Has this ever happened to you? You come out of a store and return to your car, but as you approach, you notice another vehicle very similar to yours? No, I didn't try to unlock the wrong car but it was an odd sensation for a moment.
Must have been thinking which side you had parked on! It's finding my car that's the problem I have as I just lock up & leave when I should check which part of the carpark it's in!
