I'm paranoid about keys after DH locked his keys in the car & my keys were in the house. Guess where house keys were, yes in the car (same key ring). Phone call to try & find his S, no luck. Sat on front wall, luckily a lovely warm summer evening, a neighbour went to get a bunch of keys, still no luck.
Eventually DH had a bright idea, if he climbed over garden wall he could hook the garage keys off the coffee table by the french windows, hand through cat flat & a garden cane
. Keys for garage retrieved DH went for his fishing net as he could reach bottom bolts but not top ones. Guess what it worked
I never again went out without my handbag & door keys.
When I go away I always take my spare car keys, if I lock my car & open the boot separately, the boot locks automatically when you close it. I'm paranoid now
. Two of my neighbours have spare keys for my house as they feed the cat when I'm away.
