Réponse à : « What happens if you pull the key out too soon? »Hopefully, the problem is just that you haven't put the pins back in the correct order. Keep trying with the key in the cylinder until they are flush with the top. The other potential problem is that you let the top pins fall out. To fix this, you need to pull off the metal spring clip over the pins and, with the cylinder containing the proper pins in place, replace the top pins and springs. Put the clip back on, and you should have a working lock. You may need to purchase new pins or talk to someone with a ready supply.
