2003 4 Runner - How Do I Reprogram Rear Window?

On the 2003 4 Runner, using the key to close the rear window also locks all the doors. Does anyone know how I reprogram this so I can close the window without locking the doors? The manual says the dealer can do it, but I would like to know how myself. Thanks.

Ask them how. If they are any good then they will tell you the procedure. They don't use this procedure anyway, they just use computers.
