Key/central locking issue
So I am having an issue with my central locking, I did a bit of research and ended up buying a key on eBay which came with a new rechargable battery,I transferred the guts to it and it didn't solve my problem, the key won't open the doors remotely although it does work to unlock the doors via the driver door lock and it does start the car. When I bought the car it only came with the one key too so I have no back up.
I have read that if it works the locks via the key in the driver lock that it is not a gm5 module problem, anyone have experience with this or have resolved an issue like it? I can't be the only one here who's experienced this.
