What Are Car Key Programmers?

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

These are typically bidirectional OBD II devices, which work with a variety of vehicles. Some, like the Autel MaxiIM IM608S II, have an automated and guided Smart Mode that aids novices, while experienced technicians can use Expert Mode.

The Basics

The process of programming a car keys allows you to recode a blank chip in a replacement key, so that it matches the car’s settings. This allows the key to communicate with and start the vehicle.

The EEPROM Method

EEPROM stands for electrically erasable programmable memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store data. It can be programmed with individual bytes that are accessed using an address. Each byte may be 1 or 0. When a byte has been recorded to the chip it becomes active. The bits are converted into instructions when the byte is read.

When writing into an EPROM, both the drain and source are grounded. A high voltage channeled from the control gate travels through the silicon oxide to the floating gate and causes electrons to flow through it and then become trapped. The gate’s contents to change from a zero to a 1. When the voltage is removed the gate is uncharged, and the contents of the EEPROM are erased.

EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They are also used to keep track of state between power changes. This is especially crucial for ICs that are powered by batteries since a sudden loss of power could cause the chip to reset.

There are a few methods to reprogram an EEPROM however, the majority of them require that the vehicle be in a specific condition at the time of. It could be necessary, for example to disconnect the battery and ECU or to take the chip off and solder it onto a test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and copied onto another chip.
