To be honest the smart entry is a serious blessing. My first experience was on CL9 had the smart card and knob for ignition. Even my Passo had it, remote and The Prius well obviously. Though I didn't like the one on 2nd Gen Prius where the remote had to be inserted in a slot. 3rd Gen Prius system is stupid sometimes as well if you ask me. Everytime the car is being washed it keeps locking and unlocking itself depending upon where water is landing. There's a stupid habit you have of pulling the handle to check if the car is locked and if it was locked it then gets unlocked when checking under this built in habit. The one on passo had a button like on Landcruiser and CL9 had a sensor.
But the convenience of not taking out a remote or key from the pocket is a convenience and a bad habit to make you lazy when getting into a standard car.
