What Are Car Key Programmers?

Car key programmers are devices that duplicate a transponder within the memory of a vehicle. They are useful to replace stolen or lost keys. 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 can be used with a variety vehicles. Some tools, like the Autel MaxiIM IM608S II offer an automated and supervised "Smart Mode" that helps novice technicians, while more experienced technicians can utilize the Expert Mode.

The procedure of programming a car keys allows you to reprogram a blank chip in a replacement key, so that it matches the settings of your vehicle. This allows the key to communicate with the vehicle, and ensures that the key will be capable of running and starting the engine. While it is possible to do this using a regular mechanical car key, modern vehicles require a device referred to as a "car key programmer."

The EEPROM Method

The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a permanent CMOS memory chip that is used in computers and other electronic devices to store data. It is programmed to store individual bytes which can be accessed via an address. Each byte can be either a 1 (or a 0). Once a byte is written to the chip, it is activated. The bits are 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 reaches the floating gate. This allows electrons to flow to the gate and get trapped. This causes the gate to change its content from 0 to 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, and the statuses of remote keyless system components. They can be utilized to maintain the state of the system between power changes. This is essential for ICs powered by batteries as a sudden loss of power will cause the chip reset.

There are a couple of ways to reprogram an EEPROM. However, the majority of them require that the car to be in a specific state. It may be necessary, for example to disconnect the battery and ECU or to remove the chip and solder it onto an test board. The contents of the EEPROM chip could then be read with an EEPROM Reader and copied onto another chip.

This process can be time-consuming, and it can be difficult to obtain the correct data. Many people opt to have their vehicles reprogrammed professionally instead of doing it at home. It is recommended to hire a trusted auto locksmith who has access to sophisticated tools and understands what they're doing.

In most instances the fob or key will require programming to communicate with the vehicle before it is able to start the engine. Most newer cars have improved transponders on their electronic keys that require a specially designed programmer to function effectively. A professional can perform this task swiftly, often in less than a minute.

Some cars may need more time to complete the process that can be completed by connecting the device to the OBD2 port. Certain cars might require EEPROM programming, which can take a few days. For this reason, most of these jobs should be left to professionals with access to specialized tools and a good working understanding of car security systems.
