What Are Car Key Programmers?

Car key programmers are devices that clone a transponder in the memory of a car. They are useful to replace stolen or lost keys. They can be used to reset oil service light, tire pressure warning lights and other functions.

These devices are usually bidirectional OBD II devices, which are compatible with a variety of vehicles. Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while more experienced technicians can utilize Expert Mode.

The Basics

Car key programming is a method that allows you to recode the blank chip inside your replacement key so it matches the current setting of your vehicle. This allows the key to communicate and start the vehicle. Although it is possible to accomplish this using a regular mechanical car key, modern cars require a device referred to as a "car key programmer." These are typically standalone devices, but they can also be integrated into more sophisticated scan tools.

When it comes to choosing the most suitable car key programer for your needs, there are few essential aspects that you must be aware of. First, consider your budget. The price of car key programmers can vary, which is why it's essential to choose one that fits within your budget. Before you purchase do some research on different models and read reviews.

The EEPROM Method

EEPROM stands for electrically erasable programmable memory (EPROM). It is a permanent CMOS chip that stores data in computers and other electronic devices. It is programmed using individual bytes, which can be accessed using an address. Each byte can be either a 1 (or a 0). When the byte is written on the chip, it is activated and, when it is read, the bits are decoded to give instructions.

When writing to an EPROM the source and drain are grounded. A high voltage channeled from the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow through it and get trapped. This causes the gate's content to change from a 0 to 1. When 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 status of remote keyless system components. They can also be used to preserve the state of the system between power transitions. This is especially crucial for ICs that are powered by battery, because a sudden loss of power will cause the chip to reset.

There are a few ways to reprogram an EEPROM. However, most of them require 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 the test board. Then, the contents of the EEPROM can be read by an EEPROM reader and copied to a different chip.

This can be a lengthy process and it may be difficult to find the right data. Many people opt to have their cars reprogrammed by a professional instead of doing it at home. Find a reputable auto locksmith with advanced tools who knows what they are doing. This ensures that the key is correctly programmed and will function in the vehicle.
