A few years ago my friends and I broke the latch free while trying to break back into my running car. Locked the keys in it while starting it up at 1:30 AM out in the mountains at a wedding. I was DD and totally sober. We eventually got into the front door which was a big group effort. But the rear door latch has been noodling around ever since.
Managed to fix it today by swapping the broken (unfixable) plastic bushing onto the other side of the mechanism, and the good one into its place. Just gotta wiggle the door card back on and attach the bits.
