Schlage does not recommend cutting the L or LP section key blanks in the field. Below are some details.
Non Primus:
In the classic family of keyways the "L" key section is the highest level key. When a 35-100 or 35-101 is specified with an "L" section then stainless steel blanks are supplied. There is no option for the standard material. The thickness of the key is very thin in order to fit into other keyways so it is made out of stainless steel to prevent breakage. Consequently, the key may damage cutters in the field, so we recommend that all "L" keys are ordered as cut keys from the factory (see note below). If a key is cut in the field then a rotary style machine must be used. Non-Primus keyblanks in the "L" key section are available in the Pricebook.
Primus:
The equivalent to the "L" key section in Primus is "LP". The thickness of the LP key is very thin in order to fit into other keyways so it is made out of stainless steel to prevent breakage. Consequently, the key may damage cutters in the field, so we recommend that all "LP" keys are ordered as cut keys from the factory. If a key is cut in the field then a rotary style machine must be used.The LP key blank 35-171 LP is available in the price book.
