My car alarm is going off randomly here in MS. Humid and hot right now ...maybe related? I have looked at the hood latch sensor, the 4 door sensors, and the rear hatch sensor. All seem to be working well. No water intrusion. The hood latch cable broke when reinstalling so I will replace with new latch/cable. The YotaMD key fob no longer remote operates the alarm but the red light illuminates on the FOB. I have to right turn the key twice to manually lock the truck. The security light blinks normal every 3 seconds, but the alarm has a mind of its own. It usually goes off in the early morning hours. 2003 Lexus LX-470. Any advice?
