No PB in the ignition, only the trunk lock to free the stuck tumblers.
Mr. Moly is good stuff, tenacious oil with MoS2. Graphite is good once, ... when the lock is being produced, but powdered graphite can build up in the recesses where the lock tumblers need to go, impacting them and causing the lock to not operate (bad thing). The liquid-based stuff will move around while you operate the lock.
Living in the rust-belt, my winter cars get lock lube treatments at least twice/year as preventative maintenance. With graphite they'd be toast before they're out of warranty.
