Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer, my name is ***** ***** to help. I cannot see or hear your vehicle so I realy on your patience and input to my questions so I can better help you, I read your notes and have a question before we proceed. I s this the original battery in this vehicle?
Then the first thing I would do is a proper load test on the battery because if it gets low it will trigger the alarm.
Yup that can happen when batteries get low in electronic devices they go haywire. Didn't know you had a garage door opener . But like I said if that battery is original I would replace it soon or you will have the same issue. I don't know if you knew that garages with openers used to open themselves when planes flew over them , radio frequencies effected them. Any way glad you found it good luck.
