How long does it take to get a key to turn in the ignition on a 10 cut system? Example a 2015 Chevy Silverado.

The whole process does not take long at all. You will simply try keys from the four rings of 8 keys. One of those keys will turn in the door.

No more than 10 minutes if you have to try all of the keys. Once you find a key to turn in the door then you will find one of only four keys from the OCTOKEY Chart to get the ignition to turn.

Will Octokeys work on the GM8 cut system?

YES!  We now have an OCTO-8 KEY SET. 

It is a tryout set that will work the doors and the ignitions on the 8 cut system

Can I just copy the OCTOKEY that I found to turn the ignition?

That is a good question. They OCTOKEYS are tyrout keys cut with 

half depths. It is best to just follow the instructions to get a working key.

Can I use the OCTOKEYS to open  GM vehicles?

Absolutely.  On GM 10 cuts systems it is a must!  It is non-invasive. It is quick. Many of the newer GM cars and trucks that use a PROX system use the same door tumbler placements that the OCTOKEYS work on!. Makes car openings super easy! See the VEHICLE APPLICATION GUIDE to see which door locks the OCTOKEYS will work in. You can use the 10 cut set OR the JTD set on the 10 cut system. 

On the 8 cut system there are many keys to try. 128 both sides.

I went through the door set and did not find a key that turned in both directions. What should I do?

In rare cases this may happen. Do not worry. You will still get a key to turn in the ignition! For each key that you did find that turned in the door only in one direction go ahead and use CHART #1. You will find a key to turn in the ignition. Once the ignition is turned simply remove it to get the keycode.  CLICK HERE FOR VIDEO

Octokeys have been out now for over a year and here are some of the things we have found out to make it easier to use!

  1. There may be MORE than 1 key that will turn both directions in the door. If you find a key that turns in both directions and you try the ignition keys and they do not turn, finish testing the doors keys to see if there is another key that turns both ways as well. Lubricate the lock you are working on.

  2. DO NOT jiggle the keys in the doors. Just try them while turning left and right. Do not force.

  3. Some door locks are worn as well. While trying the doors keep track of any key # that turns in one direction. Use this/these keys if there is more than one, to determine the ignition keys to use from the instructions.

  4. The 10 cut ignition locks wear out quickly. It is a good idea to use a pair of vise grips to add a little more torque while trying the ignition keys. Not enough to bend but just a bit more torque.

  5. Remove the ignition and CUT BY CODE. IF you cannot make sense of the code or if lock is worn simply remove the tumblers to see the depth number stamped on it. Replace any badly worn tumblers. Removing the lock is the easiest and quickest way.
