What Are Car Key Programmers? Car key programmers are devices that replicate a transponder into the memory of a vehicle. They can be used to replace keys that have been stolen or lost. They can also be used to reset the oil service light, tire pressure warning light and many more functions. These tools are mostly bidirectional OBD II devices, which work with a variety of vehicles. Some, like the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while experts can use Expert Mode.

This is not a foolproof method and you still need the vehicle and key(s). EEPROM Method EEPROM is an acronym for electrically erasable programmed memory (EPROM). It is a non-volatile CMOS chip that stores data in computers and other electronic devices. It is programmed to store individual bits of data that can be accessed using an address. Each byte is either 1 (or a 0). Once a byte is written to the chip it is activated. The bits are then converted into instructions when the byte is read. When writing into an EPROM, both the source and drain are grounded. A high voltage from the control gate passes through the silicon oxide and gets to the floating gate. This causes electrons to flow in to it and become trapped. This causes the gate's content to change from a 0 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents 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 also be used to keep track of state between power transitions. This is important for ICs powered by batteries, because a sudden loss in power will cause the chip to reset. There are a variety of methods to reprogram an EEPROM, but most of them require that the vehicle be in a certain condition at the time of. It may be necessary, for example, to disconnect the ECU and battery or to take the chip off and place it on the test board. The contents of the EEPROM chip can be read with an EEPROM Reader and copied to another chip. This process can be lengthy, and it can be difficult to find the correct information. 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 know what they do. This will ensure that the key is working and is programmed correctly. To avoid problems in the future it's best for the locksmith to use genuine parts.

The electronic keys in most newer cars are equipped with enhanced transponders, which require a special programer to function correctly. A professional can do this fast, often in as little as one minute. Connecting the device to an OBD2 port can aid in the process of.
