Icons have been helping us for decades, if not centuries. From street signs (Deer X-Ing) to desktop folders, we look to icons to tell us information in quick and concise ways. It only makes sense that this idea would transfer over to the house key...
The Stat Key Company design keys with different icons cut into the nickel-plated metal. Above are their home and heart keys, which we think would be good for designating, well, your home opener and your partner's home (if you've been trusted enough to have their key that is).
Stat Keys are designed to work with Kwikset locks, which you can see here. The keys are obviously not cut for your lock, so once you get them you'll have to take them to your key maker to have them appropriately cut.
