As there is no instructions for the roadlock, you don't have to take the bracket off the caliper to remove the barrel .I did here but just in case as its not obvious for the non mechanically minded
To remove the lock
barrel (lock cylinder):
1. Turn the key to the fully unlocked position.
2. Insert a small allen key into the crosshole on the lock body, and press
it into the deadbolt, which will force the deadbolt to push inside the
lock cylinder.
3. Pull on the key, and the entire lock cylinder should slide out of the lock
body.
4. Clean and replace.
