The Subaru Forester comes standard with a keyless entry system; however, you may need to install additional remotes to use with your car. You can do this by programming additional transmitters. Up to four transmitters can be programmed to the Forester at any given time. The process for installing a new Forester remote is quite tedious and requires concentration.

  1. 1

    Examine your keyless entry package and make a note of the serial number on the front of the package. You'll need this to install the remote. If you don't have a package, pry open the remote with a flathead screwdriver and find the number on the internal circuit board.

  2. 2

    Verify all the doors, including the rear hatch, are closed. Sit in the driver side seat. Open the driver side door, and then close it.

  3. 3

    Insert the key into the ignition. Turn it from "Off" to "On" 10 times (within 15 seconds). You'll hear an ignition chime.

  4. 4

    Open the driver side door then close it. Now you'll hear a steady chiming. Push the "Lock" button on the driver side door switch a number of times equal to the first digit in the keyless entry serial number. For example, if the serial number begins with "3," you would push "Lock" three times. Push the "Unlock" button on the driver side door switch when you are finished.

  5. 5

    Push the "Lock" button a number of times equal to the second digit, and then press "Unlock." Repeat this process for the entire serial number. The serial number is eight digits. You'll hear another steady chime.

  6. 6

    Repeat the process, starting over with the first digit of the serial number. When you are finished, turn the ignition off and remove the key.
