I have a 2001 toyo.4runner ltd. the security system goes off for no reason. I do not have the remote keyless entry keyfob , don't think that has anything to do with it. I've looked for a fuse to disable it but there isn't one. I have had this truck for 7days , it has woke me up in the middle of the night 4 of the 7 days. I talked to a friend at the dealership and of course they would need to look at it , but I'm one of those people that will try everything I can first before I do that. Please help I'm tired.
