What Are Car Key Programmers?

Car key programmers are devices that can replicate a transponder into the memory of a car. They are useful for replacing programing keys that are stolen or lost. They can also be used to reset the oil service light as well as tire pressure warning lights and other functions.

The majority of these devices are bidirectional OBD II devices that work with a wide range of vehicles. Some, like the Autel MaxiIM IM608S II, have an automated and guided Smart Mode that helps beginners while experienced technicians can use Expert Mode.

The Basics

Car key programming is a procedure that lets you recode the chip that is blank in your replacement key to ensure it matches the current settings of your vehicle. This enables the key to communicate with the vehicle, and ensures the key is capable of starting and running the engine. It is possible to do so using a mechanical car key. However, modern vehicles need the use of a device known as a "car-key programmer". These devices are typically standalone, but they can also be integrated into more sophisticated scan tools.

When it comes to selecting the best car key programmer for your requirements, there are a few key factors that you must keep in mind. First, consider your budget. The price of car key programmers may vary, so it's important to choose one that fits within your budget. Before purchasing do some research on different models and read reviews. You might also solicit recommendations from other locksmiths or auto experts.

Certain cars come with "On-Board Programming" that allows you to create an entirely new car key by following a simple process. This is not a foolproof method, but you will still require the vehicle and key(s).

The EEPROM Method

The EEPROM is an electrically eraseable programmable read-only memory (EPROM). It is a nonvolatile CMOS memory chip that is used in computers and other electronic devices to store data. It is programmed using individual bytes, which are accessible via an address. Each byte is either a 1 (or an 0). When the byte is written to the chip, it is activated, and when it is read the bits are decoded into instructions.

When writing to an EPROM, the drain and source terminals are grounded. A high voltage from the control gate tunnels into the silicon oxide and reaches the floating gate. This causes electrons to flow in to the gate and get trapped. This causes the gate's content to change from a 0 to one. When the voltage is cut off the gate is uncharged, and the contents of the EEPROM are erased.

EEPROMs can be used to store the calibration coefficients of sensors, bootloader configurations, and the status of remote keyless system components. They can also be used 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 reset.

There are a few methods to reprogram an EEPROM, but most of them require that the vehicle be in a specific condition at the time of. For instance, it might be necessary to disconnect the ECU from the battery, or to take the EEPROM out and then connect it to an test board. Then, the contents of the EEPROM can be read with an EEPROM reader and copied to another chip.

This process can be time-consuming and can be difficult to obtain the correct data. Most people choose to have their cars reprogrammed by a professional instead of doing it at home. Find an auto locksmith that is reputable and has sophisticated tools who understands what they are doing. This ensures that the key is properly programmed and can be used in the vehicle. To avoid any future issues it's best that the locksmith use genuine parts.

In most cases, a key or fob needs to be programmed in order to be able to communicate with the car before it can be used for the engine. The electronic keys found in the majority of modern cars come with improved transponders that require a special programer to work correctly. Professionals can accomplish this task quickly, sometimes within less than an hour.

Some cars may need an extended procedure to complete, which can be accomplished by connecting the device to the OBD2 port. Some cars might even need EEPROM programming procedures which can take a few days. This is why the majority of these tasks are best done by professionals with access to the right tools, and who have an understanding of car safety systems.

While this process may seem easy, it's extremely difficult to perform correctly and could cause serious damage to the vehicle's system when not done correctly. It is recommended to consult an expert before trying DIY key programming.

There are several ways to program a new car key. On-Board Key Programming is one method. This process involves placing the new key into the ignition and then turning it on.
