Can I lock a key inside by using another key?

I have a Sienna 2020 XLE. I misplaced my key while giving somebody else a jump. It might be somewhere in the van or under the hood. I was able to drive and then lock up using the spare key. Is it possible to lock the van with one key while there's another key still inside?

If all the doors are closed, the van will let you lock a fob inside with the other key. It won’t though if you try with the switch on the door with the door open. If the van starts with the spare key outside, the lost key is definitely in the van.
