1936 Chevrolet sedan door/trunk locking.

I have a 1936 chevrolet sedan that currently has the original door handles and they work fine. The outdoor lock was only on the passenger side door and that key has been lost. I need to add the ability to lock my doors and not sure how to go about it. The trunk presently simply has a magnetic latch and I need to add locking to it as well? I’d be okay with keyless entry on doors as long as there is a way to get emergency entrance in the event of dead battery, or I’d be okay with keyed entry on doors and trunk.. HELP??
