What Are Car Key Programmers? Car key programmers are devices that clone a transponder in the memory of a vehicle. These can be used to replace keys that have been stolen or lost. They can be used to reset the oil service light as well as warning lights for tire pressure, and other functions.

Method of EEPROM EEPROM is the abbreviation for electrically eraseable programmable memory (EPROM). It is a non-volatile CMOS memory chip that is used in computers as well as other electronic devices to store information. It is programmed using individual bytes, which can be accessed using an address. Each byte can be either a 1 or a 0. If a byte has been written to the chip it becomes active. The bits are decoded into instructions when the byte is read. When writing into an EPROM the source and drain are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This causes electrons to flow in to it and then become trapped. The gate's contents to change from a zero to a 1. If the voltage is removed the gate ceases to be charged and the contents of the EEPROM are erased. EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless systems components. They can also be used to maintain the state of the system between power transitions. This is essential for ICs powered by batteries because a sudden loss in power will cause the chip to reset. There are several methods to reprogram an EEPROM. However, most of them require the car to be in a particular state. For instance, it might be necessary to disconnect the ECU from the battery or remove the EEPROM and then connect it to a test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and copied to another chip. It is a lengthy process, and it is difficult to obtain the correct information. Most people prefer to have their vehicles reprogrammed by professionals rather than trying this at home.
