What Are Car Key Programmers? Car key programmers are devices that replicate a transponder into the memory of a vehicle. These are useful for replacing keys that have been stolen or lost. They can also be used to reset the oil service light, tire pressure warning light and other functions. Most of these devices are bidirectional OBD II devices that work with a wide range of vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and controlled “Smart Mode” that helps novices, while skilled technicians can benefit from the Expert Mode. The Basics The process of programming a car key allows you to change the code of an uncoded chip for a replacement key so that it conforms to the car's settings. This allows the key to communicate with the vehicle, and ensures the key is capable of running and starting the engine. While it is possible to do this with a standard mechanical car key, modern vehicles require a device known as a “car key programmer.” These are usually standalone devices but are sometimes integrated into more complex scan tools. When it comes to choosing the best car key programmer for your needs, there are few important aspects you must keep in mind. First, consider your budget.

EEPROM Method EEPROM is the abbreviation for electrically eraseable programmable memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store data. It is programmed to store individual bits of data that are accessed with an address. Each byte is either a 1 (or an 0). If a byte has been written to the chip it is activated. The bits are encoded into instructions when the byte is read. When writing into an EPROM the drain and source are grounded. A high voltage channeled through the control gate passes through the silicon oxide to the floating gate and causes electrons to flow through it and get trapped. This causes the gate to alter its content from 0 to 1. When the voltage is removed the gate is uncharged and the contents of the EEPROM are erased. EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to maintain state between power changes. This is especially crucial for ICs that are powered by batteries because a sudden loss of power could cause the chip to reset. There are a variety of methods to reprogram an EEPROM however, the majority of them require that the vehicle be in a particular condition at the time of. It may be necessary, for example, to disconnect the ECU and battery or to remove the chip and place it on the test board. Then the contents of the EEPROM can be read using an EEPROM reader and copied to a different chip. This process can be time-consuming and it may be difficult to get the right data. Most people prefer to have their vehicles reprogrammed by professionals instead of doing it at home. Find a reputable auto locksmith with advanced tools who know what they do. This will ensure that the key is working and is programmed correctly. To avoid problems in the future it is a good idea that the locksmith make use of genuine parts.

This involves inserting the new key into the ignition and then turning it on. Once the key is in place, you will need to wait for a few minutes before turning it off.
