By following the steps carefully, you can remove each part of the key housing smoothly, which is especially useful for key repair, shell replacement, or internal component work.

Step 1: Remove the Silver Side Cover

First, locate the release button on the back of the key.

There are two locking clips on the back cover, located at Position 1 and Position 2.

1. Turn the key on its side and place both thumbs on Position 1

2. Push the black cap upward with your thumbs

3. When you hear a “click,” the Position 1 locking clip is released

4. Next, place both index fingers on Position 2

5. Push the cover in the opposite direction

6. When you hear another “click,” the Position 2 locking clip is released

At this point, the back cover can be removed without any damage.

Step 3: Remove the Front Cover
