Yes, all guests entering the Disneyland Resort theme parks and the Downtown Disney District must pass through a security screening process that includes metal detectors. Disney utilizes advanced, high-tech scanners (often Evolv technology) that allow most guests to walk through at a normal pace without removing keys, cell phones, or wallets from their pockets. These systems are designed to identify prohibited items while ignoring common personal belongings. However, if the system flags a potential concern, a security Cast Member will direct the guest to a secondary screening area for a manual check with a hand-held metal detector wand and a more thorough bag inspection. This security "bubble" encompasses both Disneyland Park and Disney California Adventure, as well as the shopping and dining district, meaning you only have to clear security once to move between these areas. To speed up the process, guests are encouraged to remove large metal objects like umbrellas or heavy battery packs from their bags and hold them out in front of them as they pass through the sensors.
