Special relativity tells us that object in motion get contracted. If that's the case, I can have a T-shape key and a U-shape lock and, as the key must move to get into the lock, length contraction will make it shorter than the lock and not being able to reach the end (not opening the lock).
From the key point of view, as the lock is the one moving, it is contracted and the key can reach the end of the U-shape lock, opening the lock.
Will I open, or not, the lock?
