I was awoke to the sound of my truck's horn (alarm) going off. Sounded like when you hit the panic button on the key fob. I jumped from my bed grabbed my gun and went outside to investigate. I thought someone was trying to steal my truck. I live on an acre of land with minimal neighbors around me, I say that to say upon seeing my truck and surroundings that no one was there. The horn was blasting and my lights was all flashing, but no one was around. Upon closer inspection the truck was locked, no glass broke, nothing. I went back inside and started hitting my panic button on my key fob to shut it up. The horn finally stopped blasting.
