Escape From Duckov’s Mechanical Key is a simple but mission-critical item. It’s primarily used to open vehicle cabs and certain locked containers on the Ground Zero map, and it’s commonly acquired inside the bunker safehouse either from a vending machine or from an interior shelf. The key is one of the few items that players can reliably obtain without risky outdoor looting, which makes it especially valuable for early quests that require a specific locked container to be opened.
Mechanical Key uses
The Mechanical Key is an in-game item that unlocks car doors and truck cabs. It’s most commonly required for the Bronze Pocket Watch quest (given by Xavier), where the objective is to unlock a tanker truck cab on Ground Zero and retrieve the pocket watch inside. That watch must then be delivered to the quest giver for experience and money rewards.

How to get the Mechanical Key
There are a few reliable ways to get your hands on the Mechanical Key in Ground Zero. The most straightforward method is by buying it from the vending machine inside the bunker safehouse.

It could be found listed as a purchasable item for around 660 in-game currency, making this the quickest and most dependable option.
Alternatively, you can try checking the bunker shelves or storage areas. Look around the top-left shelving near vendors inside the base — several players have found a Mechanical Key sitting there as part of the base loot pool.
Lastly, it’s also possible to find the key randomly during raids. Keep an eye out while looting jackets, drawers, and car trunks across different maps. Although this method isn’t as consistent as buying it from the safehouse, community reports confirm that it can still appear as random loot.
