I have a 2004 Toyota Corolla S, 1.8L, and it has 70,000 miles. For last few months we have noticed that sometimes the alarm is hard to turn off when we push the remote button. We have to push it over and over and it will eventually turn off. THen today I just noticed that it isn't arming at all. The remote still locks and unlocks the doors but the alarm will not activate. Any ideas?
