What Are Car Key Programmers?

Car key programmers are devices that replicate a transponder into the memory of a vehicle. They are useful to replace 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 other functions.

The majority of these tools are bidirectional OBD II devices that work with a variety of vehicles. Some tools, such as the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps novices, while skilled technicians can use the Expert Mode.

The Basics

Car key programming is a procedure that allows you to recode the chip that is blank in your replacement key so it is compatible with the current settings of your vehicle. This enables the key to communicate with the vehicle and also ensures that the key is capable of starting and running the engine. Although it is possible to do this using a regular mechanical car key, modern vehicles require a device referred to as a "car key programmer." These are usually separate devices, but can be integrated into more complex scan tools.

There are a few aspects to consider when selecting the right car key programmer. 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 purchasing do some research on various models and read user reviews.

Certain models have "On-Board Programming", which lets you create a new car key by following a simple procedure. It's not a foolproof method, and you'll still need the vehicle and key(s).

The EEPROM Method

The EEPROM is an electrically eraseable read-only memory that is programmable (EPROM). It is a nonvolatile CMOS chip that is used to store data in computers and other electronic devices. It can be programmed to store individual bits of data that can be accessed using an address. Each byte is either 1 (or a 0). When a byte is written to the chip it becomes active and, when it is read, the bits are decoded to give instructions.

When writing to an EPROM, the source and drain terminals are grounded. A high voltage from the control gate is absorbed through the silicon oxide and is able to reach the floating gate. This causes electrons to flow in to the gate and get trapped. This causes the gate to alter its content from a 0 into a 1. When the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs can be used to save the calibration coefficients of sensors, bootloader configurations as well as the status of remote keyless system components. They can also be used to preserve state between power transitions. This is especially crucial for ICs that are powered by batteries, since a sudden power loss can 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 could be necessary, for instance to disconnect the battery and ECU or to remove the chip and solder it onto an test board. The contents of the EEPROM chip can then be read by an EEPROM Reader and copied onto another chip.

It can be a lengthy process, and it can be difficult to obtain the correct data. Most people choose to have their vehicles reprogrammed professionally instead of doing it at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they do. This will ensure that the key works and is properly programmed. It's also a good idea to ensure that the locksmith is using genuine parts to avoid any issues in the future.

The majority of newer vehicles have upgraded transponders on their electronic keys that require a specially designed programmer to work effectively. Professionals can accomplish this task quickly, sometimes in less than an hour.

Certain vehicles may require an extended procedure that can be completed by connecting the device to the OBD2 port. Some cars might even need EEPROM programming, which can take days. Therefore, the majority of these tasks should be left to professionals who have access to specialized tools and a thorough understanding of security systems for cars.
