Hey so just purchased a black sline quattro a3 five door and been having some issues with door locks. Drivers pass door wont lock normally so then the car wont beep saying all doors locked and if it does decide to lock then u cant get it open again unless u pull handle from inside sometimes this happens with the front drivers door as-well the car did come with and aftermarket data-start fob that was dead batt when we got it and still Havant put a battery in it and im wondering if i should just be removing the whole aftermarket thing
