What Are Car Key Programmers?

Car key programmers are devices that duplicate a transponder key programmer within the memory of a vehicle. They are useful to replace stolen or lost keys. They can be used to reset the oil service light and warning lights for tire pressure and many other functions.

Most of these tools are bidirectional OBD II devices that work with a variety of vehicles. Some, like the Autel MaxiIM IM608S II, provide an automated and supervised Smart Mode that aids novices, while experienced technicians can use Expert Mode.

The Basics

The process of programming a car key allows you to change the code of the chip that is blank in a replacement key to ensure that it is compatible with the car's settings. This enables the key to communicate with the vehicle, and also ensures that the key is able to start and run the engine. Although it is possible to accomplish this using a regular mechanical car key, modern cars require a device called a "car key programmer." These are typically separate devices, but can be integrated into more sophisticated scan tools.

There are several factors to consider when selecting the right car key programming device. First, consider your budget. Car key programmers range in cost, so it is essential to find one that is within your budget. Before making a purchase make sure you research different models and read customer reviews. You may also want to solicit suggestions from other locksmiths or auto experts.

This is not a foolproof system and you will still need to have the key(s) and vehicle in front of you, however it can be an effective way to save money on the cost of a professional service.

The EEPROM Method

The EEPROM is an electrically erasable programmable read-only memory (EPROM). It is a permanent CMOS memory chip used in computers as well as other electronic devices to store information. It can be programmed to store individual bits of data 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 is activated and, when it is read, the bits are decoded as instructions.

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

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

There are a couple of ways to reprogram an EEPROM. However, most of them require that the car to be in a certain state. It might be necessary, for instance to disconnect the battery and ECU or to remove the chip and then solder it to a test board. The contents of the EEPROM chip can be read using an EEPROM Reader and copied to another chip.

This can be a lengthy process, and it can be difficult to find the correct data. The majority of people prefer having their cars reprogrammed professionally instead of doing it at home. Find an auto locksmith who is reliable and uses advanced tools who know what they are doing. This ensures that the key is correctly programmed and will work in the vehicle. To avoid problems in the future it's best that the locksmith use genuine parts.

Onboard Programming

A car key programmer is a handheld device used to programme new remote keys or fobs. They can be used in the field by locksmiths who are professionals to increase their efficiency, or by DIY customers to save money. Key programmers for cars come in three varieties that include onboard, OBD2 as well as EEPROM. Each has its own advantages and disadvantages. Onboard programming is the most efficient method, however OBD2 or EEPROM can take longer. Onboard programming is generally safe as long as the proper procedures and methods are followed.

In the majority of instances, a key or fob needs to be programmed to communicate with the car before it can be used to control the engine. The majority of newer vehicles have upgraded transponders on their electronic keys, which require a special programer to function properly. Professionals can accomplish this task efficiently, often within less than one minute.

Connecting the device to an OBD2 port can aid in a longer procedure. Some vehicles may require EEPROM programming procedures, which can take days. This is why most of these tasks are best done by professionals with access to specific tools and an understanding of the car's safety systems.
