Some cars have OnBoard Programing which allows you to make an entirely new car key by following a simple process This isnt a 100 secure method and you still need the vehicle and keys EEPROM Method The EEPROM is an electrically erasable programmable readonly memory EPROM It is a nonvolatile CMOS chip that stores data in computers as well as other electronic devices It is programmed using individual bytes which are accessible using an address Each byte could be one or zero Once a byte is written to the chip it becomes active The bits are then decoded into instructions when the byte is read When writing to an EPROM the source and drain terminals are grounded A high voltage from the control gate is absorbed into the silicon oxide before it reaches the floating gate This causes electrons to flow to it and then become trapped This causes the gate to change its content from a zero to a 1 If the voltage is removed the gate becomes uncharged and the contents of the EEPROM are erased EEPROMs are commonly used to store calibration coefficients for sensors bootloader configurations and the status of remote keyless system components They can also be used to maintain state between power transitions This is especially important for ICs that are powered by batteries since a sudden loss of power can cause the chip to reset There are several ways to reprogram an EEPROM however the majority of them require that the vehicle be in a particular state at the time For instance it could be necessary to disconnect the ECU from the battery or to take the EEPROM out and then connect it to an test board Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip This process can be timeconsuming and can be difficult to get the right data Most people prefer to have their cars reprogrammed by experts instead of doing it at home Its best to find a trusted auto locksmith who has access to advanced tools and knows what theyre doing This will ensure that the key works and is programmed correctly Its also a good idea to make sure that the locksmith is using genuine parts to avoid issues in the future Onboard Programming A car key programmer

and EEPROM methods may take longer Onboard programming is generally safe as long as the proper procedures and methods are followed In the majority of cases a key fob must be programmed to be able to communicate with the car before it can be used to start the engine The electronic keys that are found in many modern vehicles are equipped with enhanced transponders which require a special programer to work properly A professional can accomplish this quickly often within a minute Connecting the device to an OBD2 port can speed up longerlasting procedures Certain cars may even require EEPROM
