Hey,

So the remote on one of my old keys decided to stop working, so I bought a new flip key as replacement. Unfortunately, the locksmith screwed up the cutting of the blade, so I ordered a replacement case that included an empty blade, without all the electronics in it. This new key doesn't have the transponder chip in it either, so I need to take it out and transfer it to my new key. I have split the key into its top and bottom parts, but can't figure out how to take apart the top part further.

EDIT: I managed to solve it. There was a screw under the Mazda sticker.
