What Are car key programming and cutting Key Programmers?

Car key programmers are devices that duplicate a transponder within the memory of a car. These can be used 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 other functions.

These tools are mostly bidirectional OBD II devices, which can be used with a variety vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps beginners, while experienced technicians can benefit from the Expert Mode.

The Basics

The process of programming a car key allows you to reprogram a blank chip in a replacement key, so that it conforms to the 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 known as a "car key programmer." These are typically standalone devices but are sometimes integrated into more complex scanners.

There are a few factors to consider when selecting the best car key programmer. First, consider your budget. Car key programs vary in price, so it's crucial to choose one that is within your budget.

This isn't a 100% secure method, but you will still require the vehicle and key(s).

The EEPROM Method

EEPROM is an acronym for electrically erasable programmable car keys memory (EPROM). It is a permanent CMOS memory chip that is used in computers and some other electronic devices to store data. It is programmed to store individual bytes which can be accessed via an address. Each byte may be 1 or 0. Once a byte is written to the chip, it becomes active. The bits are then decoded 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 tunnels into the silicon oxide and gets to the floating gate. This causes electrons to flow in to the gate and get trapped. This causes the gate to change its content from a zero to a 1. When the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They are also used to maintain state between power changes. This is especially important for ICs that are powered by batteries since a sudden loss of power can cause the chip to reset.

There are a few methods to reprogram an EEPROM. However, the majority of them require that the car to be in a certain state. For instance, it might be necessary to disconnect the ECU from the battery, or to take the EEPROM out and connect it to the test board. Then, the contents of the EEPROM can be read with an EEPROM reader and copied to another chip.

This process can be lengthy, and it can be difficult to find the correct information. Many people opt to have their cars reprogrammed by a professional instead of doing it at home.

A professional can perform this task efficiently, often within less than one minute.

Connecting the device to an OBD2 port can aid in the process of. Some vehicles may require EEPROM programming procedures, which can take days. This is why the majority of these tasks are best left to professionals with access to specialized tools and an understanding of the car's safety systems.

Therefore, it's always recommended to consult a professional, and avoid DIY car key programming.

There are a variety of methods to program a new car key. One method is known as On-Board Key Programming. This involves placing the new key into the ignition and then turning it on.
