Regarding expiration date display, which statement is true?

• A. All keys display the expiration date on the TKL.
• B. Some keys display the expiration date.
• C. None of the keys display the expiration date on the TKL.
• D. The expiration date is displayed only on the battery module.

Answer: (C)

Expiration date visibility on the TKL isn’t a feature; the keys don’t show service-life data. The TKL interface is designed for quick access and function labeling, not for displaying expiration information. Because no keys carry or present an expiration date, the statement that none of the keys display the expiration date on the TKL is the correct one. Options suggesting that some keys, all keys, or only the battery module would show an expiration date would imply a display behavior that the TKL’s design does not provide, so they don’t fit. If you need expiration information, it’s handled outside the TKL interface, such as through maintenance records or separate labeling, not on the keys themselves.
