Once upon a time there were cars that came with two different keys, one for the car and the other for the door which allowed you to do that dance with one set of keys. Either take one off the key ring while doing it, or I had a key ring that was actually 2 rings with a quick-connect between them.If you work in an office with outdoor parking, say, and you're not planning on using your car during the day, you need to go down to the parking lot midday, start your car with one set of keys, lock the car, and go back to your office. After your car has been running a while and warmed up sufficiently, go back down and unlock the car with the second set of keys, shut the car off and remove the first set of keys from the ignition. If you don't do this, your car may not start in the evening when you leave work. Didn't need to do this everyday in winter, only on very cold days. But keeping the second set of keys with you just becomes a habit.
For example, at one point GMs one of the two keys had a round key head and the other a square, to help you tell them apart. The square matched with the gap between the wings on the ignition mechanism, the round one was for the door and trunk locks.
It's been a few decades since any manufacturer has keyed separate locks like that though, AFAIK.
