TRYOUT SET FOR HU100 ON 8 CUT SYSTEM
OCTO-8 is simply a tryout set for HU100 8 cut systems. The set consists of 128 keys covering ALL 256 HALF CUT possibilities. There are 16 Rings with 8 keys each.
- Works on HU100 Z series codes
To use you will try each key in the lock. You will want to use a SMALL pair of vise grips to add a little more torque. NOT enough to bend the key. Just use it as a handle. Do not use any up and down motion or jiggling of the key. Do not force key. Turn left and right. Try both sides of the key. Proceed along until you find one that turns. It is best to try the ignition lock if car is equipped.
Once you find a key that turns you will need to determine which side of the OCTO-8 key turned in the lock. Peer into the lock to determine the location of the FIRST tumbler.
Match the key number on the OCTO-8 KEY CHART to get your lowest cuts. These are 1 depth and 3 depths. It is up to you and your skill to adjust these cuts to obtain a working key. (You may have to adjust a 1 depth to a 2 depth and 3 depths to a 4 depth.)
IF working on an ignition once you get the ignition to turn with an OCTO-8 key simply turn to the start position depress retainer and remove to get key code stamped on the cylinder.
