Using your Foldylock Forever 90 is easy. First, unfold it from the mounting case. Wrap it around the part of your bike or e - scooter you want to secure and insert the key into the lock cylinder to lock it. When you're done, just unlock it and fold it back into the case. Here are some things to keep in mind. Don't expose the lock to extreme temperatures or harsh chemicals. Avoid dropping it or hitting it hard as this might damage the internal mechanism. For maintenance, you can clean the lock with a dry cloth regularly. If it seems a bit stiff, you can use a small amount of graphite powder in the keyhole. This will keep the lock working smoothly and help it last a long time.
