金鑰（下養酌反字書正從門作𨷲前釋教錄已釋傳從竹作籥俗字也亦通用之也）。

金鑰 (the second character has the fanqie yang + zhuo [yuè]; the character books properly write it with the gate radical as 𨷲; already explained above in the Shijiao lu; the transmitted text writes it with the bamboo radical as 籥, which is a vulgar character, though it is also interchangeably used).
