Frequently Asked Questions

Locksmiths can fix their pricing in two different ways:
– The cost of a service call or trip charge includes the travel to the location and the task required.
– A flat rate for different kinds of work done.
Whatever the type of cost, a professional locksmith will give you a quote before coming to your location. On average, locksmiths in St. Louis will charge anywhere between $75 and $100 for a lockout.

Yes. Most locksmiths are able to make a safe key. In some cases, this may take longer than other types of keys, but it is possible. Professional locksmiths will also give you information about which keys can easily be duplicated and which ones may not be very easy to duplicate.

Locksmiths are experts at breaking old locks and creating new locks and keys for any home or vehicle. As such, they will be able to unlock a house and get in if you have lost the key. They will have all the essential tools required to unlock any door and open it. They will also be able to make a copy of your key for you if you lose the original.

Replacing a lock is self-explanatory: the locksmith changes your old lock with a new one. Rekeying, on the other hand, is a bit different – the locksmith replaces the working key of the lock but keeps the same lock. The lock is, however, taken apart and some parts inside are replaced (the “key pins” or “tumblers”).

In most cases, a locksmith can rekey your locks even if you've lost or misplaced the original key. He/she can either shim or pick the lock in order to unlock the door. When rekeying a lock cylinder, the locksmith will have an easier time removing the lock cylinder after bringing the lock to the “unlock” position.
