I tried that in the parking lot at Indianapolis International Airport very early one morning. Misremembering the correct aisle made it a very long a difficult search, especially as I was exhausted...eventually, I did hear my car as I re-locked the door...When I return to the car, I often forget exactly where it is.
(Of course, Mr Van is easy to spot. Cars much less so.)
Hit the old key fob, & the parking lights flash me.
