    I would break out a beer, let her talk about all her problems, constantly nod your head in agreement, and that should help her sensitivity out. good luck brother.

    Yo, resurrecting this. 2017 Off-Road with the (ugh) Karr system installed at the dealership.

    I need to lower sensitivity. I stuck my head under the steering wheel but couldn't find the brain with the dial on it. Is it hidden behind a trim panel in these trucks? Thanks.

    Gonna answer my own question here, in case it helps anyone. I had to call Karr to get assistance. Dude on the phone was great.

    The Karr alarm on these trucks is a bit different from what I found online for previous gens. There's no longer a big black box with a dial on it. What you have instead is the little LED light unit with the valet button underneath.

    To adjust sensitivity do the following:
    1. Key on/off
    2. Hold the valet button for ~5 seconds. I got a honk at this point. This means programming mode is on.
    3. Press the button the # of times you want the sensitivity, from 1 (lowest) to 10 (highest)
    4. Test it by banging on the steering wheel. Full honks means full alarm. I was getting this on the default setting of 5. Quick succession of beeps means "warning" only (lower sensitivity)
    5. Key on/off to exit programming mode
    There it is. I was able to lower the sensor from 5/10 to 2/10, should do the trick.

    Mostly patches. AC Dog Platform. Tool Box.
    Try and set it off. If it doesn't go off, you probably don't have one. Check owner's manual.

    Looks like the above method works on 19’s. Didn’t have to bang on the steering wheel to test, it just slightly honked after pressing the button to adjust the sensitivity.
