I got the key new but?

I bought a new key with a chip, then I replaced the end of my key with the one I bought, there was a new chip inside, I bought a chip, I couldn't introduce it to the car.

First of all, welcome to our brother, you will either go to the auto keymaker or introduce the key to a place with original peugeot planet software. Because it needs to be introduced to the tool and delete the old key
