Hey.. im in the process of installing a viper 791xv alarm system in my truck, last night, the siren worked fine... it would beep when it was sposed to, and all that.... today, i hit lock, no chirp.. i hit unlock, no double chirp.. i arm the car and kick the tire, i see the little sensor turn red for more than .8 seconds but no beep.... no siren... i hold the lock button down and activate panic mode... and wow! siren goes off.... but.... why doesnt it work with anything else?!?!
nevermind, thanks for not helping though.. haha... i found out how! for all u people that need help with this.... open your door, make sure the dome light is on, turn ignition on, then off, then press valey button.. and bam! problems all solved :D
