To use the OCTO 8 HU100 Tryout Key Set, follow these steps:

1. Start by trying each key in the lock. Use a small pair of vise grips to add a little more torque, but be careful not to bend the key. The vise grips should be used as a handle, not for up and down motion or jiggling of the key.

2. Turn the key left and right, trying both sides of the key. Proceed along until you find a key that turns. It is recommended to try the ignition lock if the car is equipped with one.

3. Once you find a key that turns, peer into the lock to determine the location of the first tumbler that moved. This will help you identify the correct key cuts.

4. Match the key number on the OCTO-8 KEY CHART provided with the set to get your lowest cuts. These cuts are indicated as 1 depth and 3 depths. However, it may be necessary to adjust these cuts to obtain a working key. For example, you may need to adjust a 1 depth to a 2 depth or a 3 depth to a 4 depth, depending on your skill and the lock.

5. If you are working on an ignition lock, once you get the ignition to turn with an OCTO-8 key, turn it to the start position, depress the retainer, and remove the key to get the key code stamped on the cylinder.

Please note that the OCTO-8 Keys are designed to work on door locks and ignition locks of GM HU100 keyways on the 8 cut system. They will not work on the 10 cut system ignition locks (which are black in color). The 8 cut ignition locks are always silver. These keys are specifically for vehicles using the HU100 key on the "Z" codes series.
