What Are Car Key Programmers?

Car key programmers are devices that replicate a transponder into the memory of a car. They are useful to replace keys that are stolen or lost. They can also be used to reset the oil service light, tire pressure warning light and many other functions.

EEPROM Method

EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a nonvolatile CMOS memory chip that is utilized in computers as well as other electronic devices to store data. It can be programmed with individual bytes that are accessible via an address. Each byte can be either one or zero. When a byte is written to the chip, it is activated and, when it is read, the bits are decoded to give instructions.

When writing into an EPROM, both the source and drain are grounded. A high voltage that is channeled from the control gate passes through the silicon oxide to the floating gate and causes electrons to flow through it and get trapped. This causes the gate to change its contents from a 0 into a 1. If the voltage is removed the gate is uncharged and the contents of the EEPROM are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components. They can also be used to keep track of state between power-related transitions. This is crucial for ICs powered by batteries as a sudden loss of power will cause the chip to reset.

There are several methods to reprogram an EEPROM. However, the majority of them require the vehicle to be in a certain state. It may be necessary, for instance, to disconnect the battery and ECU or to remove the chip and place it on a test board. Then the contents of the EEPROM can be read by an EEPROM reader and copied to another chip.
