Have an '02 Sonata with keyless. Went for gas today (wife and I), we both got out of the car and shut the doors. The car locked by itself with the keys in the ignition. Had to have the neighbor come with the spare set. The remote (spare) would not work, the spare key did. Once we got in, everything worked okay the spare and the regular remote. Once before the car locked by itself and the alarm went off. The wife had the keys at the time and this was no problem. My guess is there must be some kind of a control module that has a problem. Can anyone shed some light on this, I'd like to get it fixed if it's not a fortune. As this is the wife's car and she doesn't like these kind of surprises.
Thank you all, Bob
