Abstract
A locking device for securing a bicycle or the like to a post or other fixture. The locking device features a replaceable lock cylinder, which in turn allows for both replacing merely the lock cylinder when the keys get lost and also allows for conforming the lock cylinder of the device to an identical lock cylinder used in the owner's home so that one key, preferably a flat key, services both the device and the home. The lock cylinder cannot, however, be removed when the device is locked and in use. The key, on the other hand, can only be removed when the device is locked.
