May have been posted already so please point me in right direction .on a ferry crossing how do you guys and gals stop your alarm going off . I left mine unlocked but it seams to lock it's self when stationery for a while with no keys in ignition so my alarm is constantly go off . I have a shuttle base camper so has a cat 1 alarm . Is it just going to keep happening lol . I tried the double lock on the button but that seams to just disable the internal alarm censor .hink its called dead lock .thanks for your time
