Abstract
Disclosed are methods and devices for securely updating firmware of locking devices. One method includes receiving a lock identifier from a locking device; determining that the lock identifier is associated with a user profile by comparing the lock identifier to a set of lock identifiers; receiving a firmware update packet from a server, wherein the firmware packet is encrypted by a lock key; transmitting the firmware update packet to the lock; decrypting the firmware update using the lock key; validating the encrypted firmware update; and installing the firmware update.
