The Rizr Z3 uses a technical form factor, where the user can push on a plastic "push bar" located under the screen in order to open the phone. When opened, the top portion slides upwards, revealing the standard keys (including numeric, star, and pound keys). These keys are covered when the phone is closed, but the remaining keys, including the side keys, can be used normally once the keypad is unlocked; such keys can be set to automatically lock shortly after the device is closed to prevent accidental activation when in a purse or pocket.
