  • Some phones require the screen to be unlocked

Troubleshooting

  • Yellow light - forgot your PIN?

    When you created your digital card, you also set a personal PIN code. Follow this guide to change it: Change PIN code

  • Red light - no access?

    Red light can mean you don't have access to this door, that access is not active at the time of day you're trying to enter (e.g. outside 0800-1600), that the reader isn't making proper contact with the card, or that you entered the wrong PIN.

    • Check if your phone works on other doors you know you have access to

    • If it concerns a specific door you believe you should have access to then contact your company administrator

    • Check if a colleague with the same access group can enter the door
