Keys are something I can't seem to do without. In my left front pocket is a one key ring with eleven keys:
lock for tonneau cover
4 keys ? ( afraid to throw away)
Right front pocket I have two sets, one with 8 keys :
motorhome drivers door
motorhome house door deadbolt
motorhome house door
motorhome large storage doors
motorhome small storage doors
2 keys ?
one with 13 keys:
these are keys I use at work
Also in my briefcase I have another set with about 7 or 8 keys I also use at work.
Wouldn't be nice to return to the days when the keys were left in the car and who needed a lock on anything else.
