1. A thin piece of metal such as a straightened-out paperclip or small flat-head screwdriver.
2. A can of compressed air.
3. A lubricant, such as WD-40 or graphite powder.
Procedure:
1. Insert the thin metal piece into the keyhole and try to gently pry the stuck key out. Be careful not to damage the keyhole.
2. If the key does not come out, use a can of compressed air to blow into the keyhole. The burst of air may dislodge the stuck key.
3. If the key is still stuck, apply a small amount of lubricant, such as WD-40 or graphite powder, to the key and insert it back into the ignition. Try turning the key back and forth gently to loosen it up.
4. If the key is still stuck, it is best to take your car to a professional locksmith or a Renault dealership to avoid any damage to the ignition system.
