I have lots of cores to pin, can Oak pin them for me?

No. Each keying system utilizes specific pins as well as key cut depths in order to keep the systems secure from one another.

Every key that you expect to work in the core should be input into the calculator. You MUST have a CT and Operating at the very least. For Cross Key(X-Combination) cores, all keys that are expected to work should be added.

There are a plethora of reasons why this might be the case but having pins mixed throughout your pinning kit is the highest probability problem. Also, having keys that are aged inserted in cores that are new can periodically cause problems if the keys are severely worn.

If these possibilities are confirmed to be incorrect, there are a handful of other things that could be causing it. Don’t hesitate to give us a call, we would be happy to see how we can help troubleshoot with you!

In the situation where you are missing a pin, you absolutely cannot stack smaller pins to make it. (I.E. missing a 6 and stack a 4 and 2).

Doing so will create additional shear lines in the core, allowing unintended keys to potentially work the core. Never substitute pins in any way shape or form as it will always have consequences.

if you have it, we’ve seen it.
