Here are the activation steps for a BIXI key. The activation must be completed before you can rent a BIXI using your key.
Log in to your BIXI space through the website and scroll down to the Preferences section.
Under Preferences, you will find Add your bike key. Press on Add and insert the number of the key you received by mail. You will find the number written under the barcode. Once you have entered the number, press on Add now.
Your profile will now reflect that your key was successfully associated to your account!
