Key Chain LEGO sets
837 official sets in the Key Chain theme.
The Key Chain theme includes 837 official LEGO sets in our catalog. Each listing links to a full parts inventory, minifigure breakdown when available, and official build manuals you can read in your browser.
Key Chain sits under the broader Gear theme on LEGO's product line. Collectors often browse both levels — parent themes for overview, subthemes for specific eras or licenses.
Use the grid below to explore by release year, then open any set to verify loose parts against the inventory or check market estimates before buying or selling.
With a large catalog footprint, Key Chain is a common source of bulk-lot finds. Sample random pieces from mixed bins and identify them against set inventories here before pricing — licensed subthemes and retired minifigs often hide in generic "assorted LEGO" listings.
Collector tips
- → Sort bulk lots by checking printed tiles and minifig torsos first — they often carry more value than common plates.
- → Compare color variants on part pages before listing; the same mold in different colors can have very different market prices.
- → Open build manuals on set pages to confirm bag contents when rebuilding incomplete copies.
