What must be true for an unlicensed person to install a pre-keyed lockset?

To install a pre-keyed lockset, it must be true that the installation does not involve rekeying. This is significant because rekeying a lock typically requires specialized knowledge and skills, which are associated with licensed locksmiths. A pre-keyed lockset is designed to function without the need for rekeying, meaning that an unlicensed person can install it safely and effectively as they are not altering the internal workings of the lock.

The other options discuss employment status, training requirements, and pricing, but these do not directly pertain to the fundamental aspect of the task being performed. The focus on rekeying ensures compliance with relevant regulations that require a licensed individual to alter or reconfigure the internal mechanism of a lock. Therefore, confirming that the installation does not involve any rekeying allows unlicensed individuals to engage in this type of work within the legal framework set by the licensing requirements.
