House of El Command Key

The House of El Device or Kryptonian Command Key was a tool created by Jor-El that was sent to the planet Earth along with his son Kal-El. It can be used to access Kal-El's Spaceship   and the Fortress of Solitude.

This device would be influential in helping Clark Kent realize who he was and what he could do to protect the planet as the hero, Superman.

Early History
Jor-El formed the Command Key on Krypton just before placing his son Kal-El in a ship that would be sent to Earth   where he would escape Krypton's destruction. He put the Key in the ship with Kal-El and launched him to Earth.

The ship landed in Smallville, Kansas in a field of the Kent Farm. The ship was found by Jonathan   and Martha Kent    who took in Kal-El as their own and hid the ship beneath their barn.

When Kal-El, now named Clark Kent was 13, Jonathan showed him his ship and the Command Key.

When Clark grew into adulthood, he heeded his father's words and went on a journey to find more about his origins and took the command key with him and wore it around his neck. Whilst out on a fishing boat in the pacific ocean, a signal was sent to the key from a source on Ellesmere Island, Canada. Clark followed the signal and used his X-Ray Vision to find a Kryptonian vessel   under the ice. Using Heat Vision, he tunnelled down to find the ship.

Physical Appearance
The device is small in diameter and has a top that's in the design of the House of El crest.
