Just bought this car last week (04), the transmitter is not unlocking/locking the doors/trunk of the car; I have to manually lock/unlock the doors using the key. The key works fine when starting the car.

I tried the DIY method to program the key (in the huge thread), but it still does not program the key fob's remote to work for wireless entry. The car is detecting that I am pressing the buttons on the key fob, however, because the right blinker will flash but the lock/unlocks mechanism still won't work. I think I read in another thread I may have to replace the battery. Anyone know for sure?

Thanks all
