" These remotes don't work"

Think about that statement for a minute. Isnt it more likely that:

(1) The device you're trying to control has a bad remote sensor.
(2) You didnt follow the programming instructions correctly.
(3) You got tired of pressing the ON button 347 times to try each
code.
(4) You blew by the setting that turns on your device.
(5) You have an empty beer can, or a half-eaten Subway sandwitch, or a
smear of ketchup in front of the TV's remote control sensor.
