The smart key was in the diaper bag inside the car, as was my baby, and I could not get into the car. I had to call my wife and have her bring the second smart key to unlock the door. …”
NHTSA complaint #10374857, filed 2011-01, 75,500 miles“In the 2004 Toyota Prius there is a button on both back seats by the headrests that unlatches the seatback.
