    Today I got a message on the dashboard display “Key Fob not Detected”. Couldn’t start the car with the push button. Temporary solution was to pop the button cover off, then you can put the key fob into the slot and turn it like a regular key. Thought maybe it was the fob, but a new battery didn’t help, and I tried my other fob and that didn’t work either. The message that comes up now, after starting the car with the fob and turning it off, is “Service Keyless System”.

    I found a TSB that has that error message listed, #08-047-11 …. (DTC) B25AA-01, B25A9-01, but it seems to be for a 2011, and talks about replacing both door handles with something about the proximity entry system, which my 2010 doesn’t have.

    So I have to admit, I’m stumped. Has anyone else run into this problem before?

    Howdy y'all,
    I'm getting the "Service Keyless System" message, along with intermittent "Keyfob Not Detected" messages on my 2014 SXT. Additionally, the fob still unlocks and re-locks the doors, but the lock button on the outside door handle along with the unlock sensor on the underside of the outside handle no longer work. Or rather...they weren't working, but were and are when I checked it again just a few minutes ago. The messages appear to be gone now, too. We had a torrential rainfall last week, after which I found the driver's side floorboard completely saturated, along with the above mentioned issues. I know...two separate problems, but I'm wondering if something behind the dash might have gotten wet and caused this behavior, and has since dried and returned to normal operation. Any ideas?

    I would fold down the back seats and put a dehumidifier in the trunk. Been there, done that.

    Did the seal around your door start leaking? Mine did this all of a sudden in a torrential rain. After that it just kept happening and they put some really gross black goo all under my door seal then replaced it. In summer I can wipe it off with a cloth as it gets melty. And it leaves my car window filmy in rain but Windex removes it.

    Was there another design flaw? Mine made my headliner wet and dripped from there. The goo..whatever it is, stopped it. I was very worried about water shorting something out. Lucky this was summer and the heat baked it dry the next day with windows open. I'm also all leather so that helped.
