Article perfectly compatible with the original plip (C4 sedan in May 2005) Fast delivery. The electronic card fits perfectly into the case. The blade replacement required for not only the hands inches and a minimum of tools. The notice is not given I'll make you a: Do this: 2mm pin hunting a small hammer a vise with a cloth, a way screwdriver and tweezers. Start with the old key to train a lower risk. To remove the blade placed in a cloth (to avoid damaging it) and tighten flat horizontally in the vice. Slightly turn the housing to allow access to the pin. Place the pin hunting (or a blunt nail) on the pin and lightly knock on the hunt to remove the pin. Turn the blade of 1/4 turn for the slot in the top box. Place the tip of the screwdriver blade angle and its articulated metal support it parallel to the blade, and strike at the end of the handle with a hammer to break the blade support. In this way, when pressing the metal, there is no risk severe damage to both the joint in the housing. Most of the bad comments are after breaking the box forcing the plastic to remove the blade. Do the same with the new case and reverse the blades. On the one hand use the tweezers to hold a clamp to hold the pin in place with the other hand push the pin with a hammer or use a third hand to hold a hunting bigger pin to the pin flush with the metal. Good DIY, I spend so much time writing this comment has replace the blade.
