Change the key shell on Dacia Logan

Before you start anything and even before ordering the repair kit, check that the switches are not damaged.

in red, switches ok, the repair will be simple

in yellow, switch hs, the repair is possible but it will be much more delicate and will not be covered here

Also make sure you have a working spare (a programmed key that starts the car). This is a precaution, a plan B, in case things don't go as planned.

unscrew the blade retaining screw with a small Phillips screwdriver

then remove the blade by pulling

Insert a small flat screwdriver into the notch at the corner of the key and turn it 1/4 turn clockwise to separate the two parts of the shell

At this stage you can clean the printed circuit but you must use a contact cleaner (if you don't have any, reassemble as is)

This circuit board also manages the immobilizer. If you use an inappropriate product or even worse, if you scratch it, you can make the key (and the car) unusable.

on the lower shell, put the new battery in its housing by pressing on it and check that it is properly in place

The battery is held in place by 2 small plastic tabs.

on the upper hull, put the printed circuit in place (there are centering pins)

put the two parts face to face and pinch to clip them

Replace the blade by pushing it into its housing until it stops.

If the kit provides a new blade, it can be professionally sharpened. That said, it is entirely possible to reuse the old blade.

tighten the blade retaining screw with a small Phillips screwdriver
