As a contrast, my last two Hertz rentals (Chevy Cruze and Mazda 6) had one keyless unit with switchblade key and the corporate fob. That's it! Very welcome with the warmer weather and no jacket pocket into which to stick a huge mass of keys.
I have an Avis rental in YVR (Vancouver BC) right now which is a Hyundai (sp?) Accent with only one button-less key and no fob.
