A double-keyed deadbolt is not illegal in most places, but some local building codes or fire safety regulations may restrict or prohibit their use, especially in residences. These locks can pose a safety hazard during emergencies because a key is required to unlock the door from the inside. Always check your local laws and regulations before installing a double-keyed deadbolt.
