Method of EEPROM EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a permanent CMOS chip that stores data in computers as well as other electronic devices. It can be programmed to store individual bits of data which can be accessed via an address. Each byte could be a 1 or a 0. When the byte is written on the chip it becomes active, and when it is read, the bits are decoded into instructions. When writing to an EPROM, the source and drain terminals are grounded. A high voltage channeled from the control gate travels through the silicon oxide to the floating gate which causes electrons to flow through it and become trapped. This causes the gate to change its content from 0 to 1. When the voltage is removed, the gate becomes uncharged, and the contents of the EEPROM are erased. EEPROMs are often used to store calibration coefficients for sensors, bootloader configurations and the status of remote keyless system components. They can also be used to preserve status between power changes. This is important for ICs powered by batteries because a sudden loss in power can cause the chip to reset. There are a variety of methods to reprogram an EEPROM however, the majority of them require that the vehicle be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery, or to remove the EEPROM and then connect it to the test board. The contents of the EEPROM chip could then be read with an EEPROM Reader and then copied onto another chip. This can be a lengthy process and can be difficult to find the correct data. Many people prefer having their vehicles reprogrammed by professionals instead of doing it at home. It is best to locate an auto locksmith who is reputable, has access to sophisticated tools and understands what they're doing. This will ensure that the key will work and is programmed correctly. To avoid any future issues it's recommended for the locksmith to use genuine parts. Onboard Programming A car key programmer is a handheld device that is used to programme new remote keys or fobs.

There are three kinds of car key programming devices including onboard, EEPROM and OBD2. Each has distinct advantages and drawbacks. Onboard programming is generally the fastest, whereas OBD2 and EEPROM methods may take longer. Onboard programming is generally secure as long as proper procedures and protocols are adhered to. In the majority of cases the key or fob must 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 specific programer to function properly. A professional can perform this task efficiently, often in less than a minute. Certain vehicles may require an extended procedure that can be completed by connecting the device to the OBD2 port. Certain vehicles may require EEPROM programming, which can take a number of days.
