The keyless entry would not work on my 2003 Town Car. After checking a number of things, including seeing someone else with the same problem, I decided that my DDM module was bad. I was able to find a replacement module, and installed it. It had the exact same number as the old one. It did not work. After reading my shop manual and trying many things, I found out that it has to be reprogramed using either a Worldwide Diagnostic System 418-F224 or a New Generation STAR Tester 418-F052. I am trying to find a repair shop that has this test unit to get the new module reprogrammed. Does anyone know of an auto repair shop near Riverside, CA that may have this piece of test equipment?
