How to Clear out Encryption Keys on a Motorola XTS5000

The Motorola Astro XTS5000 is a handheld 2 way radio popular with government agencies including police, fire and military organizations. The radio allows for encrypted communication with the use of the optional key variable loader (KVL). To protect the encryption keys, users can delete the keys from the radio’s memory. This is called “zeroization.” Once you delete the encryption keys, you will be unable to receive encrypted transmissions until the keys are reinstalled, but other stations will still be able to hear your unencrypted transmissions.
1Turn on the radio.
2Press the right arrow on the four-way navigation panel below the LED display until “ERAS” appears in the display.
3Press the key below the display, that is directly below the word “Eras.” There are a total of three selection keys below the display. This will bring up a menu that gives you the option to erase a single key (Sngl), all keys (All) or to abort the zeroization (Abrt). Press the button that lies below your desired selection.
4Select either “Yes” or “No” by pressing the key below your desired selection. If you press “No,” you will return to the previous menu. If you press “Yes,” the key will be immediately deleted.
5Select a single encryption key by using the left and right arrows to scroll through the keys, after you select “Sngl” on the previous menu.
