Usually the locksmith will be able to rekey the locks in his service van. Most of the locks will take about 10 minutes to rekey and the locksmith can charge you anywhere from $10 to $30 for each lock rekeyed. Most locksmiths will include a few free keys. The locksmith will also charge you for the travel time to you.
Rekeying a lock is replacing the old lock pins with new lock pins. Locks are usually re keyed to build master-key systems, make a set of locks share a common key, or to eliminate compromised keys. Sometimes worn pins are replaced with new pins if the old pins become too short to reach the shear-line. The shear-line is the thin line shared by the plug and it's cylindrical housing.
