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 have been stolen or lost. They can also be used to reset the oil service light and tire pressure warning lights and other functions. These devices are usually bidirectional OBD II devices, which work with a variety of vehicles. Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while more experienced technicians can utilize Expert Mode. The Basics Car key programming is a process 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 with the vehicle and ensures that the key will be able to start and run the engine. While it is possible to accomplish this using a regular mechanical car key, modern cars require a device referred to 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 most effective car key programming program for your requirements, there are a few essential aspects that you need to keep in mind. First, consider your budget. The price of car key programming devices can differ, so it's crucial to choose one that fits within your budget. Before purchasing do some research on different models and read customer reviews.

EEPROM Method The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a non-volatile CMOS chip which is used to store information in computers and other electronic devices. It can be programmed to store individual bytes which can be accessed via an address. Each byte could be one or zero. When the byte is written on the chip, it becomes active and, when it is read the bits are decoded into instructions. When writing to an EPROM, both the drain and source are grounded. A high voltage from the control gate is absorbed into the silicon oxide and is able to reach the floating gate. This causes electrons to flow in to it and then become trapped. This causes the gate's content to change from a 0 to a 1. When the voltage is cut off, the gate becomes uncharged, and the contents of the EEPROM are erased. EEPROMs are often used to store calibration coefficients for sensors, bootloader configurations and also the status of remote keyless system components. They can be utilized to maintain the state of the system between power-related transitions. This is crucial for ICs powered by batteries because a sudden loss in power will cause the chip reset. There are a couple of methods to reprogram an EEPROM. However, the majority of them require the vehicle to be in a specific state. For instance, it might be necessary to disconnect the ECU from the battery, or to remove the EEPROM and then connect it to the test board. The contents of the EEPROM chip can then be read with an EEPROM Reader and copied onto another chip. It can be a lengthy process, and it can be difficult to find the right data. Most people prefer to have their vehicles reprogrammed by professionals rather than attempting this at home. Find an auto locksmith that is reputable and has advanced tools who knows what they are doing. This ensures that the key is properly programmed and will function inside the vehicle.

A professional can complete this task quickly, sometimes in less than one minute. Certain cars might require an extended procedure that can be completed by connecting the device to the OBD2 port.
