What Are Car Key Programmers?

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

These devices are usually bidirectional OBD II devices, which are compatible with a variety of vehicles. Some, like the Autel MaxiIM IM608S II, provide an automated and supervised Smart Mode that helps beginners while experienced technicians can use Expert Mode.

The Basics

The procedure of programming a car key lets you to reprogram a blank chip in a replacement key, so that it matches the vehicle's settings. This allows the key to communicate and start the vehicle. Although it is possible to accomplish this with a standard mechanical car key, modern cars require a device called a "car key programmer." These are usually standalone devices but are sometimes integrated into more sophisticated scan tools.

There are several factors to consider when selecting the right car key programming device. First, consider your budget. The cost of car key programmers can differ, so it's crucial to select one that is within your budget. Before you purchase do some research on various models and read user reviews.

EEPROM Method

The EEPROM is an electrically erasable read-only memory that is programmable (EPROM). It is a nonvolatile CMOS chip that is used to store data in computers as well as other electronic devices. It can be programmed to store individual bits of data that can be accessed using an address. Each byte may be 1 or 0. When a byte has been written to the chip, it becomes active. The bits are encoded into instructions when the byte is read.

When writing to an EPROM the drain and source are grounded. A high voltage that is channeled from the control gate tunnels through the silicon oxide and into the floating gate and causes electrons to flow through it and get trapped. This causes the gate to alter its content from 0 to 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 preserve state between power transitions. This is especially crucial for ICs that are powered by batteries, since a sudden loss of power can cause the chip to reset.

There are a few ways to reprogram an EEPROM. However, the majority of them require the car to be in a certain state. It may be necessary, for example to disconnect the ECU and battery or to remove the chip and then solder it to an test board. Then, the contents of the EEPROM can be read by an EEPROM reader and copied to a different chip.
