We will start by removing the four Torx T4 screws that hold the rear case.
Step 2 Take off the back cover
After removing the screws we will have to take off the vibrator, which is stuck to the plate and the back shell, before removing it.
Step 3 Remove inner casing
First we will remove the insulating rubber to avoid losing it or damaging it.
Then we will undo the inner casing, very carefully since this is very weak.
Step 4 Keys
To finish, we will remove the security washer and press the button from the inside to eject it.
