Theres a key they make with a square head and a ball bearing on the bottom of it under the last few teeth. Im trying to find a blank of it but Cant seem to find it anywhere... searched there whole site.. the lock looks like the ML2000 model but cant be sure.
If anyone can find this key thank you very much

the head of the key looks exactly like http://www.leedistributors.com/hardware/keys/arrow-k2-k3-5-pin-key.html

Pyramid high security/restricted system...

Sounds like it isn't your lock and that it is a Pyramid Patented/Restricted system which you will not be able to find keyblanks for anywhere...
