What is a 'key section' in key blank terminology?
Answer: The cross-sectional profile of the key blade that must match the keyway
The key section describes the cross-sectional shape of the blade, which must match the corresponding keyway's warding to allow the key to enter and turn.
When using an electronic code-cutting machine, a 'zero-out' or calibration procedure is performed to:
Answer: Establish a precise reference position so all subsequent cuts are accurately located
Zeroing out calibrates the machine's position sensors to a known reference, ensuring all cut depths and spacings are accurate.
A locksmith is originating a key and finds the code prefix indicates 'FO' on a Ford vehicle. This prefix most likely identifies:
Answer: The key blank series and keyway profile applicable to that vehicle line
Code prefixes like 'FO' identify the key blank series and keyway associated with a specific vehicle manufacturer and line, directing the locksmith to the correct blank and code section.
The term 'key-in-knob' (KIK) cylinder refers to a cylinder designed to:
Answer: Be installed in a cylindrical knob lock with a specific tailpiece configuration
A KIK cylinder is specifically dimensioned and configured to fit inside cylindrical (knob or lever) lock hardware.
During key origination, a locksmith finds that cut #3 on the code calls for a depth of '7' but the key blank's maximum cut depth only goes to '6'. This indicates:
Answer: The wrong key blank has been selected for this code system
If the required depth exceeds the blank's range, the wrong blank was selected; each key system has a defined blank that accommodates its full depth range.
What distinguishes 'laser-cut' (also called side-milled or internal cut) keys from standard keys?
Answer: Their cuts are made on the side of the blade rather than the top edge, requiring specialized equipment to duplicate
Laser-cut keys feature cuts milled into the side or face of the blade rather than along the top edge, and require a specialized sidewinder cutting machine to originate or duplicate.
A 'do-not-duplicate' (DND) stamp on a key:
Answer: Is a manufacturer's or owner's request that carries no enforceable legal restriction in most US jurisdictions
In most US states, a DND stamp is a request or policy marker only; it carries no enforceable legal prohibition on duplication unless backed by a restricted keyway patent.
