    I've had this Prius for almost 3 years and I've never noticed this button. It resides just to the right of the hood release. Any ideas?

    Judging from it’s out-of-the-way position, I would venture a guess that its part of an after market alarm system.? To say the least, from an after market accessory of some sort. Most certainly it is not a stock configuration.

    Yeah, I agree it looks aftermarket. There is no alarm on the car that I know of.

    Thanks

    Agreed. Unfortunately, they violated the #1 rule in after-market installation which is: "drill no holes; a good install can be returned to 100% OEM." Considering the number of unused blanks on the dash, it's surprising.

    Some dealers put the KARR system on early gen 3's to protect theft off the lot. It has a few more bells and whistles than the OEM alarm: Motion detection with "warn away", shatter sensors for glass breakage, rolling codes and valet mode. Here's a writeup on how it works: (If it ain't broke, don't fix it!)
    Re-programming KARR alarm
    Make sure Karr is disarmed (no LED lights)
    Turn Prius on
    Press and release Karr button 3 times
    Short LED light with 1 short horn
    Before 3 seconds, turn Prius off
    Horn will give a short-long chirp
    Within 3 seconds, turn Prius back on (now in programming mode)
    Horn will give a long-short chirp
    Press Karr button one time per option (there are 4 options) the Karr LED will flash the number of times per option you are on.

    Option 1 (one flash): wait ½ second and horn should chirp once (auto-lock with ignition on)
    Option 2 (two flashes): wait ½ second and horn should chirp once (auto unlock with ignition off)
    Option 3 (three flashes): wait ½ second and horn should chirp twice (passive arming and lock without lock)
    Option 4 (four flashes): wait ½ second and horn should chirp twice (active arming)

    Turn Prius off to exit programming.
    Get out and arm…LED should flash.
    Wait a bit and then attempt to disarm with fob.
    Valet mode – car on, press and hold for 5 seconds until solid blue LED
    Valet mode off – within 3 seconds of Prius on, press and hold until LED off
