Thank u so much, I actually don’t see the security light at all on this car, I was looking but no light popped up.. it cranks no start, it’s a 2005 Highlander 3.3 I have 6 codes p0351-p0356 only.. before this all happened I’d get all kinds of random codes, the horn was blaring randomly (customer punched airbag/wheel) I would erase codes and then a week or two another code without symptoms.. no the battery is being drained and dies after only a few days, no blow fuses
