This is a blank key for a VW MK4, Including Jetta and Golf. You must add your own Bumps copied with calipers from your key. I highly recommend this is printed in Virgin ABS at the highest possible layer resolution and that the key is only used for emergencies as there are many factors that could contribute to a weakened key (Cold Snap). I have printed this and it works well. please be careful when using this as the key may snap off in the lock cylinder. I also want to specify that i printed a few keys ahead of time with the same print setting to try and snap, to be sure i had good setting and strong material! Be sure to sand and remove excess plastic.
