That’s the glory of keyless entry and push-button start, combined with a garage remote… The keys are “in my bag somewhere” (if my car unlocks and starts then they’re still in there) and my garage door opener is on my visor. No fiddling with keys required!
Actually I was told that the reason they do this it that keeping a separate key ‘somewhere’ would assume that the car never would make any one way trips away from that location. They keep both keys together so that when they decide to get rid of the car (i.e. sell it) they have 2 keys to sell it with.
