Cool! Does the Prius system detect the remote fob or do you have to press a button on the fob?

If someone stole or found your keys it would be easy for them to detect which vehicle in a parking lot was yours by pressing the key fob auto-start, lock/unlock (lights flash), or even distress horn button.

I never thought of this before because I do not carry a remote vehicle starter, I have too much stuff on my keyrings now.

Once in your vehicle a thief could also then usually determine your home address from the ownership/insurance papers and access your house with the keys on the keyring or with the garage door opener in the vehicle.
