How to Programming a BMW Key Fob
It is essential that locksmiths and mechanics stay up-to-date with the latest technology in automotive. This includes key duplication and programming. This will enable them to tackle complex problems like BMW key fob programming.
To program a new key, begin by inserting the new key into the ignition and then turning it to position 1. The dash and accessories lights should be on.
What is EEPROM?
The EEPROM is an inert memory chip that can be erased and programmed. It can be used to store various things, including serial numbers and other unique information, in almost any device connected to Ethernet. It is the chip found in printers and charge cards, and even blood sugar monitors. It is also used to keep data sequences that govern the microcontrollers' operation and to offer a method of recovering from power-on reset situations.
The basic EEPROM chip has two field effect transistors. The floating gate is located on one side and the control gate is on the other. When the device is turned on the electrons are released. They are trapped in a 0 state or a 1 state based on the voltage applied. This transistor state can be used to read the EEPROM.
When the EEPROM is in the "0" state there is no value. When the EEPROM state is "1" is the case, it has a 1 value. In between these states, no information is stored, however it is still able to be written. The EEPROM can also be erased using a certain voltage to the gate for a short period of time.
The benefit of EEPROM is that it can be written to and erased without the need for any external circuitry. This makes it very useful for systems that is required to be updated regularly like remote keyless microcontrollers for remote systems. However, there are other memory chip types that offer similar capabilities and are better suited for long-term storage and retrieval of large files.
Modern flash memory chips, for example are extremely popular and are found in computers and digital cameras. They are commonly used to store multimedia files intended to be used for short-term as well as long-term storage and retrieval. But they aren't EEPROMs and their primary functions differ from the ones of true EEPROMs. EEPROMs are still widely used, but because of their versatility and ability to store a small amount of data in a small space.
What is OBDII?
Until recently, the majority of car manufacturers had their own methods to identify problems with vehicles. Then in 1996, the government demanded that all cars use a standardized system to read diagnostic codes. This new system, which is called OBD-II is based on the same port and diagnostic code system across all models and makes of vehicles sold in the US. This means that if you have a problem with your car it will be simple for any mechanic to pinpoint what is causing the issue by plugging in a specific tool.
The OBD-II reads a variety of errors within the engine and other parts using the standard diagnostic plug. The data is saved to the car's computer to be later analysed. The system is then able to identify and repair faults prior to damaging the car in a significant way. The mechanic can connect an OBD-II scan tool to the port, which will display the error codes and inform where they came from.
Scanners have a greater computing capacity than code readers and can read a larger range of error codes. They can also display live data graphs, and save data for later analysis. Certain tools are capable of performing complex tasks, such as reprogramming an ECU or supplying options to improve performance. These higher-end tools are typically employed by professionals in the field of automotive mechanics and are more expensive than standard code scanners.
When connecting a scanner to the OBD-II port, it will detect the protocol it is using and then communicate with the vehicle using the correct pins. There are numerous protocols, but the most common ones are SAE J1850 PWM which is utilized in Ford and some GM vehicles, ISO 14230-4 (KWP2000), which is used in a variety of European or Asian vehicles and CAN, which is used on most US-made vehicles. Some scanners will explain what the code actually means, while others will just give you the code, and require some internet research to figure out what it means.
What is CAS Unit?
The CAS module is an BMW module that manages the car's antitheft system. The system works by reading the encoded signal on the fob of the key, and then confirming it with the CAS module. If the signal is valid it is then the CAS module will send an enable signal to the engine control unit. If the signal is not valid the engine won't start.
A BMW CAS module failure can result in a variety symptoms, such as key fobs that aren't working and alarm activation issues, central locking issues and warning lights appearing on the dashboard. If you notice any of these symptoms, make sure you have the CAS Module inspected as soon as you can by an expert.
The CAS system utilizes the BMW ICOM VCDS to communicate with the engine and other vehicle systems. The VCDS is connected to the CAS by an extra cable that has a DIN connector on the end. The VCDS is a multi-purpose device, including displaying error codes and altering the timing of the ignition. It also offers a variety of security features to protect the car from theft.
In addition to the ICOM VCDS, BMW vehicles come with a CAS module that is integrated into the key. The CAS module does not require batteries and is powered by the ignition coil. The key is embedded with a transponder that transmits the coded signal. This is transmitted via coil antenna (loop) at the ignition lock.
The CAS state logic is implemented in the CasSystem class. You should create one instance of this class on each instrument that needs to receive data from the CAS. Creating multiple instances of this class could result in undesired behavior. CasSystem also manages alert messages in addition to providing state information. It does this by publishing a cas_activate_alert subject that requires event data as an object with key and priority properties. This topic specifies the ID of the alert you want to activate and its priority level. Once you've activated an alert and the CasSystem will broadcast an alert message on the cas_alert_displayed as well as the cas_alert event bus topics (defined by the CasEvents interface). It will also subscribe to the cas_master_warning_active and cas_master_caution_active topics to consume their statuses.
How do you program a BMW key
BMW offers drivers in the Murrieta area with keyless entry, an easy feature that allows you to lock and unlock your car without using the physical key. This keyless entry system only activated when the key fob has been programmed to the car. To accomplish this, you'll need follow a few steps.
The procedure may differ dependent on whether you're pairing a brand new BMW key fob with your existing BMW or starting from scratch without a working BMW key. The first step is to take the working key fob and the ones you wish to program inside of your vehicle, making sure all doors and windows are shut. Insert the working key into the ignition, and turn it to one position, then return it quickly five times (do not start the engine). Turn the key back and then take it out.
With the key fob still in your pocket hold the unlock button as you press the lock button (the BMW logo) three times quickly. Then release the unlock button and the door locks should lock and unlock automatically. Repeat this process for each additional key fob you wish to program.
The final step is connecting your smart phone to your vehicle via Bluetooth. Log in to the BMW Connected application. The BMW Digital Key setup button will be displayed. This will allow you to use the key using the Digital Wallet App.
