When it comes to the cost of hiring a residential locksmith, the amount you pay will depend on the type of service you require. An emergency locksmith who works 24 hours a day is likely to charge more than a locksmith hired to go out during regular working hours. The cost of changing or re-locking your locks will depend on the complexity of the job and the type of lock you have. Generally, you can expect to pay anywhere from $50 to $200 for a basic lock change.
If you need more complex work done, such as installing a new lock system, you may be looking at a higher cost. It's important to note that tipping a locksmith is not expected or common. Most locksmiths will not accept tips, so it's best to check with them before offering one.
