Common problems and their reasons

Most problems can be solved quite easily. Please check first at the according product page for known issues and product specific troubleshooting. The following table gives you an overview over common problems as well as how to fix them:

Observed behavior Reason How to fix Implications
The lock does not react at all. The battery is empty. Replace the battery. After replacing the battery, it may be necessary to set the time on the lock again.
The lock or mobile device signals that there's no valid token. The time on the lock is wrong. Check the time using the 'gtim' command. That token must start before 1/1/2016 00:00 UTC. If the time is inaccurate, set the time using the 'time' command. Please bear in mind that setting the wrong time is a security threat. Thus, this should only be done by authorized persons.
The token is expired. Create a new token.
The token is not valid yet. If you are sure that the token should be valid, the time on the lock may be inaccurate. See above for setting the time.
The token was revoked. Create a new token.
The mobile device cannot find the lock. You are not in front of the lock. Please make sure you selected the right lock and you are in front of it.
The battery is empty. See above for replacing the battery.
The Bluetooth module of your smartphone has issues. Put your smartphone into flight mode, wait a few seconds, turn it on again and try again.
If that does not help, try to reboot your smartphone and try again.
The BlueID Token Card is not working. The time on the lock is wrong. See above 'The time on the lock is wrong'
The BlueID Token Card is broken Replace the BlueID Token Card through an other
The BlueID Token Card has no valid token for that lock Contact your BlueID Token Card issuer and check or rewrite the card
The command 'tokn' does not work. Office mode is enabled. Disable the office mode using the 'diof' command.

If supported by the lock, please try to access it with a different interface, e.g. when you have problems using Bluetooth, try to use it with NFC with a BlueID Token Card and vice versa.

If you cannot access a lock via Bluetooth, please try a different phone or use a BLE scanning app to see if the lock is even visible. Please note that the Secured Object ID is not the local name of a Secured Object! You can retrieve the proper local name using the Operator API.

Details from the Operator API

With the BlueID Operator API, you can get much information about your devices and tokens. If possible/applicable, please query the Operator API to provide information about:

  • the Secured Object

  • the Mobile Device

  • the BlueID Token/Ticket that was used

Document the behavior of the lock

If the lock is not completely dead (e.g. due to an empty battery), it responds with acoustic and visual feedback. The easiest and less error-prone way to provide information about these sequences is to make a video recording of the lock when the problem arises.
