Change the battery in the remote - again. I have seen any number of the Chinese-source batteries be defective from the start. If that does not work out, the on-board receiving antenna may be defective - which from your description may be the case -
works only inside the car. There is a You Tube on getting to it and replacing it - looks like a major PITA. Similarly, the module - but the module should be fine if it works at all.
