What Are Car Key Programmers?

Car key programmers are devices that replicate a transponder into the memory of a car. They are useful for replacing keys that are stolen or lost. They can also be used to reset the oil service light as well as tire pressure warning lights and many more functions.

These tools are mostly bidirectional OBD II devices, which work with a variety of vehicles. Some tools, like the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps novice technicians, while more experienced technicians can utilize the Expert Mode.

However modern vehicles require the use of a device known as a "car-key programmer". These devices are typically used as standalone devices, but can sometimes be integrated into scan tools that are more complex.

There are several factors to consider when choosing the right car key programming device. First, consider your budget. Car key programmers range in cost, car key cutting and programming so it is important to find one that fits within your budget.

EEPROM Method

EEPROM is the abbreviation for electrically eraseable programmable memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store information. It can be programmed car keys using individual bytes, which can be accessible via an address. Each byte could be a 1 or a 0. If a byte has been recorded to the chip it becomes active. The bits are encoded into instructions when the byte is read.

When writing to an EPROM, the source and drain terminals are grounded. A high voltage channeled through the control gate tunnels through the silicon oxide to the floating gate, causing electrons to flow into it and get trapped. The gate's contents to change from a zero to 1. If the voltage is removed the gate ceases to be charged, and the contents of the EEPROM are erased.

EEPROMs can be used to store calibration coefficients of sensors, bootloader configurations, and the status of remote keyless system components. They can also be used to preserve the state of the system between power transitions. This is crucial for ICs powered by batteries as a sudden loss of power will cause the chip reset.

There are a couple of methods to reprogram an EEPROM. However, most of them require that the car to be in a specific state. For instance, it could be necessary to disconnect the ECU from the battery or to remove the EEPROM and then connect it to the test board. The contents of the EEPROM chip can be read using an EEPROM Reader and copied onto another chip.

It can be a lengthy process, and it is difficult to find the right information. The majority of people prefer having their cars reprogrammed by experts rather than trying this at home.

The electronic keys in most newer cars are equipped with upgraded transponders that require a special programmer to work properly. A professional can complete this fast, often within an hour.

Certain cars might require an extended procedure that can be completed by connecting the device to the OBD2 port. Some cars may require EEPROM programming, which could take a number of days.
