Vehicle is a 2008 Dodge Avenger with 2.4L 4 cylinder engine, 4 speed automatic transmission, 65000 miles on the odometer. The security lamp in the instrument cluster has begun the habit of randomly illuminating for about 10 seconds and then turning off while the vehicle is being driven. At the same time the green letters and numbers that indicate the PRNDL and odometer reading numbers will go to bright illumination.

The owner's manual indicates that there is a problem with the vehicle electronics and the system needs diagnosis. Before I "bite the bullet" and pay a diagnostic service fee, I am wondering if others have encountered this phenomena? On a wild guess I told the driver to switch and use the other key fob with integrated remote in the slim chance the problem is with the electronics in a particular key. But that is just a guess. Ideas???

We have been using an alternate key fob with built in remote. This unit is newer and has a fresh battery. The security lamp does not blink intermittently. I believe the intermittent blinking was caused by the system sensing a low battery in the remote and flashing the lamp as a signal. I did not have the system scanned for a diagnostic code. It seems silly to pay $75 - $100 in diagnostic fee to just be told a $4 battery in the keyless remote needs to be replaced.
