Then there is something wrong with your door. The service manual (page 8N-43) shows that the key is directly connected to the door lock. This makes sense since there has to be a way to manually unlock the door in case the central locking pump/security system module fails.

I'm not entirely sure what to tell you, but I would recommend against trying to feed voltage into one on the external bulbs in hops of powering the car since you stand the chance of damaging the voltage regulator or switching electronics.

Your best bet (IMHO) would be to jack the car up, pull the lower splash shield, and try and manually release the hood latch from underneath.

Good luck and let us know how it turns out.
