What Are Car Key Programmers?
Car key programmers are devices that duplicate a transponder within the memory of a car. These can be used to replace keys that have been lost or stolen. They can also be used to reset the oil service light, warning lights for tire pressure and other functions.
Most of these devices are bidirectional OBD II devices that work with a variety of vehicles. Some, such as the Autel MaxiIM IM608S II, have an automated and guided Smart Mode that aids novices, while more experienced technicians can utilize Expert Mode.
The Basics
The process of programming a car key allows you to change the code of an uncoded chip for a replacement key so that it matches the vehicle's settings. This allows the key to communicate with and start the vehicle. Although it is possible to accomplish this with a standard mechanical car key, modern vehicles require a device referred to as a "car key programmer." These are typically standalone devices, but they can also be integrated into more sophisticated scanners.
There are a few aspects to consider when choosing the right car key programming device. First, consider your budget. The cost of car key programming devices can vary, so it's important to find one within your budget. In addition, you should study different models and read reviews prior to making a purchase. You may also seek recommendations from other locksmiths or auto professionals.
Another aspect to think about is ease of the use. It is essential to choose a user-friendly car key programmer. Many are complex and require a lengthy learning curve. Look for a program with clear instructions and a user-friendly interface that can help you get started quickly. Think about the automobiles that the key programmers can work with. In order to be a multipurpose tool for your automotive business it is crucial to select a device that can be used on a wide range of vehicles.
Certain car makers require that only a licensed dealer be able to create new keys. It is important to make sure that the model you are looking at has this capability prior to buying a car key programmer. Certain models have "On-Board Programing", which allows you to create an entirely new car key by following a simple process. It's not a completely secure system, and you'll require the key(s) and vehicle in front of you, however it is a great method to save money on the cost of a professional service.
Method of EEPROM
The EEPROM is an electrically erasable programmable read-only memory (EPROM). It is a permanent CMOS memory chip used in computers and some other electronic devices to store data. It is programmed to store individual bytes which can be accessed via an address. Each byte can be either a 1 or a 0. If a byte has been written to the chip it is activated. The bits are then converted into instructions when the byte is read.
When writing to an EPROM, both the source and drain are grounded. A high voltage from the control gate tunnels into the silicon oxide and reaches the floating gate. This allows electrons to flow to the gate and get trapped. This causes the gate to alter its content from a zero to a 1. If the voltage is removed from the gate, it is uncharged and the EEPROM contents are erased.
EEPROMs are commonly 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 the state of the system between power transitions. This is especially important for ICs that are powered by battery, since a sudden power loss could cause the chip to reset.
There are a few 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 example to disconnect the ECU and battery or remove the chip and place it on an test board. The contents of the EEPROM chip can be read by an EEPROM Reader and copied to another chip.
It is a lengthy procedure, and it's difficult to obtain the correct data. The majority of people prefer having their cars reprogrammed by a professional instead of trying this at home. It is best to locate an auto locksmith that is reliable, has access to sophisticated tools and understands what they're doing. This will ensure that the key is correctly programmed and can be used inside 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 program new fobs or remotes. They are used in the field by professional locksmiths to improve their efficiency or by DIY customers to save money. There are three types of car key programmers including onboard, EEPROM and OBD2. Each has its own advantages and drawbacks. Onboard programming is the quickest method, however OBD2 or EEPROM may take longer. Onboard programming is relatively safe as long as the proper procedures and protocols are adhered to.
In most cases the key or fob will need to be programmed to communicate with the vehicle before it can be used to start the engine. Most newer cars have improved transponders inside their electronic keys that require a specific programmer to work effectively. A professional can accomplish this fast, often in as little as a minute.
Some cars may need an extended procedure that can be completed by connecting the device to the OBD2 port. Certain cars may even require EEPROM programming which can take a few days. This is the reason that most of these jobs are best left to professionals who have access to specialized tools and an understanding of car safety systems.
