Some cars have OnBoard Programming which allows you to create a new car key by following a simple procedure This is not a foolproof method and you still need the vehicle and keys The EEPROM Method EEPROM stands for electrically erasable programmable memory EPROM It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store information It can be programmed to store individual bits of data that are accessed with an address Each byte is either a 1 or one of the numbers When a byte is written to the chip it becomes active and when it is read the bits are decoded to give instructions When writing to an EPROM the source and drain terminals are grounded A high voltage from the control gate tunnels into the silicon oxide and is able to reach the floating gate This causes electrons to flow to the gate and get trapped This causes the gate to alter its content from 0 to 1 When the voltage is cut off 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 changes This is especially crucial for ICs that are powered by battery because a sudden loss of power could cause the chip to reset There are a few ways to reprogram an EEPROM However the majority of them require that the car to be in a specific state It might be necessary for example to disconnect the battery and ECU or to remove the chip and then solder it to an test board The contents of the EEPROM chip could then be read by an EEPROM Reader and copied onto another chip It can be a lengthy process and it can be difficult to get the right data Many people prefer having their cars reprogrammed by experts rather than attempting this at home Find an auto locksmith that is reputable and has advanced tools who knows what they do This will ensure that the key is

programming is also safe as long as the proper procedures are followed In the majority of cases the fob or key will need to be programmed to communicate with the vehicle before it can be used to start the engine Most newer cars have improved transponders inside their electronic keys that require a specially designed programer to function properly A professional can do this fast often within one minute Certain vehicles may require a longer process to complete which can be accomplished by connecting the device to the OBD2 port Some vehicles may require EEPROM programming that can take days
