The Ultimatrix Security Keys are two special keys to used to give access to otherwise locked DNA of certain aliens in the Ultimatrix. In order to prevent himself, and by extension, Albedo, from becoming certain transformations like Alien X, Ben had their DNA locked and the keys created to return access to him in case of an emergency. Ben gave the keys to Gwen and Kevin.
The security system and its keys fell out of use when Ben received a new Omnitrix from Azmuth. The Omnitrix so far does not have something similar to the Ultimatrix security system, and Ben can become Alien X freely.
The two keys are exactly alike, a medium gray key with a round toe marked with the symbol of the Ultimatrix.

The keys need be placed in slots on the side of the Ultimatrix's dial, and then turned, thus overriding the Ultimatrix Security System and unlocking the blocked alien DNA.
It is used to prevent Albedo from activating it and Ben from transforming into Alien X by accident, thus preventing one of them from accessing Alien X's abilities and the other from being trapped in Alien X.
- Both keys were held by Gwen and Kevin at all times in case of emergency.
