Customers might require a new key fob as their old one has been lost or they might require to copy transponder codes on a replaced module. It may take a specialist just a few minutes to program new keys. It is risky for someone who is not experienced to attempt this without the proper tools and equipment. On-Board programming Modern key fobs go beyond an ordinary remote control that lets you to start your car and open the rear hatch. Transponders connect to the vehicle via an antenna and transmit data such as an ID code or VIN. This is how the vehicle determines who has the key and can unlock doors and start the engine. Transponders also have to be programmed using the immobilizer codes. Some vehicles can be programmed through a simple sequence of steps, whereas other require special software and advanced key programming tools. If you're working with a vehicle that has onboard programming, the owner's guide or an Internet search for “onboard programming steps for X vehicle” will give you the information you require. In some cases keys will need to be cloned, which means that the new key needs to have the same immobilizer code as the original one. This is accomplished using a specialized key programming tool that harvests the code from the module and then burns it onto the new key. Some vehicles require the transponder be completely reprogrammed. This is possible with a J2534 connection however, it usually it requires the removal of the module. You will need a special key programming tool and a dealer-grade software if your vehicle has an encrypted transmission. These tools are costly and should only be used under the supervision of a locksmith who is certified.

Programming EEPROMs EEPROM is a kind of non-volatile memory which stores data even when the power is turned off. It is used to store settings for configuration as well as sensor calibration data as well as firmware updates and other vital information across a variety of electronic devices. It is also reprogrammable multiple times making it an ideal choice for applications requiring frequent updates. This kind of memory is typically cheaper than ROM and provides faster write and read speeds. If you're a locksmith and need to reprogram a chip in an automobile you'll require a special device called an automotive EEPROM programmer. This device is capable of reading the EEPROM and cloning it to another chip. This allows you to test different ECUs without harming the original. It's a great tool for anyone working on vehicles. The EEPROM is a main controller of the vehicle's immobilizer. If the key is within the range of the car's antenna, its unique ID number will be sent to the embedded transponder chip. The car then will ask the chip to respond and if it receives an OK signal, it will allow the engine to start. If the chip doesn't respond, the car will go into a security mode and prevent it from starting. The EEPROM is located within the Kessy module that is above the accelerator pedal. It's a black box with two electrical connectors. To access it, you'll have to take the pedal off. To remove it, you'll need to undo and pull down the single plastic clip that keeps it in its place.

Use a small screwdriver to pull the clips on the case, and then remove it. You will need to solder the board to a testboard, but this can be done by using a hot air workstation. Then, you'll need access the EEPROM using an external program and save a binary download on your computer. This will give you key information, like the VIN. Key Fob Programming The process of programming a key fob involves synchronizing the vehicle's onboard system with an electronic signal sent by the key fob.
