  1. Jeff, it sounds like your 2007 Toyota Sequoia alarm shock sensor is too sensitive. You need to lower the shocks sensor sensitivity to prevent you alarm from going off when cars drive by. Some alarm systems have external shock sensors which can be adjusted externally. Some alarm systems have built in shock sensors which can only be adjusted via alarm programming. If you have never adjusted or programmed your alarm system before, our advice is that you take your car to an experienced alarm installer. It should not take more than 30 minutes from start to finish to adjust it. Hope this helps. Good luck with your 2007 Toyota Sequoia shock sensor adjustment.

  2. Why does the 2007 Toyota Sequoia alarm keep going off suddenly even without triggering or tampering the car? Battery still good. Thanks
