What Are Car Key Programmers?
Car key programmers are devices that can replicate a transponder into the memory of a vehicle. These are useful for replacing stolen or lost keys. They can also be used to reset the oil service light and warning lights for tire pressure and many other functions.
Most of these devices are bidirectional OBD II devices that work with a wide range of vehicles. Some, such as the Autel MaxiIM IM608S II, have an automated and guided Smart Mode that aids novices, while more experienced technicians can utilize Expert Mode.
The Basics
Car key programming is a procedure which allows you to change the chip that is blank in your replacement key so it matches the current setting of your vehicle. This allows the key to communicate with the vehicle, and ensures the key is able to start and run the engine. Although it is possible to accomplish this with a standard mechanical car key, modern cars require a device referred to as a "car key programmer." These are usually standalone devices but are sometimes integrated into more sophisticated scanners.
When it comes down to choosing the most suitable car key programer for your needs, there are few important aspects you should be aware of. First, consider your budget. Car key programmers range in price, so it's important to find one that is within your budget. Before making a purchase do some research on various models and read user reviews.

It's not a foolproof method, but you will still require the vehicle and key(s).
Method of EEPROM
EEPROM is the abbreviation for electrically eraseable memory that is programmable (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store information. It can be programmed to store individual bytes that can be accessed using an address. Each byte may be a 1 or a 0. When the byte is written on the chip, it becomes active and when it is read the bits are decoded as instructions.
When writing into an EPROM, both the drain and source are grounded. A high voltage from the control gate tunnels into the silicon oxide before it is able to reach the floating gate. This causes electrons to flow in to the gate and get trapped. The gate's contents to change from a 0 1. If the voltage is removed, the gate becomes uncharged and the contents of the EEPROM 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 preserve the state of the system between power transitions. This is crucial for ICs powered by batteries, because a sudden loss in power can cause the chip to reset.
There are several methods to reprogram an EEPROM. However, most of them require the vehicle to be in a particular state. It may be necessary, for example, to disconnect the battery and ECU or remove the chip and then solder it to a test board. Then the contents of the EEPROM can be read using an EEPROM reader and transferred to a different chip.
It can be a time-consuming procedure, and it's difficult to find the right data. The majority of people prefer having their vehicles reprogrammed by professionals instead of doing it at home. Find an auto locksmith who is reliable and uses advanced tools who knows what they do. This ensures that the key is properly programmed and will work in the vehicle.

Onboard programming is generally the fastest, while OBD2 and EEPROM methods may take longer. Onboard programming is fairly safe as long as the correct procedures and methods are adhered to.
In the majority of instances, the key or fob must be programmed to communicate with the vehicle before it is able to start the engine. The majority of newer vehicles have upgraded transponders inside their electronic keys that require a specific programer to function properly. A professional can complete this quickly, often within a minute.
Connecting the device to an OBD2 port can help with longer-lasting procedures. Certain vehicles may require EEPROM programming, which can take a few days. Therefore, the majority of these tasks should be left to experts who have access to specialist tools and a good working knowledge of car security systems.
