What Are Car Key Programmers?

Car key programmers are devices that can duplicate a transponder within the memory of a vehicle. These can be used to replace keys that have been stolen or lost. They can also be used to reset the oil service light as well as warning lights for tire pressure and many other functions.

These tools are mostly bidirectional OBD II devices, which can be used with a variety vehicles. Some tools, like the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps novice technicians, while more experienced technicians can utilize the Expert Mode.


The Basics

Car key programming is a method that lets you recode the blank chip inside your replacement key to ensure it matches the current settings of your vehicle. This allows the key to communicate with the vehicle, and also ensures that the key is able to start and run the engine. While it is possible to accomplish this with a standard mechanical car key, modern vehicles require a device known as a "car key programmer." These are typically standalone devices, but they can also be integrated into more sophisticated scanners.

There are a few aspects to consider when selecting the best car key programmer. First, consider your budget. Car key programs vary in price, so it's crucial to choose one that is within your budget.

EEPROM Method

The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a permanent CMOS chip which is used to store data in computers as well as other electronic devices. It can be programmed using individual bytes, which are accessible via an address. Each byte can be either a 1 (or a 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 through the control gate passes through the silicon oxide to the floating gate which causes electrons to flow through it and get trapped. This causes the gate to change its content from a zero to a 1. When the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs are often 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 status between power changes. This is particularly important for ICs that are powered by batteries, since a sudden power loss could cause the chip to reset.

There are a few ways to reprogram an EEPROM. However, most of them require that the car to be in a certain state. For example, it may be necessary to disconnect the ECU from the battery, or to take the EEPROM out and then connect it to a test board. Then the contents of the EEPROM can be read with an EEPROM reader and transferred to a different chip.

The majority of people prefer having their vehicles reprogrammed by professionals rather than trying this at home.

A professional can complete this task efficiently, often in less than an hour.

Connecting the device to an OBD2 port can aid in longer-lasting procedures. Certain vehicles may require EEPROM programming, which could take several days.
