These devices are usually bidirectional OBD II devices, which can be used with a variety vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and supervised “Smart Mode” that helps novice technicians, while more experienced technicians can benefit from the Expert Mode. The Basics The procedure of programming a car keys allows you to change the code of the chip that is blank in a replacement key, so that it matches the vehicle's settings. This allows the key to communicate and start the vehicle.

EEPROM Method EEPROM stands for electrically erasable memory that is programmable (EPROM). It is a nonvolatile CMOS memory chip that is utilized in computers as well as other electronic devices to store information. It can be programmed with individual bytes that are accessible via an address. Each byte can be either one or zero. When a byte has been written to the chip it becomes active. The bits are then converted into instructions when the byte is read. When writing data into an EPROM the source and drain are grounded. A high voltage from the control gate tunnels through the silicon oxide and is able to reach the floating gate. This allows electrons to flow to it and then become trapped. This causes the gate's content to change from a zero to 1. When the voltage is removed the gate is uncharged and the contents of the EEPROM are erased. EEPROMs are commonly used to store calibration coefficients for sensors, bootloader configurations, and the status of remote keyless system components. They can be used to keep track of state between power changes. This is crucial for ICs powered by batteries, because a sudden loss in power can cause the chip to reset. There are several ways to reprogram an EEPROM. However, the majority of them require the car to be in a particular state. For instance, it might be necessary to disconnect the ECU from the battery or to take the EEPROM out and then connect it to a test board. The contents of the EEPROM chip could then be read with an EEPROM Reader and copied onto another chip. It can be a time-consuming procedure, and it's difficult to obtain the correct data. The majority of people prefer having their cars reprogrammed by experts rather than attempting this at home. Find an auto locksmith that is reputable and has advanced tools who knows what they are doing. This will ensure that the key is properly programmed and will work in the vehicle. It is important to make sure that the locksmith is using genuine parts to avoid problems later on.
