What Are Car Key Programmers?

Car key programmers are devices that can replicate a transponder into the memory of a car. They are useful to replace stolen or lost keys. They can also be used to reset oil service lights and tire pressure warning lights and many more functions.

The majority of these tools are bidirectional OBD II devices that work with a broad range of vehicles. Some tools, like the Autel MaxiIM IM608S II offer an automated and supervised "Smart Mode" that helps novices, while skilled technicians can utilize the Expert Mode.

The Basics

The procedure of programming a car keys allows you to recode the chip that is blank for 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. While it is possible to accomplish this with a conventional mechanical car key, modern vehicles require a device called a "car key programmer." These are usually standalone devices but are sometimes integrated into more sophisticated scan tools.

There are a few aspects to consider when selecting the best car key programmer. First, consider your budget. The cost of car key programming devices can vary, so it's important to find one within your budget. Additionally, make sure to research various models and read reviews before making the purchase.

This is not a foolproof method, and you'll still need the vehicle and key(s).

Method of EEPROM

EEPROM is the abbreviation for electrically eraseable programmable memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers as well as other electronic devices to store information. It can be programmed with individual bytes, which can be accessible using an address. Each byte could be a 1 or a 0. If a byte has been written to the chip, it is activated. The bits are then decoded into instructions when the byte is read.

When writing to an EPROM the source and drain terminals are grounded. A high voltage from the control gate is absorbed into the silicon oxide before it gets to the floating gate. This causes electrons to flow in to it and become trapped. This causes the gate to change its content from a zero to a 1. If the voltage is removed, the gate becomes uncharged, and the contents of the EEPROM are erased.

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

There are a few ways to reprogram an EEPROM however the majority of them require that the vehicle be in a certain condition at the time of. For instance, it could be necessary to disconnect the ECU from the battery, or remove the EEPROM and connect it to the test board. The contents of the EEPROM chip can be read using an EEPROM Reader and copied to another chip.

It is best to locate an auto key programmers locksmith who is reputable, has access to the latest tools and is aware of what they are doing.
