What Are Car Key Programmers?

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

The majority of these devices are bidirectional OBD II devices that work with a broad range of vehicles. Some, like the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while experienced technicians can use Expert Mode.

The Basics

The process of programming a car key allows you to reprogram a blank chip for a replacement key to ensure that it is compatible with the settings of your vehicle. This enables the key to communicate with the vehicle, and ensures the key is capable of running and starting the engine. It is possible to do so with a car key that is mechanical.

The EEPROM Method

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

When writing to an EPROM, both the drain and source are grounded. A high voltage from the control gate passes through the silicon oxide and reaches the floating gate. This causes electrons to flow to the gate and get trapped. This causes the gate to change its contents from a 0 into a 1. When the voltage is cut off, the gate becomes uncharged, and the contents of the EEPROM are erased.

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

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

This process can be lengthy and can be difficult to get the correct data. The majority of people prefer having their vehicles reprogrammed by professionals rather than attempting this at home. It is best to locate a trusted auto locksmith who has access to advanced tools and is aware of what they are doing. This will ensure that the key is working and is properly programmed.
