FYI For everyone. Got fed up, so took it to the dealer. They replaced the Transponder Bypass... and low and behold, it fixed the problem!
I also had a Check Engine (MIL) lite on, with code P0420 (TWC). So, luckily, the emissions control is under warranty for 8 years, or 130K Km. I have 120K, so the damn thing was replaced....
Working like a charm now! Just thought I would let every one know. Thanks to all for the inputs.
