We had the same problem about 3 years ago and replaced the module.

Now we have a new problem. Security system Lockdown - Doors won't unlock/lock with the key fob, car won't start, Little green light on the console turns on, flashers blink.

We can put the car in neutral to tow.

Mechanic has tried replacing the batteries in the Key FOB, programming the fob and synchronizing the fob transmitter. Nothing has worked.

Anyone have any additional things to try?
