Abstract
A rekeyable lock cylinder and a padlock with a rekeyable lock cylinder includes a cylindrical core formed to receive a key and an outer casing formed around the core. The cylinder core may be provided with one or more reconfiguration channels. Pins and springs mounted in openings formed in a spring holder connected to the casing can be removed through the one or more reconfiguration channels when the reconfiguration channels in the core align with assembly openings in the casing and the pin openings in the spring holder, thereby allowing the adaptation of the number of pins mounted in the lock cylinder to the number of cuts provided in the key.
