Entry System

I have a 1995 Intrepid. Some how the entry system got armed (Headlights are flashing and the car will not start) Last time I had this happen we had to unlock and lock the doors using the transponder. SInce that time the transponder has died and we no longer have it. I have unhooked the battery for 5 days and that did not help. Does anyone know of a way to bypass this system ?

Have you tried locking and unlocking the driver's door from the outside with the key?

ya that did not work.
