These are typically bidirectional OBD II devices, which can be used with a variety vehicles. Some, like the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while experts can use Expert Mode.

Method of EEPROM The EEPROM is an electrically erasable read-only memory that is programmable (EPROM). It is a permanent CMOS memory chip that is used in computers and other electronic devices to store data. It can be programmed to store individual bytes which can be accessed via an address. Each byte is either a 1 (or a 0). If a byte has been recorded to the chip it is activated. The bits are decoded into instructions when the byte is read. When writing data into an EPROM the drain and source are grounded. A high voltage channeled from the control gate travels through the silicon oxide and into the floating gate and causes electrons to flow through it and get trapped. This causes the gate to alter its content from a 0 into a 1. If the voltage is removed the gate is uncharged and the contents of the EEPROM are erased. EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless system components. They are also utilized to maintain the state of the system between power changes. This is essential for ICs powered by batteries since a sudden loss of power will cause the chip to reset. There are several ways to reprogram an EEPROM however, the majority of them require that the vehicle be in a specific condition at the time of. It might be necessary, for example to disconnect the ECU and battery or remove the chip and solder it onto a test board. The contents of the EEPROM chip could then be read using an EEPROM Reader and then copied onto another chip. This can be a lengthy process and can be difficult to find the correct data. Many people opt to have their vehicles reprogrammed professionally instead of doing it at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they are doing. This will ensure that the key works and is properly programmed. It is also a good idea to make sure that the locksmith uses genuine parts to avoid problems later on.
