Attaching, Replacing & Detaching Tags

How to attach, replace, and detach tags from various points in the portal.

The Cognosos portal provides multiple inroads for attaching, detaching, and replacing tags. When a vehicle and tag are attached, it means that tag has been physically placed in the automobile, and both the vehicle and tag have been defined within the system with a relationship between the two. Users with the role of Standard and Administrator have access to this feature.

A tag is a device (e.g., hangtag on rearview mirror) that is placed inside the vehicle and provides wayfinding services.

Attaching or detaching the tags arises from various needs: arrival vehicle does not currently have a tag attached; vehicle has gotten a new tag; a tracker has become defective and needs to be detached and replaced; and so forth. As such, vehicle and tag relationships can be defined from the:

Vehicles Tab - attach or detach from Vehicles list

Vehicle Details - attach/detach tag, replace tag

Tags Tab - attach and detach from Tags list


Best practices indicate that attaching tags should be done through the Logistics Mobile App while user is physically at the vehicle in which the tag is installed. Detaching tags can be done on the mobile app or through the portal.


Vehicles Tab: Attach + Detach

From the Vehicles tab in My Lot either place a checkmark next to a specific vehicle (unattached status) or leave all the checkboxes blank (no selection) and click the Attach button from the Vehicles menu.

The Tag Attachment pop-up window opens. If there was a vehicle selection from the Vehicles tab, the vehicle ID will auto-populate in the Vehicle ID field. If no vehicle was selected, both fields will be blank.

Input the proper value(s) and select Next. Otherwise select the X in the upper corner to abandon the action.

If the input tag has a status of unresponsive, the system will display a warning. Correct any issues with the tag so it is responsive or use a different tag to continue.  


When attaching a tag, ensure that the tag’s battery status is 50% or higher. You can view battery level for all trackers on the My Lot Tags page (Battery Level column) and you can filter the tag list by battery level (normal, low, critical).


Once attached, the system opens the custom details window to input additional details for the vehicle to which the tag is attached. Vehicle details help to ensure that vehicles can be easily located using a variety of attributes and identifying information. The more details, the easier it is to locate the vehicle and to track data that may impact business operations.

Scroll down to access all the available fields. Use the drop-down lists or input values for vehicle details as needed. Add new values to custom fields as needed.

Select Submit to complete the input or Back to change the tag or vehicle ID. When complete, the vehicle/tag information is updated across the portal.

To detach a tag, select a vehicle from the Vehicles table and select Detach from the menu. The system allows only one vehicle-tag detachment at a time so a single selection must be made. Otherwise, the button will remain grayed out.

Select Confirm to continue the process or Cancel to disregard the action. Once detached, the automobile can no longer be tracked through the portal.

This operation removes the relationship between the tag and the vehicle. If you need to continue tracking the vehicle, attach a new tag and ensure the new tag is with the vehicle.

Vehicle Details: Attach, Replace + Detach

A tag may be attached, detached, or replaced directly from the Vehicle Details page depending on the current vehicle status. Access this page through the map or My Lot by selecting the (unattached) vehicle icon or link, respectively.

When a vehicle has the status of unattached, the Vehicle Details page will display the Attach Tag option. Select that option to set up the tag.

Follow the same steps as outlined in Vehicles Tab: Attach + Detach.

When a vehicle has the status of attached (whether located/has signal or not located/lost signal), Vehicle Details shows the option to Replace Tag. This function essentially wraps the detach and attach functions in a single step.

Input a new valid Tag ID (status of unattached, normal battery) and click Next. Continue as described previously.

To detach a tag from a vehicle without replacing it (e.g., car sale) select Detach Tag.

VD Detach Tag Vehicle Details page highlight Detach Tag option

The Vehicle Detachment pop-up window opens. Confirm the detachment. Detaching the tag removes the relationship between the tag and the vehicle. If you need to continue tracking the vehicle, attach a new tag and ensure the new tag is with the vehicle.

Tags Tab: Attach + Detach

Open the My Lot > Tags tab. You may use filter or search to look up and attach a specific device.  

To attach a tag to a vehicle, select Attach from the Tag menu with either no items checked or a specific tag selected. Ensure a sufficient battery level in the selected tag.

In the Tag Attachment pop-up window input proper values into the Tag ID (if no tag selected) and Vehicle ID fields. Select Next to continue.

The process to add vehicle details continues as described in Attach Tag from the Vehicles tab. Once complete, the tag/vehicle attachment is updated across the portal and in the mobile app.   

To detach a tag, select the tracker from the Tags list. Click Detach in the Tag menu. You must make a selection or the button remains grayed out.

Select Confirm in the Vehicle Detachment pop-up window to continue. Otherwise select Cancel to return to the Tags list without making changes. 

Once detached, that Tag and vehicle will no longer be connected for location services and data gathering purposes. Attach a new tag to maintain location and information services for the vehicle.
