Run a new cable & install another door controller, or don't worry about it.

You could experiment with some foil glued to the back of each reader. RF can do strange things, so you'd need to test it. Have used it to stop RF interference before.

Are you sure its not that the buzzer wire is connected for feedback on both readers, so when access is granted/denied it is beeping both readers, being in parallel?
