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?

This happened happened to my Toyota (1KDFTV Hilux) a couple of years ago. After months of troubleshooting, it was the battery that was causing it. Replaced the battery and it never alarmed again. Hope this is just the case of your LC.
