Crazy Dave's Car Key is an item obtained at the end of Level 3-4 in Plants vs. Zombies and belongs to Crazy Dave. In the iOS version, it was removed in a later update, due to the addition of the Zen Garden. It was replaced by obtaining bacon, and bacon was moved to Level 3-4, to allow for the Zen Garden to be unlocked after Level 5-4.
When obtained, it unlocks the trunk of Crazy Dave's car, which unlocks Crazy Dave's Twiddydinkies. If the player does not have the full version of Plants vs. Zombies, they will only be able to access a few things in the shop. This is also the last thing a player can unlock if they do not have the full version. The shop sells all upgrade plants, as well as the Garden Rake, Pool Cleaner, bacon, Wall-nut First Aid, Imitater and various Zen Garden items. On the iPhone, iPod Touch, and iPad versions, the bacon is obtained instead of Crazy Dave's car key since Crazy Dave's Shop is already open to buy Mini-games.
- It is unknown why the zombies carried Crazy Dave's Car Key if it is owned by Crazy Dave.
- The car key appears to be bent and dented.
