Methods and systems for facilitating exchanges of keys between individuals across multiple locations are provided. Each key set is assigned a unique key identifier. The key identifier is encoded on a key chain attached to the key set. A key set is picked up or dropped off at a key exchange center and is scanned to read the key identifier. The key identifier is relayed to a key exchange server which tracks key locations. The key exchange server verifies that an individual is authorized to pick up a key set and provides instructions to a device at the key exchange center to enable access to the key set. The key exchange server coordinates drop-off of a key set by updating the key location associated with the key identifier at drop-off and providing instructions to a device at the key exchange center for storage of the key set.
