On-Board programming Modern key fobs are more than unlock the rear hatch and allow you to start your car. Transponders connect to the vehicle via an antenna and transmit data such as an ID number or VIN.

Some vehicles have an easy procedure, whereas others need special software and key programming tools. If you're working with an automobile with onboard programming, the owner's guide or Internet search for “onboard programming steps for X vehicle” will give you the information you need. In certain cases, the key will need to be cloned, which means that the new key has to have the same immobilizer codes as the one that is currently. This is done by using an instrument for programming keys that will burn the code onto the key. Some vehicles require the transponder to be completely reprogrammed. This is possible with the J2534 connection however, it usually requires the removal of the module.

EEPROM Programming EEPROM is a non-volatile memory that will not lose data even when the power is turned off.
