from LOCK to the ON position ten times. (Within 15 seconds)
Next open the driver’s door and then close it.
If done properly you will hear an electronic tone sound once, a buzzer will continue to sound and the interior light will flash until the transmitter codes are completely registered.
If you do not perform the steps above within 45 seconds an error will occur and you will not hear the tone or buzzer and the dome light won’t flash. If this happened you will need to start over again.
While the buzzer is going you will need to enter your eight digit code using the driver’s side door lock button. You will do this by pushing the button towards LOCK the same number as the first number of your code. When you’re done entering that number pull it towards UNLOCK ONCE. You will need to do this to enter the rest of the seven numbers.
For Example: If your code is 3 2 7 xxxxx. You would push it towards LOCK three times then pull to UNLOCK once then push towards LOCK two times then pull towards UNLOCK once then push towards LOCK seven times then UNLOCK once and so on.
Once you have entered all eight digits you will hear another sound at this point you will need to reenter the code in the same manner starting with the first number in full series.
Once you have entered the eight digits the second time if the two codes matched up you will hear a beep and the doors should LOCK and then UNLOCK.
Next press lock and then unlock on the key fob. Then turn OFF the key and remove it. WAIT 2-3 seconds and you will hear a click. Next open and then close the driver’s door. WAIT 5 seconds and then the key fob should start working.
That’s it you have just successfully just programmed a keyless entry key fob to work with your Subaru Legacy.
*Note: Make sure no one else is operating their keyless entry system within range of your vehicle while you are programming your transmitters. It is possible that their transmitter code will be programmed into your system which will allow them unauthorized access to your vehicle.
*Also Note: That you can locate this procedure in your owner’s manual on page 2-18. Your dealer can also program your remote for a fee. They have a computer that will program it to your car rather than going though this procedure.
