What Are Car Key Programmers? Car key programmers are devices that can clone a transponder in the memory of a car. These are useful for replacing keys that have been stolen or lost. These can be used to reset the oil service light as well as tire pressure warning lights and other lights. Most of these tools are bidirectional OBD II devices that work with a wide range of vehicles. Some, such as the Autel MaxiIM IM608S II, offer an automated and guided Smart Mode which aids beginners, while more experienced technicians can utilize Expert Mode. The Basics The procedure of programming a car key lets you to change the code of an uncoded chip 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 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 referred to as a “car key programmer.” These are typically separate devices, but can be integrated into more complex scanners. There are a few aspects to take into consideration when selecting the best car key programmer. First, consider your budget. Car key programmers range in price, so it is essential to find one that fits within your budget. Before purchasing make sure you research various models and read user reviews.

Some cars have “On-Board Programming” which lets you create an entirely new car key by following a straightforward process. This isn't a 100% secure method, but you will still require the vehicle and key(s). EEPROM Method The EEPROM is an electrically eraseable read-only memory programmable (EPROM). It is a nonvolatile CMOS memory chip that is utilized in computers and other electronic devices to store information. It can be programmed with individual bytes that are accessible using an address. Each byte can be either a 1 (or one of the numbers). When a byte is written to the chip, it is activated and when it is read, the bits are decoded as instructions. When writing to an EPROM the drain and source terminals are grounded. A high voltage from the control gate passes through 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 a 1. If the voltage is removed the gate is 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 maintain status between power changes. This is crucial for ICs powered by batteries, since a sudden loss of power will cause the chip reset. There are a variety of ways to reprogram an EEPROM however the majority of them require that the car be in a certain condition at the time of. It could be necessary, for instance to disconnect the ECU and battery or to remove the chip and solder it onto an test board. The contents of the EEPROM chip could then be read with an EEPROM Reader and copied to another chip. This can be a lengthy process and it may be difficult to get the right data. Most people prefer to have their vehicles reprogrammed by professionals rather than attempting this at home. Find an auto locksmith that is reputable and has sophisticated tools who understands what they do. This will ensure that the key works and is programmed correctly. To avoid any future issues it is best for the locksmith to make use of genuine parts. Onboard Programming A car key programmer is a handheld tool used to program new fobs or remotes. Locksmiths can utilize them to improve their effectiveness in the field, or DIY users can save money by using these devices. Car key programmers are available in three varieties including onboard, OBD2 and EEPROM. Each has its own benefits and disadvantages. Onboard programming is usually the most efficient, whereas OBD2 and EEPROM methods may take longer. Onboard programming is also relatively safe, as long as the correct procedures are adhered to. In most instances the key or fob will need to be programmed to communicate with the vehicle before it can be used to start the engine. The electronic keys that are found in many modern vehicles are equipped with upgraded transponders that require a special programmer to work correctly. A professional can perform this task quickly, sometimes in less than a minute. Some cars may need a longer process that can be completed 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 most of these tasks should be left to professionals who have access to the right tools, and who have an understanding of the car's safety systems. There are three situations where you might need to add car key programming capabilities to your toolkit A customer might request an extra key.

The process may seem straightforward, but it can be difficult to execute correctly and could cause serious damage to the system if not done correctly. Therefore, it is always advised to consult a professional and be cautious about DIY key programming. There are a few ways to program a new car key. One method is called On-Board Key Programming. This involves inserting the new key into the ignition and turning it ON. After inserting the key you must wait for several seconds before you turn off the ignition.
