Question 1

Which device do automotive locksmiths use to read and write EEPROM data from a vehicle's immobilizer control unit?

Accepted Answer

EEPROM programmer/reader

Answer

An EEPROM programmer (such as the Orange5 or similar) is used to physically read data from and write data to the EEPROM chip in an immobilizer control unit, enabling key programming when OBD methods fail.

Question 2

A transponder key tester is used to verify:

Accepted Answer

Whether a transponder chip inside a key is functioning and transmitting the correct signal

Answer

A transponder tester checks that the chip inside the key is active, reads the chip type, and confirms it is transmitting an appropriate signal before programming begins.

Question 3

What is the primary difference between an OBD-II key programmer and a standalone key programmer?

Accepted Answer

OBD-II programmers connect via the vehicle's diagnostic port, while standalone units may work without a working key or OBD access

Answer

OBD-II programmers connect through the diagnostic port and often require at least one working key, while standalone programmers can work via direct ECU connection or other bypass methods when no working key exists.

Question 4

A 'token' in the context of key programming tools (e.g., Autel, Advanced Diagnostics) refers to:

Accepted Answer

A unit of credit consumed when programming a key on supported vehicles

Answer

Tokens are credits within key programming software platforms that are consumed each time a locksmith programs a key on a supported vehicle, representing the cost of accessing manufacturer-level programming data.

Question 5

Which tool is commonly used to clone a fixed-code (non-rolling-code) transponder key without programming access to the vehicle?

Accepted Answer

Transponder cloner (e.g., CN900 or similar)

Answer

A transponder cloner reads the data from a working transponder key and writes an exact copy to a compatible blank chip, allowing duplication of fixed-code transponders without vehicle access.
