Need key blank for master pro series padlocks

I have a few different Master Lock pro series padlocks 911 and 6121 that I want to make new keys for.
The cylinders are the same crimped type and are 6 pin cylinders with 5 chambers filled.
I would like to add pins to make them 6 pin locks but cannot for the life of me searching on line find which key blanks to use.
I have attached a photo of the keyway.
Thanks in advance for any help.

You have a restricted keyway there. You are not going to find those anywhere. Time to replace the core.

Problem solved.
In case anyone else is interested.
An M19 key fits the keyway and filed the shoulder back to make it work for a 6 pin cylinder
