I have a similar problem, the key fob doesn't work. I have replaced both the GM3 and the antenna modules with a new ones. Still can't initialize the key fobs. I have tried to program the key fobs by all a different kind guides what I have found around the net...

Yesterday I replaced a GM5 module to our e46 (central locking problems) and there was no anykind problems to initialize the key fobs with the new module...
