What Are Car Key Programmers?

Car key programmers are devices that clone a transponder in the memory of a car. These are useful for replacing keys that have been stolen or lost. They can also be used to reset oil service light and warning lights for tire pressure and other lights.

Method of EEPROM

The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and some other electronic devices to store data. It is programmed using individual bytes, which are accessible via an address. Each byte may be 1 or 0. When the byte is written to the chip, it is activated and, when it is read, the bits are decoded into instructions.

When writing into an EPROM, both the source and drain are grounded. A high voltage channeled from the control gate travels through the silicon oxide and into the floating gate which causes electrons to flow through it and then become trapped. The gate's contents to change from a 0 a 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs are typically 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 especially crucial for ICs that are powered by batteries, since 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 particular state. It might be necessary, for instance, to disconnect the battery and ECU or remove the chip and place it on an test board. The contents of the EEPROM chip can be read by an EEPROM Reader and copied to another chip.

Most newer cars have improved transponders inside their electronic keys that require a specific programer to function correctly. A professional can do this quickly, often in as little as one minute.

Connecting the device to an OBD2 port can aid in the process of. Some cars might even need EEPROM programming procedures that can take days.
