What Are Car Key Programmers?

Car key programmers are devices that can duplicate a transponder within the memory of a car. These are useful for replacing keys that have been stolen or lost. They can also be used to reset the oil service light, tire pressure warning light and many other functions.

These devices are usually bidirectional OBD II devices, which are compatible with a variety of vehicles. Some, like the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode that aids novices, while experienced technicians can use Expert Mode.

The Basics

Car key programming is a procedure that allows you to recode the blank chip in the replacement key so that it is compatible with the current settings of your vehicle. This enables the key to communicate with the vehicle, and also ensures that the key is capable of starting and running the engine. While it is possible to do this using a regular mechanical car key, modern cars require a device referred to as a "car key programmer." These are typically separate devices, but can be integrated into more complex scan tools.

There are several factors to take into consideration when selecting the best car key programmer. First, consider your budget. The price of car key programmers may vary, so it's important to select one that is within your budget. Also, be sure to study different models and read reviews prior to making a purchase. You may also want to seek suggestions from other locksmiths or auto professionals.

Another factor to take into consideration is ease of usage. It is important to select an easy-to-use car key programer. Some are complicated and require a steep learning curve.

Certain cars come with "On-Board Programing" which allows you to make a new car key following a simple procedure. This is not a foolproof method, and you'll still need the vehicle and key(s).

Method of EEPROM

EEPROM stands for electrically erasable memory that is programmable (EPROM). It is a nonvolatile CMOS chip that is used to store data in computers and other electronic devices. It is programmed using individual bytes, which can be accessible via an address. Each byte may be a 1 or a 0. When a byte is written to the chip it becomes active and when it is read the bits are decoded into instructions.

When writing to an EPROM the drain and source are grounded. A high voltage that is channeled from the control gate travels through the silicon oxide to the floating gate which causes electrons to flow through 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 ceases to be charged and the contents of the EEPROM are erased.

EEPROMs are typically used to store calibration coefficients for sensors, bootloader configurations, and also the status of remote keyless system components. They can be used to maintain state between power-related transitions. This is important for ICs powered by batteries since a sudden loss of power will cause the chip to reset.

There are a couple of methods to reprogram an EEPROM. However, most of them require the vehicle to be in a particular state. It might be necessary, for example to disconnect the battery and ECU or remove the chip and place it on a test board. The contents of the EEPROM chip can be read with an EEPROM Reader and copied onto another chip.

It can be a lengthy procedure, and it's difficult to obtain the correct data. Most people prefer to have their cars reprogrammed by experts rather than 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 will work and is properly programmed. It's important to ensure that the locksmith uses genuine parts to avoid any issues later on.

Onboard programming is the most efficient method, however OBD2 or EEPROM may take longer. Onboard programming is also safe, if the correct procedures are followed.

In the majority of instances the key or fob will require programming to communicate with the vehicle before it can be used to start the engine. The electronic keys in most newer cars are equipped with improved transponders that require a special programer to work correctly. Professionals can accomplish this task quickly, sometimes in less than one minute.

Connecting the device to an OBD2 port can help with longer-lasting procedures. Certain cars might require EEPROM programming, which could take a number of days. Therefore, the majority of these tasks should be left to professionals who have access to specialist tools and a good working understanding of security systems for cars.
