I’ve changed over out stations with no joy

Dash first says press remote then key code, everything worked fine until the battery went flat, I’m assuming because the drivers door is dead it’s not excepting the code

HI ALL, new to this so not sure how it works, anyone live in the langport Somerset area, drivers door dead, no window or mirror, got key code lockout, tried putting the code in but nothing, as the door is dead I don’t suppose it will take it, Dave
