can a locksmith reprogram a car computer of these devices are bidirectional OBD II devices that work with a variety of vehicles. Some tools, like the Autel MaxiIM IM608S II offer an automated and supervised "Smart Mode" that helps novice technicians, while more experienced technicians can benefit from the Expert Mode.
The Basics
The procedure of programming a car key lets you to change the code of the chip that is blank in a replacement key, to ensure that it is compatible with the vehicle's settings. This allows the key to communicate with the vehicle, and ensures the key is capable of running and starting the engine. Although it is possible to accomplish this using a regular mechanical car key, modern vehicles require a device referred to as a "car key programmer." These are typically standalone devices, but they can also be integrated into more complex scanners.
When it comes to choosing the most suitable car key programer for your requirements, there are a few essential aspects that you must be aware of. First, consider your budget. The price of car key programming devices can vary, so it's important to select one that is within your budget.

It's not a foolproof method and you still need the vehicle and key(s).
The EEPROM Method
EEPROM is the abbreviation for electrically eraseable programmed memory (EPROM). It is a permanent CMOS memory chip that is utilized in computers and some other electronic devices to store information. It can be programmed with individual bytes, which can be accessible via an address. Each byte can be either 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 to an EPROM, both the source and drain are grounded. A high voltage channeled through the control gate passes through the silicon oxide to the floating gate, causing electrons to flow through it and then become trapped. The gate's contents to change from a 0 a 1. When the voltage is cut off, 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 as well as the status of remote keyless system components. They are also utilized to maintain the state of the system between power transitions. This is essential for ICs powered by batteries because a sudden loss in power will cause the chip to reset.
There are a few methods to reprogram an EEPROM. However, most of them require that the car to be in a certain state. It could be necessary, for example to disconnect the battery and ECU or to remove the chip and solder it onto an test board. Then the contents of the EEPROM can be read using an EEPROM reader and copied to another chip.
It can be a lengthy procedure, and it's difficult to get the right data. The majority of people prefer having their vehicles reprogrammed professionally instead of trying this at home. Find an auto locksmith who is reliable and uses sophisticated tools who understands what they do. This will ensure that the key is properly programmed and can be used inside the vehicle. To avoid any future issues it's best for the locksmith to use genuine parts.

In the majority of cases the fob or key must be programmed to communicate with the vehicle before it is able to start the engine. smart key programming that are found in many modern vehicles are equipped with upgraded transponders that require a specific programer to function correctly. A professional can complete this task quickly, sometimes within less than a minute.
Connecting the device to an OBD2 port can aid in longer-lasting procedures. Some cars might even need EEPROM programming which can take a few days. For this reason, most of these tasks should be delegated to experts who have access to specialized tools and a good working understanding of security systems for cars.
