1. An assembly comprising a medicament delivery device and a usage management module,
wherein the medicament delivery device comprises:
a housing constructed to accommodate a medicament container;
a plunger rod configured to operably act on the medicament container upon activation;
a delivery member guard slidably positioned within the housing such that distal movement of the delivery member guard activates the medicament delivery device; and
a blocking element that prevents the delivery member guard from activating the medicament delivery device,
wherein the usage management module comprises:
an outer housing and electronic circuitry positioned within the outer housing and configured for operation by a user, where the usage management module is attachable to the medicament delivery device; and
a key arranged on either the medicament delivery device or the usage management module and a lock arranged on the other of the medicament delivery device or the usage management module, where the key is configured to engage with the lock only when the usage management module is attached to the medicament delivery device, where the attachment causes deactivation of the blocking element to allow the delivery member guard to move distally,
wherein electronic circuitry comprises a monitoring circuit that monitors the use of the medicament delivery device.
