I have a 2009 JK Unlimited with Auto, remote starter, and Sentry Keys. Last week the keys (oddly)will not lock the doors immediately after turning off the ignition (but the power locks will work from the switches inside the car), and if you try to restart the engine it will shut down after 3 seconds (for three times, then will start normally). If you wait about 5 minutes the keys will function properly again in all respects. I have replaced the key batteries, and the dealership has replaced and reprogrammed the keys...no success. Has anyone seen this before?? Thanks!
