You don’t need to take the holder apart. Just twist the metal back off the AirTag to replace the battery; the AirTag can stay in the holder.

But if you do want to take it apart, remove the key ring and twist the two halves of the holder.

i have the same holder and it’s a turn mechanism. Just hold the back piece and turn the front piece and it should unlock and separate.
