I have diff places I keep keys. I have LOTS of vehicles lol. 3 trucks, a E250 van, car and all the tractors, quads etc. turns out to be a lot of keys to lose.
My main key ring I carry all the time, it has a clip that I clip to a belt loop, off that clip is 4 links of chain so I can tuck them in my pocket so I don’t jungle.
Car keys aren’t on my main ring, those get dropped in a drawer in the kitchen or on my night stand, NEVER anywhere else. If I’m out and about with multiple sets of car keys I put them on the clip of the main set and drop those in a cup holder or center console of the vehicle I’m driving so the keys don’t become too much.
While I’m in the shop I hate things in my pockets crawling around on the ground etc. in my shop I have cabinets, the first drawer, I dump the contents of my pockets in to, shut the drawer and get to work. That drawer is the ONLY place keys, wallet, phone etc goes. Spent too much time hunting for stuff in the shop after dumping my pockets because keys or a wallet sucks to lay on.
RFID chips concern me, I prob won’t volunteer to support that technology, won’t spend money on them. RFID’s work in the Book of revelations.
