If your front door locks are starting to act up and not work as they should, be sure to replace them right away. While it is a fair amount of work to replace the front locks on the Audi A4, it is still easier than being locked out of your car, or having to climb over another passenger.

To begin, you will need to remove the front door panel and component carrier. Please see our article on removing your rear door panel and component and complete the work there before starting this project.

Look inside the upper rear section of the door between the outer and inner skin.
Figure 1

Look inside the upper rear section of the door between the outer and inner skin. You will see a small Teflon clip with the door lock pull in it. Take a small flathead screwdriver and push the plastic towards the outer skin and off the pull rod (red arrow).

You can slip the pull rod out from the door handle (red arrow).

This photo illustrates the disconnected rod (red arrow) as well as the plastic protective shield around the lock (yellow arrow).

This photo illustrates the disconnected rod (red arrow) as well as the plastic protective shield around the lock (yellow arrow). You are going to need to free the protective cover from the doorframe, but it is easier to do once the lock is free.

Use an 8mm 12point and remove the two bolts holding the lock to the door (red arrows).

Use an 8mm 12point and remove the two bolts holding the lock to the door (red arrows). Make sure to have the socket well seated in the bolts before you remove them, as there is some blue Loctite on the bolts. You do not want to strip them

With the lock free, take a long flathead screwdriver and pry the protective cover from the door (red arrow).

With the lock free, take a long flathead screwdriver and pry the protective cover from the door (red arrow).

You can now pass the lock mechanism, pull cable and rod out through the door as one piece.
