Todays automotive locksmith encounters a variety of vehicle security issues. A common customer problem is lost keys, a failed immobilizer or defective ECU. Regardless of the vehicle, in order to solve the problem, the automotive locksmith must be able to retrieve key security information or reprogram the memory chip inside the module itself (immobilizer or ECU). The memory part which stores the key data sequence is called an EEPROM. EEPROM stands for "E"lectrically "E"rasable "P"rogrammable "R"ead "O"nly "M"emory. This is a memory technology which has a unique characteristic; it does not loose its data when power is removed. The work of an automotive locksmith usually involves one of two procedures; REFLASHING or EEPROM WORK.
REFLASHING - Reflashing is a proven technique where a vehicle immobilizer is programmed with a special file which restores the EEPROM to the original factory values (same condition as a new immobilizer). After reflashing and reinstallation, the vehicle will be in "learn mode" and able to accept new keys.
Reflashing is commonly used on Toyota, Lexus, Honda and Acura vehicles.
EEPROM WORK -
EEPROM work is a term used by automotive locksmiths to describe working with the data stored in the eeprom itself to create or add keys. Unlike reflashing, this technique applies to a wide variety of vehicles. EEPROM work requires a tool (locksmith kit) which is capable of reading data from an eeprom and saving it to a file. The file is then passed to a "Transponder Programmer" the function of which is to use the eeprom data file to make the key. The key is guaranteed to start the car since it was created directly from the original eeprom data. EEPROM work is a different procedure, but once mastered, is faster and more profitable since it takes much less time to provide a replacement key for the customer.
