I believe the answer is Sebaceous gland. Sebaceous glands are microscopic exocrine glands (glands that secrete and produce substances using ducts to an epithelial surface). They are found in the skin and secrete oily or waxy substance called sebum. Sebum functions to lubricate and waterproof the skin and hair of mammals.
The lock an key analogy is used because each enzyme has specific substrates that fit into it. This is like how locks only work with a specific key. The enzyme is the lock and the substrates are the key.

This analogy is not perfect because there are often multiple substrates for each enzyme reaction. It only takes one key to turn the lock. The reaction is also taking place between the substrates themselves and not the enzyme. In the lock and key analogy, the lock is affected by the key, but in an enzyme reaction, the substrates are affected by the enzyme.
Hope I’ve helped ;)
