To purchase a replacement battery key for your Charge XC bike you will need to contact ABUS Security directly by visiting keys.abus.com. In order for ABUS to send you the correct replacement key you will have needed to register your key with ABUS or to know your key number.
If you did not register your key or do not have your key number you can contact the Charge customer service team by phone at (833) 484-3822 to obtain your key number. If you registered your Charge bike, then we will be able to look up what key you need with your email address, otherwise you will need to provide your bike's serial number.
