What Are Car Key Programmers?

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

The Basics

The procedure of programming a car key allows you to reprogram an uncoded chip in a replacement key so that it conforms to the vehicle's settings. This allows the key to communicate with the vehicle, and ensures that the key will be capable of starting and running the engine. It is possible to do this with a car key that is mechanical. However modern vehicles require an instrument known as a "car-key programmer". These devices are typically standalone, but can sometimes be integrated into scan tools that are more complex.

There are a few aspects to take into consideration when selecting the best car key programmer. First, consider your budget. The cost of car key programmers can vary, so it's important to choose one that fits within your budget. Before making a purchase make sure you research different models and read customer reviews.

Method of EEPROM

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a non-volatile CMOS memory chip that is utilized in computers and other electronic devices to store data. It is programmed to store individual bytes that are accessed with an address. Each byte can be either a 1 or a 0. When the byte is written to the chip, it becomes active and when it is read the bits are decoded to give instructions.

When writing to an EPROM the source and drain terminals are grounded. A high voltage from the control gate is absorbed through the silicon oxide and reaches the floating gate. This causes electrons to flow in to it and then become trapped. This causes the gate to change its contents from a 0 into a 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents 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 are also used to keep track of state between power transitions. This is especially important 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 that the car be in a certain state at the time. For instance, it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and connect it to a test board. Then, the contents of the EEPROM can be read with an EEPROM reader and copied to a different chip.

It is a lengthy process, and it can be difficult to get the right information. The majority of people prefer having their cars reprogrammed by experts rather than attempting this at home.

In most instances, the key or fob will require programming to communicate with the vehicle before it can be used to start the engine. The electronic keys in most modern cars come with upgraded transponders that require a specific programer to function correctly. A professional can complete this fast, often in less than one minute.

Some cars may need a longer process to complete, which can be accomplished by connecting the device to the OBD2 port. Some cars might even need EEPROM programming procedures that can take days.
