What Are Car Key Programmers?

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

Most of these tools are bidirectional OBD II devices that work with a wide range of vehicles. Some tools, such as the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps novice technicians, while more experienced technicians can benefit from the Expert Mode.

These are usually standalone devices, but they can also be integrated into more complex scanners.

When it comes to choosing the best car key programmer for your requirements, there are a few key factors that you need to be aware of. First, consider your budget. The cost of car key programming devices can vary, which is why it's essential to find one within your budget. Before purchasing, do some research on various models and read user reviews.

Method of EEPROM

EEPROM is an acronym for electrically erasable memory that is programmable (EPROM). It is a permanent CMOS memory chip used in computers as well as other electronic devices to store information. It can be programmed with individual bytes, which can be accessible using an address. Each byte is either 1 (or one of the numbers). When a byte has been written to the chip it becomes active. The bits are then converted into instructions when the byte is read.

When writing to an EPROM the drain and source terminals are grounded. A high voltage from the control gate passes through the silicon oxide and is able to reach the floating gate. This causes electrons to flow in to the gate and get trapped. The gate's contents to change from a zero to 1. When the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless system components. They can also be used to maintain status between power changes. This is essential for ICs powered by batteries, since a sudden loss of power can cause the chip to reset.

There are several methods to reprogram an EEPROM, but most of them require that the vehicle be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery, or remove the EEPROM and then connect it to an test board. The contents of the EEPROM chip could then be read by an EEPROM Reader and then copied onto another chip.
