All my life, I’ve been afraid of locking my keys in my car. For many years I carried a duplicate car key in my wallet. That isn’t practical anymore because car keys aren’t just plain old flat keys anymore; they all have that huge fat plastic thing on them.
I did lock keys into a car many years ago, and it didn’t go well. It was a friend’s car that I had borrowed, and the helpful police officer who got it unlocked damaged the locking mechanism. A few years ago I almost locked my keys into a rental car, but the car had a feature that prevented the doors from locking if the keys were in the ignition. My present car doesn’t have this.
I bought one of those little magnetic key-hiding boxes; it fell off. So I went to a locksmith’s shop and bought one with a much more powerful magnet. It fell off.
Are there any practical strategies for avoiding this problem, other than “don’t lock your keys in your car” or “don’t lock your car at all”?
