my vehicle alarm was going off not sure why. I took the key out to open the vehicle from the key fob. I tried first to shut it off (by the alarm button) but it only blink .And the alarm kept going on got into the vehicle, two signal lights came on now (blinking) .Both the alarm and signal lights going off. my key is still in my hands . Everything finally shutting off once I put the key in and put it in drive as I had my foot on the brake any ideas? thank you

My car did that for a few nights straight. Had to replace the car battery.
