I started getting an error yesterday that my Key Fob battery is low. This is preventing me from not only summoning from the Key Fob, but also from the Phone App; and it is also preventing me from using AutoPark via double tapping Park button. I pulled both batteries out of both Key Fobs, and load tested them. They are both plenty strong. The Key Fob low battery warning also came up about 5 months ago, and lasted for a couple days, and then magically went away. I never changed the batteries, it just stopped complaining and everything went back to normal. My biggest gripe here (aside from receiving the warning when the batteries clearly aren't low) is that you are unable to use AutoPark or Summon from the Phone App when the car thinks that your Key Fob battery is low. I thought I've read on this forum that there are people who never carry their Key Fob at all. I always assumed they could still AutoPark and Summon from the Phone App. If that's true, then why the heck can't I use these features if the car thinks the Key Fob batteries are low? I even tried leaving the Key Fobs in the house, but the car still complained that the battery is low. The full message on the Phone App states, "Summon Failed. Your key fob battery level is too low."
