Hello,

Is there a customer programming method for the 05 Impreza remotes?

This is right out of the owner's manual..... Kinda like the hokey-pokey

Disarm the system
open driver's door
sit in driver's seat
Close door
lock to on 10 times ending in lock position
horn will sound to indicate programming mode
open driver's door
close driver's door
press and release any button on remote
horn will sound twice
Remove key from ignition to complete programming
