We had a strange problem with
the Toyota this morning.
The doors opened okay, but
something froze that prevented the passenger side back door from
latching shut.
One option we considered was
to wait and see if warming the car up would fix it, but time was an
issue and I felt like this is the exact sort of problem ratchet
straps were invented for.
Probably the latch mechanism on the door that mates with the pin on the car body got stuck in open position.
Usually a spray of light oil will free them up.
