1. A method for operating a deadbolt system, the method comprising:
extending a deadbolt from a retracted position to an extended position at a first time;
recording a first resistance signature that is at least partially indicative of a performance of a deadbolt;
extending the deadbolt from the retracted position to the extended position at a second time;
recording a second resistance signature that is at least partially indicative of the performance of the deadbolt;
extending the deadbolt from the retracted position to the extended position at a third time and recording a third resistance signature at least partially indicative of the performance of the deadbolt;
averaging the second resistance signature and the third resistance signature to create an average signature; and
comparing the first resistance signature to the average signature.
