What Are Car Key Programmers?

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

Most of these tools are bidirectional OBD II devices that work with a broad range of vehicles. Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode that aids novices, while more experienced technicians can utilize Expert Mode.

The Basics

The process of programming a car key allows you to recode an uncoded chip in a replacement key to ensure that it is compatible with the car's settings. This allows the key to communicate with the vehicle and ensures the key is able to start and run the engine. It is possible to do so with a car key that is mechanical. However, modern vehicles need a device called a "car-key programmer". These devices are typically standalone, but can sometimes be integrated into more sophisticated scan tools.

When it comes down to choosing the best car key programmer for your requirements, there are a few essential aspects that you must be aware of. First, consider your budget. Car key programmers range in price, so it is essential to find one that is within your budget. Additionally, make sure to study various models and read reviews before making the purchase.

EEPROM Method

The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a permanent CMOS chip which is used to store information in computers and other electronic devices. It can be programmed to store individual bytes which can be accessed via an address. Each byte can be either a 1 or a 0. When a byte has been written to the chip, it is activated. The bits are then converted into instructions when the byte is read.

When writing data into an EPROM the drain and source are grounded. A high voltage from the control gate passes through 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 alter its content from a 0 into a 1. When the voltage is cut off the gate is uncharged and the contents of the EEPROM are erased.

EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless systems components. They are also used to keep track of state between power changes. This is particularly important for ICs that are powered by batteries, because a sudden loss of power could cause the chip to reset.

There are a couple of methods to reprogram an EEPROM. However, most of them require that the car to be in a particular state. For instance, it could be necessary to disconnect the ECU from the battery or to take the EEPROM out and connect it to an test board. The contents of the EEPROM chip can then be read using an EEPROM Reader and then copied onto another chip.

This process can be lengthy and it may be difficult to obtain the right data. Many people prefer having their vehicles reprogrammed by professionals instead of doing it at home. It is best to locate a trusted auto locksmith who has access to sophisticated tools and is aware of what they are doing.
