CAL - Certified Automotive Locksmith Key Generation and Duplication Questions and Answers

Question 1

A customer has lost all keys to their 2018 Honda Accord with a push-to-start ignition. Which of the following methods is the MOST appropriate first step for an automotive locksmith to generate a new key?

Accepted Answer

Obtain the vehicle's key code using the VIN and cut a new key, then program it via the OBD-II port.

Answer

In an 'All Keys Lost' (AKL) situation for a modern vehicle like a 2018 Honda, the standard and most efficient procedure is to first obtain the key code from the vehicle manufacturer or a licensed broker using the Vehicle Identification Number (VIN). This code provides the specific cuts for the physical key blade. Once the key is cut, the locksmith programs the new key's transponder to the vehicle's immobilizer system using a diagnostic tool connected to the OBD-II port.

Question 2

When duplicating a transponder key, what is the primary difference between 'cloning' and 'programming' a new key?

Accepted Answer

Programming creates a new, unique identity for the key in the vehicle's computer, while cloning creates an exact electronic copy of an existing key.

Answer

Key cloning reads the data from an existing transponder chip and writes it to a new chip, creating an identical twin of the original key. The vehicle's computer sees both keys as the same. Key programming, on the other hand, involves introducing a new, unique transponder key to the vehicle's immobilizer system. The car's computer registers this new key as a distinct, additional key authorized to start the vehicle.

Question 3

Which of the following is a critical prerequisite before cutting and programming a new key for a customer in an 'All Keys Lost' situation?

Accepted Answer

Verifying the customer's proof of ownership of the vehicle.

Answer

Before generating a new key for a vehicle, especially when no original key is present, it is an essential security and legal practice to verify that the customer is the legitimate owner. This is typically done by checking their photo ID against the vehicle's registration or title. This step prevents the creation of unauthorized keys and protects both the vehicle owner and the locksmith.

Question 4

A locksmith needs to generate a key for a high-security vehicle where OBD programming is not possible due to a locked immobilizer system. What is the most likely advanced procedure to use?

Accepted Answer

Performing EEPROM work to directly read and write key data on the immobilizer's memory chip.

Answer

EEPROM (Electrically Erasable Programmable Read-Only Memory) work is an advanced technique used when standard OBD programming fails or is not supported. It involves physically removing the vehicle's immobilizer module or ECU, locating the memory chip that stores key data, and using a specialized programmer to read the data. This data can then be used to generate a new transponder chip for the key.

Question 5

When selecting a key blank for duplication, which of the following is the MOST important initial factor for a standard (non-high-security) key?

Accepted Answer

The correct keyway profile and blade length.

Answer

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.
