Write Protect and the Owner ID (Keystone Concept)

Write Protection for a radio is used to guard against unauthorized codeplug modifications in the event of radio theft. The radio's write protect status is tied to the radio's Owner ID, both of which may be viewed and/or defined with two distinct CPS methods: Codeplug Open or Codeplug Closed.

For both methods, the write protection process begins by creating an "Owner ID" Advanced Key in the Advanced Keys Administrator program.

A radio's Write Protection can also be cleared by an authorized Motorola Service Center.

When Viewing the radio's Write Protect Status, Key Type and Owner ID:

An "Unlimited Access" Advanced Key must be loaded in the CPS (see the System Key Report) and also attached to your computer's USB port.
Click the Query Radio button (from the Query / Update Radio Date page).

When enabling or disabling the radio's Write Protection:

An "Unlimited Access" Advanced Key that has a "System ID" that matches the radio's current Key Type and Owner ID must be loaded in the CPS (see the System Key Report) and also attached to your computer's USB port.
Make the appropriate Write Protect field selection (from the Query / Update Radio Date page).
Click the Update Radio Data button.

When updating the Key Type and / or updating an Owner ID,

An "Unlimited Access" Advanced Key that has a "System ID" that matches the radio's current Key Type and Owner ID must be loaded in the CPS (see the System Key Report) and also attached to your computer's USB port.
A "Limited" or "Unlimited" Advanced Key which matches the new Key Type / Owner System ID (if being changed) must be loaded in the CPS (see the System Key Report) and also attached to your computer's USB port.
First select the desired Key Type (from the Query / Update Radio Date page), then select the desired Owner ID from the drop-down list.
Click the Update Radio Data button.

When Write-Protecting Radios and Writing to Write Protected Radios the following must be true:

An “Unlimited Access” and "Write Protect" enabled Advanced Key (see the Advanced Keys Administrator) that also has a "System ID" that matches the Owner System ID or the Owner WACN ID is currently loaded into the CPS (see the System Key Report).

This Advanced Key does not have to be currently assigned to one of the codeplug's Trunking Systems.

The ASK Required field must be enabled.
And then, when actually clicking the CPS's "Write Device" button to Write Protect the Radio, the Key Device containing the Write-Protect-enabled Advanced Key, defined in Step 1 is currently attached to your system's USB port via the Key Device Reader.

Write protecting multiple radios is also possible with the POP25 Batch Programming operation. In order to write protect during Batch Programming, the Write Protect Radios If Write Protected Key is Attached field must be enabled, and the an Owner ID Key match (loaded and attached) must exist for each target radio when scheduling the Batch Programming.

Disabling a Radio's Write Protection:

An “Unlimited Access” and "Write Protect" disabled Advanced Key (see the Advanced Keys Administrator) that also has a "System ID" that matches the Owner System ID or the Owner WACN ID is currently loaded into the CPS (see the System Key Report).

This Advanced Key does not have to be currently assigned to one of the codeplug's Trunking Systems.

The ASK Required field must be enabled.
And then, when actually clicking the CPS's "Write Device" button to Write Protect the Radio, the Key Device containing the Write-Protect-enabled Advanced Key, defined in Step 1 is currently attached to your system's USB port via the Key Device Reader.
