HELLO?? Forget geeks getting into your gun. Just do as I would do--pull the friggin chip OUT of the gun, find the leads that go to the solenoid or other electrically actuated lock and put a battery across the wires. KISS.
If you can make it function without a battery by ripping the switch out, THEN PULL THAT OUT. That's what every 12 year old playing with Daddy's gun because he doesn't need to take responsibility for locking it up properly is going to do.
SHEEEESH!
Better yet, do the above in front of the 'smart gun' proponents at a news conference.
