The HD COT2 Precut Window Key is a standard replacement cylinder-style key designed to fit Cotswold espagnolette uPVC window handles.
It is a highly common profile frequently cross-referenced by alternative manufacturing blanks and codes, including KWL5, PV600, ES900, and HD Hook WL013.
Instead of replacing entire handle mechanisms, you can use these precut keys as a direct drop-in replacement.
Because COTS covers multiple key variations, you will need to verify if your specific lock requires a COT1, COT2, or COT3 pattern.
