First, using an A1 decoding block, I removed the pins from the core.
Here are the pins. I measured them to get the values to use to create the keys for this core.
I then reloaded the pins into the core.
I cut keys and tested to make sure control and master keys work.
After all was proven, I capped off the core.
Then I placed the core back into the housing.
That's basically it. For pros, how long would it take to dump the core and make keys?
