Engineering vehicle key management method, device and system and storage medium

The invention provides an engineering vehicle key management method, device and system and a storage medium, which can identify a user borrowing record in a login request by responding to the login request of a first side network terminal based on an existing locker, and further determine whether a user is a new user or an existing user. And when the identified user is a new user, displaying a key retrieval interface in the first side network terminal. And in response to a selection operation of the user on the target available key, sending a borrowing request of the target available key to the second side network terminal. And sending a door opening instruction to the storage cabinet for storing the target available key. And when the identified user is the existing user with the vehicle borrowing record, displaying a borrowing record interface while displaying a key retrieval interface in the first side network terminal. And determining the borrowed key storage cell represented by the target borrowing record
