Can this possibly work?

Older Nissan's had an unlock sensor if you crashed. Flat hit on the centre of the roof with open palm and the doors all popped open.

I did break into a vehicle once, and the owner thanked me. It was on fire and I put out the fire, all he had to replace was a driver's window that I took out with extreme violence with a CO2 fire extinguisher, before opening the engine bay  and cooling off the red hot battery cable that was shorted to the fuel line. Then disconnected the battery, luckily the terminal was loose so I did not have to do the fire dept method and knock the terminal off with the fire extinguisher as well.

Was not so lucky with a Mk1 Ford Escort though. Took 30 seconds from the shout from the driver to the car being completely engulfed.  Called the fire dept and they got there in 3 minutes, but all they could do was put out the remains, pull it to the side and put sand in the hole in the tar.
