When we lock our CRV, the alarm goes off. There are many times when we come out of a store only to hear the horn blasting. Also of note, sometimes the horn honks if we lock it and other times it does not. Read somewhere that there can be a sensor issue. We have an appointment next week at the dealer but are not too keen on taking it there and coming away with a huge bill. Hoping someone can provide assistance so we can DIY. Thanks in advance!
