The present application discloses an intelligent lock enabling the replacement of electronic components using a key, comprising: a housing; an electronic component, which is detachably mounted on the housing; a locking assembly, disposed inside the housing and configured to lock the electronic component onto the housing; and a key, adapted to the locking assembly and controlling the locking assembly. By controlling the locking assembly with the key, the intelligent lock allows for quick installation and removal of the electronic component, facilitating maintenance operations such as repairs and battery replacement. Moreover, it enables switching between a keypad electronic lock component and a fingerprint electronic lock component, thereby meeting diverse user requirements, reducing workload, and minimizing resource waste associated with the need to repurchase door locks.

A vehicle-mounted apparatus comprising: a main body portion; and an electronic key accommodating portion that accommodates an electronic key of a vehicle and is attachable to and detachable from the main body portion, wherein the electronic key accommodating portion includes a switching unit that switches detection states of a first detection unit and a second detection unit according to an attachment or detachment operation of the electronic key accommodating portion to or from the main body portion, the first detection unit is provided in the main body portion for detecting an accommodation state of the electronic key in the electronic key accommodating portion, and the second detection unit is provided in the main body portion for detecting an attachment or detachment state of the electronic key accommodating portion with respect to the main body portion.

It is provided an electronic lock (20) comprising interface circuitry (4) and a microcontroller (5); wherein the interface circuitry (4) is configured to dynamically respond to a query signal from a conductively connected electronic key (2), to enable the electronic key (2) to detect presence of the electronic lock (20); wherein the interface circuitry (4) is further configured to decode incoming data from the electronic key (2) for forwarding to the microcontroller (5), and to encode outgoing data from the microcontroller (5) for forwarding to the electronic key (2); wherein the interface circuitry (4) is further configured to control when power is transferred from the electronic key (2) to the microcontroller (5); and wherein the microcontroller (5) is connected to the interface circuitry (4) for communicating with the electronic key (2) and for receiving power from the electronic key (2).

A key can be configured for interfacing with a dispenser in a commercial facility, the key can include a body and key hardware configured to unlock the dispenser. A beacon device can be incorporated into the body and configured to transmit beacon data including an identity of the beacon device. The key can be used for maintenance of commercial facilities by maintenance personnel, wherein the commercial facilities include consumable product dispensers that require periodic refill. Maintenance can include interfacing a receiver device incorporated in a product dispenser with a beacon device incorporated into a key configured to unlock the product dispenser, interfacing the receiver device with a server system to transmit the identity of the beacon device to the server system, and identifying, by the server system, an identity of a maintenance personnel that unlocks the product dispenser based at least in part on the identity of the beacon device.
