What Are Car Key Programmers?
Car key programmers are devices that clone a transponder in the memory of a car. These can be used to replace keys that were lost or stolen. They can also be used to reset oil service lights as well as tire pressure warning lights and many more functions.
Most of these devices are bidirectional OBD II devices that 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
Car key programming is a method which allows you to change the blank chip inside the replacement key so that it matches the current setting of your vehicle. This allows the key to communicate and start the vehicle. While it is possible to do this with a conventional 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.
There are several factors to take into consideration when selecting the best car key programmer. First, consider your budget. The price of car key programmers may differ, so it's crucial to select one that is within your budget. Before purchasing make sure you research different models and read customer reviews.

This isn't a 100% secure method and you still need the vehicle and key(s).
The EEPROM Method
The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a nonvolatile CMOS chip which is used to store data in computers as well as other electronic devices. It can be programmed to store individual bits of data which can be accessed via an address. Each byte could be one or zero. When a byte is written to the chip, it is activated 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 gets to the floating gate. This allows electrons to flow to it and become trapped. The gate's contents to change from a 0 to a 1. When the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased.
EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless system components. They can also be used to keep the state of the system between power transitions. This is particularly important for ICs that are powered by batteries, since a sudden power loss will cause the chip to reset.
There are several methods to reprogram an EEPROM. However, most of them require the car to be in a certain state. It could be necessary, for example, to disconnect the battery and ECU or to take the chip off and place it on a test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and copied onto another chip.
It is a lengthy process, and it can be difficult to get the right data. Most people choose auto key programming near me to have their cars reprogrammed by a professional instead of doing it at home.

The electronic keys found in the majority of modern vehicles are equipped with improved transponders that require a special programer to function correctly. A professional can complete this task efficiently, often within less than an hour.
Connecting the device to an OBD2 port can aid in the process of. Some cars may require EEPROM programming, which could take a number of days.
