Cool additional key functionality

What if you could unlock a chest with a key by holding M2 (like how you'd use a toolbox on a gen).

First, buff Dull keys to last for 10 seconds (from 5).

So, key's can now be used to unlock chests (which take 10 seconds to open).

Chests unlocked with:

• Skeleton keys guarantee an Item rarity of Rare or greater.
• Dull keys guarantee an Item rarity of Uncommon or greater.

Additional key addons:

• Rare addon: Key guarantees an Addon rarity of Rare or greater.
• Uncommon addon: Key guarantees an Addon rarity of Uncommon or greater.

Note: Dull key's would only have enough charges to unlock 1 chest (they would last 10 seconds). Skeleton key's would have enough charges to unlock 3 chest (they last 30 seconds).

Further notes:

So keys would work a little bit like Plunderers Instinct. Keys would also work a little bit like Ace in the Hole too if the addons mentioned are used. However keys would guarantee a certain rarity or greater, unlike Plunderers Instinct and Ace in the Hole.

Keep in mind that keys wouldn't work with Appraisal - only when unlocking chests. They also wouldn't reveal the aura of chests like Plunderers Instinct does.

Note that this change could also be beneficial to killers because survivors using a key to unlock chest(s) are not on gens and are not bringing a Medkit (and are not guaranteed to get one in a chest).

ALSO if you got this far in and like the idea, feel free to think of additional addons that could be added due to this new functionality. Or if you've got suggestions on amendments to this key change it'd be interesting to hear.

Edit: Slight changes. Buffed Dull keys slightly in order to nerf the use of Skeleton keys to unlock chests from 6 to 3. Although of course, survivors could always bring Built To Last, Streetwise and Pharmacy to enhance this build!
