ABSTRACT:
Disclosed is a keylock having a key settable lever tumbler which can be bent, by use of an operating key, from an initial neutral configuration to set it to the operating key, and which by use of a change key can be restored to its initial configuration and then reset to other operating keys. The tumbler can be rebent and reset to different keys a substantial number of times. The accuracy of the rebending is assured by imparting an overbend which accommodates the spring back that accompanies the rebending.
