What Are Car Key Programmers?

Car key programmers are devices that can replicate a transponder into the memory of a vehicle. These can be used to replace keys that have been stolen or lost. They can also be used to reset oil service lights 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 wide range of vehicles. Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while experts can use Expert Mode.

The Basics

Car key programming is a method that allows you to recode the blank chip inside your replacement key to ensure it matches the current settings of your vehicle. This allows the key to communicate with and start the vehicle. While it is possible to do this with a conventional mechanical car key, modern cars require a device called a "car key programmer." These are typically standalone devices, but they can also be integrated into more complex scanners.

There are a few factors to consider when choosing the right car key programming device. First, consider your budget. The cost of car key programming devices can vary, so it's important to select one that is within your budget. Additionally, make sure to research various models and read reviews prior to making an investment. You might also seek suggestions from other locksmiths and auto professionals.

The EEPROM Method

EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a nonvolatile CMOS chip which is used to store data in computers and other electronic devices. It is programmed using individual bytes, which can be accessible via an address. Each byte could be 1 or 0. When the byte is written on the chip, it becomes active, and when it is read, the bits are decoded into instructions.

When writing to an EPROM the source and drain terminals are grounded. A high voltage that is channeled from the control gate tunnels through the silicon oxide and into the floating gate which causes electrons to flow through it and then become trapped. This causes the gate to change its contents from a 0 into a 1. If the voltage is removed the gate is uncharged, and the contents of the EEPROM are erased.

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


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

This process can be time-consuming and can be difficult to find the correct data. Most people choose to have their cars reprogrammed professionally instead of doing it at home. It's best to find an auto locksmith who is reputable, has access to advanced tools and is aware of what they are doing. This will ensure that the key will work and is properly programmed.
