What Are Car Key Programmers?
Car key programmers are devices that replicate a transponder into the memory of a vehicle. These can be used to replace keys that have been lost or stolen. These can be used to reset oil service light and tire pressure warning lights and many other functions.
Most of these tools are bidirectional OBD II devices that work with a variety of vehicles. Certain tools, like the Autel MaxiIM IM608S II offer an automated and guided "Smart Mode" that helps beginners, while experienced technicians can use the Expert Mode.
The Basics
The process of programming a car key lets you to recode the chip that is blank in a replacement key to ensure that it is compatible with the settings of your vehicle. This allows the key to communicate and start the vehicle. Although it is possible to do this with a conventional mechanical car key, modern vehicles require a device called a "car key programmer." These are usually standalone devices, but they can also be integrated into more complex scan tools.
When it comes to selecting the most suitable car key programer for your requirements, there are a few key factors that you should be aware of. First, consider your budget. Car key programmers range in price, so it is important to find one that is within your budget. In addition, you should research various models and read reviews before making an investment. You may also want to ask for suggestions from other locksmiths and auto experts.

Certain car manufacturers require only a licensed dealer be in a position to create new keys.

On the other hand, some vehicles come with a feature known as "On-Board Programming" that allows you to create a new key by following a simple process. It's not a completely secure system, and you'll require the key(s) and vehicle in front of you, however it could be a good way to save money on the cost of a professional service.
EEPROM Method
The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a non-volatile CMOS memory chip used in computers as well as other electronic devices to store data. It can be programmed to store individual bytes which can be accessed via an address. Each byte can be either a 1 (or an 0). If a byte has been written to the chip, it becomes active. The bits are converted into instructions when the byte is read.
When writing to an EPROM the drain and source terminals are grounded. A high voltage that is channeled from the control gate tunnels through the silicon oxide and into the floating gate, causing electrons to flow through it and become trapped. This causes the gate to change its contents from 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 the calibration coefficients of sensors, bootloader configurations and the statuses of remote keyless systems components. They can also be used to keep the state of the system between power transitions. 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 several methods to reprogram an EEPROM, but most of them require that the vehicle be in a particular condition at the time of. For example, it may be necessary to disconnect the ECU from the battery, or to take the EEPROM out and then connect it to the test board. Then, the contents of the EEPROM can be read by an EEPROM reader and transferred to a different chip.
This process can be time-consuming, and it can be difficult to obtain the correct information. The majority of people prefer having their vehicles reprogrammed by professionals rather than trying this at home. It is best to locate an auto locksmith who is reputable, has access to sophisticated tools and understands what they're doing. This will ensure that the key will work and is properly programmed. To avoid problems in the future, it's a good idea that the locksmith make use of genuine parts.
Onboard Programming
A car key programmer is a handheld device used to program new remote keys, or fobs. They can be used in the field by professional locksmiths to improve their efficiency, or by DIY customers to save money. There are three kinds of car key programmers that are onboard, EEPROM, and OBD2. Each has its own advantages and drawbacks. Onboard programming is the quickest method, however OBD2 or EEPROM may take longer. Onboard programming is relatively safe as long as the proper procedures and protocols are adhered to.
In the majority of instances the key or fob will need to be programmed to communicate with the vehicle before it can be used to start the engine. Many newer cars come with improved transponders on their electronic keys that require a specially designed programmer to function properly. A professional can accomplish this fast, sometimes in less than one minute.
Connecting the device to an OBD2 port can speed up longer-lasting procedures. Certain cars might require EEPROM programming, which can take a number of days. Therefore, the majority of these jobs should be left to experts with access to specialized tools and have a solid understanding of security systems for cars.

In most cases, a transponder chip has to be reprogrammed into the key. This requires expertise and knowledge.
It's important that you take a look at the pros and cons of DIY car key reprogramming before attempting to do it yourself. It may seem simple however, it's difficult to perform properly and can cause major system damage if not done correctly. It is recommended to consult an expert before trying DIY key programming.
