The key to a bicycle alarm lock usually has a special design that cannot be easily replicated. Users should keep their keys properly to avoid loss or theft. To ensure the normal operation of the alarm lock, users should regularly check the battery level and lock body status. If there are any abnormalities, the battery should be replaced or the lock body should be repaired in a timely manner. Although bicycle alarm locks can provide some security, users should still park their vehicles reasonably and avoid parking them in remote or unattended areas.
