Broken key from hot ignition??

If you examine the panel where the number plate light is mounted there should be a hidden key hole slot. It will be probably have seized up as it isn't normally used regularly. You might have to spray it a few times with a light releasing oil to free it up and gradually work it loose with the spare key. Don't rush this as you could snap the key or damage the lock barrel. This should give you access to the trunk without having to 'hot-wire' any of the electrics. The fault in the wiring is probably where the wires join the trunk lid from the body of the car so "Hot-wiring" probably wouldn't work.
