How to Programming a BMW Key Fob
In the ever-evolving technology of automobiles, it's important for locksmiths and mechanics to stay educated on key programming and duplication. This will help them tackle difficult issues such as BMW key fob programming.
Start by putting the working key into the ignition, then turn the key until it is in position 1. The dash and accessories lights should come on.
What is an EEPROM?
The EEPROM chip is a nonvolatile memory that can be erased or reprogrammed. It is used to store a variety of things, including serial numbers and other distinctive information that is found in nearly everything connected to Ethernet and the chip that is used in printers, charge cards and even blood glucose monitors. It can also be used to store data sequences that regulate the microcontrollers' operation, as well as to provide a means of recovering from power-on reset situations.
The basic EEPROM chip contains two field effect transistors. One of them is a floating gate, and the other is a control gate. When the device is powered up the electrons are released. They can be trapped either in a 0 or a 1 state based on the voltage applied. This transistor state can be used to read the EEPROM.
If the EEPROM state is "0", it is in no use. If the EEPROM state is "1" is the case, it has a value of 1. In between these states, there is no stored information, but it is able to be written to. EEPROMs can be erased by a short time of voltage applied to the gate.
The advantage of the EEPROM is that it can be erased and written into without the need for external circuitry. This makes EEPROMs very useful for systems that require frequent updates to memory like remote microcontrollers that do not require keys. There are different types of memory chips that offer similar functions, but are better suited to long-term storage.
Modern flash memory chips are used in computers and digital cameras. These are often used to store multimedia files intended for both short-term and long-term storage and retrieval. However, they aren't considered to be EEPROMs and their primary functions differ from the functions of real EEPROMs. They are still utilized, however, because of their versatility and capacity to store a small amount of data in a tiny space.
What is OBDII?
In the past, many automobile manufacturers had their own diagnostic systems to diagnose car problems. In 1996, the government mandated that all cars have a standardized system for reading diagnostic codes. The new system known as OBD-II utilizes the same diagnostic code and port system for all makes and models that are sold in the US. This means that any mechanic is able to quickly diagnose a problem with your vehicle by plugging in the specific tool.
The OBD-II reads a variety of problems within the engine as well as other parts using an ordinary diagnostic plug. The information is stored in the car's computer for further analysis. This allows the system to identify and fix any issues before they cause significant damage. The mechanic can connect an OBD-II scan tool to the port and it will display error codes and indicate where they originated.
Scan tools have a higher computing capacity than code readers and read more types of error codes. They can also display live data graphs and store data that can be later analyzed. Some tools can even perform more advanced functions such as reprogramming the ECU and providing performance enhancing options. These tools are employed by auto technicians who are professionals and are usually more expensive than simple scanners.
When connecting a scanner to the OBD-II port it will automatically recognize what protocol it is using and communicate with the vehicle by using the appropriate pins. There are a variety of protocols. The most well-known are SAE J1850 (KWP2000) that is used by Ford and some GM cars, ISO 14230-4, used in various European and Asian vehicles and CAN. Some scan tools will even tell you what the code actually means, while others will only give you the code and require some internet research to discover what it means.
What is CAS Unit?
The CAS unit is a BMW module that regulates the car's antitheft system. The system works by analyzing the encoded signal on the fob of the key, and then verifying it with the CAS module. The CAS module will transmit an enable signal to engine control unit to verify that the signal is valid. If not the signal is valid, the engine won't begin.
BMW CAS module failures can cause a variety of issues including key fob problems, central locking, alarm activation and warning lights on the dashboard. If you experience any of these symptoms, make sure you have the CAS Module checked immediately by an expert.
The CAS system communicates with the vehicle's engine and other systems using the BMW ICOM VCDS. The VCDS connects to the CAS using a special cable that has an DIN connector at the end. The VCDS is a multi-purpose device that include displaying error codes and changing the timing of the ignition. It also offers a variety of security features that protect the car from theft.
In addition to the ICOM VCDS, BMW vehicles come with a CAS component that is integrated into the key. The module is powered by the ignition coil and is not designed to run on batteries. The key is encased with a transponder chip which transmits the coded signal. The signal is transmitted via a loop antenna (coil) at the lock for ignition.
CasSystem implements the logic of CAS state. This class must be created on each instrument which needs to receive data. The creation of multiple instances of this class can result in undesirable behavior. CasSystem also manages alert messages, in addition to providing state data. In order to do this, it publishes a spare key bmw cas_activate_alert topic that needs event data in the form of an object with the key and priority properties. This topic provides the ID and possibly the suffix of the alert that you want to activate, as well as its priority level. The CasSystem will issue an alert message on the topic cas_alert_displayed and cas_alert_hidden topic (defined by CasEvents). 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, a convenient feature that allows you to lock and unlock your car without using a physical key. However this keyless entry system can only be activated if the key fob is programmed to the vehicle. To do this, you'll need follow a few simple steps.
The procedure is slightly different dependent on whether you're pairing a brand new BMW key fob with your existing BMW or if you are beginning from scratch without a working BMW key. The first step is to remove the working key fob as well as the ones you wish to program inside of your vehicle, making sure that all windows and doors are shut. Insert the working key into the ignition, turning it to one position, then return it quickly five times (do not start the engine). Remove the key by turning it backwards.
With the key fob inside of your pocket, hold the unlock button as you press the lock button (the BMW logo) three times fast. Then release the unlock button and the door locks should be locked and unlock automatically. Repeat this process for each key fob.
The last step is to connect your smartphone to your vehicle via Bluetooth. Log into the BMW Connected application. From there, click the BMW Digital Key setup button. This will enable you to use the key with the Digital Wallet App.
