Oh, the RKE battery is for remote door lock fob, eh...? I started getting the error message that said, "RKE Battery" on the car information center last week or early this week. The error message goes away after a couple of minutes of the engine running. Now, I am getting the "RKE Battery Low" message also.
I had no idea what the error message was all about. Could find nothing about it in my owner's manual. Called my dealer's service dept. about it but they did not return my Saturday call. Called back and talked to my salesman who actually KNOWS the 300C [
] and he had never heard of the RKE battery either. The service dept. was gone for the weekend, by this time, so he is going to check on it and get back with me on Monday.
Is this a common battery that I can get from the drug store battery rack?
Is this a great forum or what?!?!?!? Got the answer I needed with only a short search.
