With the one that works i tried to reprogram it but nothing happens, the guy i got it off saod he dropped it and it stopped working but dont believe him.for some reason cos they both dont work, so how would i know if theyre the right remotes or how to get them working again without spending.a tonn of momey? Thanks in advance
