Resolved problem:

1. Door and trunk locks are electromechanical. They do need electricity to work.
2. Battery pack on hot and cold wires under hood gave enough electricity allow keys to work.
3. Dealer told me I might have to use a screw driver to open hood latch thru grill. Then I could open hood to get to hot and cold terminals.

Thanks for your suggestions.
