Our alarm was going off at random times so we unplugged the hood latch sensor. We noticed that when we turned the car off the lights would blink as if the alarm was on. The other night we where out and noticed the remote wasn't working and we couldn't lock the doors so we manually locked them. Now we are locked out of our van, the remote doesn't work and the only key we have only fits the ignition, not the doors. Are there any alternatives besides breaking a window to get in?
