What Are Car Key Programmers? The car key programmers are able to clone the transponder of the vehicle. They are useful 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 are compatible with a variety of vehicles. Some, such as the Autel MaxiIM IM608S II, have an automated and guided Smart Mode that helps beginners while experienced technicians can use Expert Mode. The Basics Car key programming is a process that allows you to recode the chip that is blank in the replacement key so that it is compatible with the current settings of your vehicle. This allows the key to communicate and start the vehicle. While it is possible to accomplish this using a regular mechanical car key, modern vehicles require a device called a “car key programmer.” These are usually standalone devices but are sometimes integrated into more complex scanners. When it comes to selecting the most effective car key programming program for your needs, there are few key factors that you must be aware of. First, consider your budget. The price of car key programmers may vary, which is why it's essential to find one within your budget.

EEPROM Method The EEPROM is an electrically erasable read-only memory programmable (EPROM). It is a permanent CMOS chip which is used to store data in computers and other electronic devices. It can be programmed using individual bytes that are accessible using an address. Each byte could be a 1 or a 0. If a byte has been 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 drain and source are grounded. A high voltage from the control gate passes through the silicon oxide and reaches the floating gate. This allows electrons to flow to it and then become trapped. This causes the gate to change its contents from a zero to a 1. If the voltage is removed from the gate, it becomes uncharged and the EEPROM contents are erased. EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations as well as the statuses of remote keyless system components. They can also be used to keep state between power transitions. This is important for ICs powered by batteries as a sudden loss of power can cause the chip to reset. There are a few ways to reprogram an EEPROM however the majority of them require that the vehicle be in a specific state at the time. For example, it may be necessary to disconnect the ECU from the battery or to take the EEPROM out and solder it to an test board. The contents of the EEPROM chip can then be read by an EEPROM Reader and copied to another chip. This can be a lengthy process and it may be difficult to get the correct data. Many people opt to have their cars reprogrammed by a professional instead of trying this at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they do. This will ensure that the key is correctly programmed and will work in the vehicle. To avoid problems in the future it is a good idea for the locksmith to make use of genuine parts.

A professional can perform this task swiftly, often within less than an hour. Some cars may need an extended procedure, which can be done by connecting the device to the OBD2 port.
