How Does Locksmith Make Keys?

Key duplication, key decoding, and rekeying are some of the everyday jobs of a locksmith. However, people often wonder how locksmiths manage to duplicate a key for different locking mechanisms. Locksmiths have the mechanical skills and years of experience that help them rekey a home or design a new key for a specific lock with lost keys.

Whether you have lost home keys or got yourself locked out of a car, a locksmith is the first person you will dial. Only a licensed and professional locksmith has the potential to arrive at your place, check your lock mechanism, and create new keys for your home. But the question is, how does a locksmith make keys? Let’s find out.

Designing New Car Keys with Scoping 

Even though the keyless ignition system has become the number one choice of car manufacturers and buyers, some truck and vehicle models still have those traditional locking mechanisms for lost keys. 

Sometimes, people get their remote car keys locked inside their car, and they end up being locked out of the vehicle. In such cases, a locksmith makes car keys to help the driver access the vehicle without spending a fortune on buying a new transponder key.

Scoping is the process of inserting a small instrument into the vehicle’s lock. The scope inserted into the car’s lock system reads the lock mechanism and helps locksmiths design the matching car key that could safely open the car doors.


Most lock manufacturers provide car buyers with a factor key code that a locksmith can use for duplicating the car keys in case of an emergency. This factor code consists of a series of letters and characters. Only a licensed and qualified locksmith can read these characters and use this information to cut new car keys that match the lock structure.

Cutting a new key using the factor codes or visual critical assessment is known as decoding. The process works for both lost keys and worn-out keys. The factor code is available primarily on a key or lock cylinder.

Lock Disassembly 

Locksmiths can disassemble the lock cylinder to assess the lock pins’ height, length, and alignment. Lock disassembly is mainly considered the last resort since the procedure is time-consuming. A locksmith may need to spend hours disassembling the lock and evaluating its structure to design a brand-new key.

Lock disassembly isn’t expected. Locksmiths only prefer this process when replacing the lock seems challenging, such as the locks of the heritage home. Lock disassembly can also be performed on car locks.

Bump Keys

Bump keys are a unique form of keys designed to fit into residential doors, bathroom doors, and other mechanical locks. After inserting the key into an automatic door, the locksmith twists the key slightly to open the door.

These were the few lock key designing techniques. If you misplace your car key or lose keys to your home, contact your nearest locksmith agency and design the duplicate keys. Good Luck!
