====== Regain access to a XC3/XD3 device ======
**Note**\\ This document only applies to XC3/XD3 devices running firmware version 10 or newer.
In case you lost access to your XC3/XD3 core device, you can perform a reset. You may have lost access due to:
* Network settings misconfiguration
* Network service misconfiguration
* Lost admin password
**Tip**\\ In case you still have network access to your XC3/XD3 core device and only lost the admin password, follow [[x3:reset-password]].
**Note**\\ The following steps will only reset the admin password and network settings of the core device. Everything else, like Toolbox configuration or stored snapshots, will not be touched.
To reset network settings and admin password on XC3 and XD3 core devices:
==== 1. Locate the FCT key ====
The ''FCT'' key is always located on the rear of the devices.
[{{:x3:52-7520_fct-key.jpeg?700|//Location of the FCT key on 52-7520 XC3 cores//}}]
[{{:x3:52-7550_fct-key.jpeg?700|//Location of the FCT key on 52-7550 XD3 cores//}}]
==== 2. Press and hold the FCT key ====
Press and hold the ''FCT'' key **__for at least 20 seconds__.**
**Important**\\ When pressing ''FCT'' key you should feel only a slight resistance. Do not press the ''FCT'' key too hard to avoid physical damage.
**Tip**\\ To press the ''FCT'' key, a pin tool is required. Alternatively, you can use a straightened paper clip.
==== 3. Setup a new admin user and set network settings ====
After a successful reset, network settings and admin password are reset to factory defaults. To continue, follow [[x3:getting_started]].
