What Are Car Key Programmers?

Car key programmers are devices that clone a transponder in 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, warning lights for tire pressure, and other functions.

Most of these tools are bidirectional OBD II devices that work with a wide range of vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and controlled "Smart Mode" that helps beginners, while experienced technicians can use the Expert Mode.

Method of EEPROM

EEPROM stands for electrically erasable programmed memory (EPROM). It is a permanent CMOS memory chip that is utilized in computers as well as other electronic devices to store information. It is programmed using individual bytes, which can be accessible via an address. Each byte is either 1 (or a 0). When the byte is written to 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 from the control gate is absorbed into the silicon oxide and is able to reach the floating gate. This allows electrons to flow to it and become trapped. This causes the gate to change its contents from a zero to a 1. When the voltage is cut and program car key 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 the state of the system between power transitions. This is essential for ICs powered by batteries, since a sudden loss of power will cause the chip to reset.

There are several methods to reprogram key fob an EEPROM. However, the majority of them require the car to be in a particular state. For example, it may be necessary to disconnect the ECU from the battery, or remove the EEPROM and solder 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.

It can be a lengthy process, and it is difficult to obtain the correct data. Most people prefer to have their cars reprogrammed by experts instead of doing it at home. It is recommended to hire an auto locksmith that is reliable, has access to sophisticated tools and is aware of what they are doing.
