Great caution because it is defective. Now if it happened to be my piece, I don't know. When I tried to assemble it, I saw that the screw couldn't screw in, even though the blade seemed to fit well. However, because the two plastic parts were tightly stuck together, I left it like that. When the next day I tried to start the car (and even though the key fit well in the ignition), it didn't move forward. It made the noise as if it was about to start, but it didn't... Honestly, at that moment my mind didn't go to the key. Because I had to leave for work, I left it like that with the intention of calling roadside assistance after a few hours. However, luckily during my work, it crossed my mind that maybe the key was to blame. So as soon as I returned home, I tried the second key, which started the car.
