✍️ Sample CAL Questions & Answers
1. When selecting a key blank for duplication, which of the following is the MOST important initial factor for a standard (non-high-security) key?
The most critical factor in selecting a key blank is ensuring the keyway profile (the shape of the blade and its grooves) and the overall length match the original key and the vehicle's locks. An incorrect profile will not even enter the lock cylinder, making any cutting or programming attempts futile.
2. What is the primary function of a vehicle ignition system?
The ignition system provides the electrical spark needed to start the engine and keep it running efficiently.
3. Which of the following best describes a 'passive entry' system on modern vehicles?
Passive entry systems use low-frequency signals to detect an authorized fob within range and automatically unlock the door when the handle is touched, requiring no button press from the driver.
4. What should be done before replacing an ignition switch?
Disconnecting the battery prevents electrical shocks and damage when working on the ignition system.
5. Under the ALOA code of ethics, which practice is explicitly prohibited for automotive locksmiths?
The ALOA code of ethics prohibits sharing security bypass knowledge with unvetted individuals who could misuse it for criminal purposes.
6. When servicing a trunk latch that will not release via the interior handle, what component should be checked first?
A binding, kinked, or disconnected release cable or actuator rod is the most common mechanical cause of trunk latch failure and should be inspected before checking electronic components.
