As I stated in a previous post, both keyless entry and / or the usual wireless-based finger-operated lock-unlock function in the Prius-C, at least, can be switched off by a dealer if the owner wishes.

The latter, in particular, has been around for a long time and should be really easy to forge by recording the signals when owners get into their cars.

I'm quite critical of a lot of techie gadgets, which do little of real value and only complicate things.  And we have to remember every increase in complexity entails an increase in vulnerability.  (I heard of a situation this afternoon where a family with an ultra-modern house which only had electrically-operated doors found they had to climb in & out of the windows because grid power had failed during the recent weather :-).

SO call me soft, but now I have one I'm not about to disable it!  When you're trying to get into the car in pouring rain without an unbrella, or carrying stuff and can't fish around for the keys, there's nothing like it.
