Hi first time on here, need help, i have a 2013 xf and the drivers door would not open every time when using the remote. So i bought a new lock assembly, followed the info and u tube and after about 3 hours put everything back together. When i work the remote now the drivers door will not lock, after one press of the remote all the doors make a noise and lock, After 3 seconds there is a double beep from the alarm. when i open the drivers door the alarm goes off. Can anyone help it is doing my tree in?
