One day I'm doing work under my '07 Grand Cherokee, it has remote start. I have the keys in my pocket, and roll a certain way that the remote start button gets pushed not once but twice, it takes 2 pushes to engage the remote start. I heard the beep, jumped up and cancelled it! If not the engine would have started. Now I had not drained the oil but, can you imagine if I had? So if you have remote start on your vehicle as many do, take the remote OUT of your pocket when working on the vehicle. Imagine if this happened after you drained the oil and were changing the oil filter! It doesn't seem likely but it CAN happen!
