This post will show you how to assemble Xhorse VVDI BE Key Pro PCB and Benz Smart Key Shell.
Step 1. Remove the Benz smart key shell.

Use a screwdriver to open the shells on both sides and the top of the keychain.
Then break the rest by hand.

Step 2. Install the PCB into the key shell.
First, we need to install the battery, take out the iron sheet above the battery slot, insert the battery and then cover the iron sheet.
Then place the PCB.
Align the top left and bottom right corners of the chip, then close the other half of the key shell tightly, then install the sliding shells on both sides.
Reinstall the top shell, insert the small key.
