What Are Car Key Programmers? Car key programmers are devices that can clone a transponder in the memory of a car. They are useful to replace stolen or lost keys. These can be used to reset oil service light and tire pressure warning lights and other lights. Most of these devices are bidirectional OBD II devices that work with a broad range of vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and controlled “Smart Mode” that helps beginners, while experienced technicians can use the Expert Mode. The Basics Car key programming is a procedure that lets you recode the blank chip inside the replacement key so that it is compatible with the current settings of your vehicle.

The EEPROM Method EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a non-volatile CMOS memory chip that is utilized in computers and some other electronic devices to store information. It can be programmed to store individual bytes which can be accessed via an address. Each byte is either 1 (or a 0). When can a locksmith reprogram a car computer has been recorded to the chip it is activated. The bits are then encoded into instructions when the byte is read. When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it gets to the floating gate. This causes electrons to flow to the gate and get trapped. The gate's contents to change from a 0 to a 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased. EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They can also be used to maintain status between power changes. This is essential for ICs powered by batteries, because a sudden loss in power can cause the chip to reset. There are a few methods to reprogram an EEPROM. However, most of them require the vehicle to be in a particular state. For instance, it could be necessary to disconnect the ECU from the battery, or remove the EEPROM and 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. This can be a lengthy process and it may be difficult to find the correct data. Most people choose to have their vehicles reprogrammed professionally instead of doing it at home. It's best to find an auto locksmith who is reputable, has access to advanced tools and is aware of what they are doing.
