How to Programming a BMW Key Fob
It is essential that mechanics and locksmiths stay current with the latest technology in automotive. This includes key duplication and programming. This will allow them tackle difficult problems like BMW key fob programming.
To program a new key, begin by inserting the working key into the ignition and then turning it to position 1. The dash and accessory lights should come on.
What is EEPROM?
The EEPROM chip is a non-volatile memory that can be erased or modified. It can be used to store various things, like serial numbers and other unique information in nearly any device connected to Ethernet. It is also the chip found in charge cards and printers as well as blood sugar monitors. It is also used to store data sequences that control the microcontrollers' operation and also to offer a method of recovering from power-on reset conditions.
The basic EEPROM chip has two field effect transistors. One has what is called floating gate, while the other is a control gate. When the device is powered by electrons, they are released from the gate and can be held in one or zero state depending on how much voltage is applied. This transistor state can be used to read the EEPROM.
If the EEPROM state is "0" and it is "0", it has no value. If the EEPROM state is "1" it has a value of 1. Between these two states, no data is stored, but it is still possible to write. EEPROMs can be erased by a short time of the voltage that is applied to the gate.
The EEPROM has the advantage that it can be erased and written to without the need for external circuitry. This makes it very useful in systems where the memory is required to be updated regularly, such as remote keyless microcontrollers for remote systems. There are different types of memory chips which have similar functionality but are better suited for long-term storage.
Modern flash memory chips are popular in computers and digital cameras. They are used to store multimedia files for long-term storage and retrieval. But they aren't EEPROMs and their fundamental functions differ from those of true EEPROMs. However, EEPROMs continue to be used extensively due to their versatility, and their ability to store minimal quantities of data in a limited space.
What is OBDII?
Prior to recently, the majority of car manufacturers relied on their own diagnostic systems for diagnosing vehicle problems. In 1996, the government mandated that all cars use a standardized system to read diagnostic codes. This new system called OBD-II utilizes the same diagnostic code and port system for all models and models that are sold in the US. This means that if you encounter a problem with your car it will be easy for any mechanic to figure out what the issue is by plugging in a specific tool.
The OBD-II reads a variety of problems within the engine as well as other parts using the standard diagnostic plug. The information is then stored in the car's computer for further analysis. This allows the system to identify and repair faults before they cause major damage. The mechanic can connect an OBD-II scan tool to the port that will display error codes and tell them where they came from.
Scan tools have more computing power than code readers and can detect more types of error codes. They also display live data graphs, and save data that can be later analyzed. Some tools can even perform more advanced functions such as programming the ECU and providing performance enhancing options. These tools are used by professional auto technicians and are generally more expensive than simple scanners.
When connecting a scan tool to the OBD-II port it will recognize the protocol it is using, and communicate with the vehicle using the appropriate pins. There are many protocols. The most well-known are SAE J1850 (KWP2000) that is used by Ford and certain GM automobiles, ISO 14230-4, used in a variety of European and Asian vehicles, and CAN. Certain scan tools will tell you what the code means. Others will give you the code and you will need to conduct some online research to figure out what it means.

The CAS module is an BMW unit which controls the antitheft feature of the car. The system works by reading the coded signal on the key fob, and then confirming it with the CAS module. The CAS module will transmit an enable signal to engine control unit if it believes the signal is valid. If it's not the signal is valid, the engine won't begin.
BMW CAS module malfunctions can cause a number of symptoms such as key fob issues central locking, alarm activation and dashboard warning lights. If you're experiencing any of these symptoms, it's important to inspect the CAS module by a professional as soon as you can.
The CAS system communicates with vehicle's engine and other systems using the BMW ICOM VCDS. The VCDS connects to the CAS with an extra cable with a DIN connector at the end. The VCDS is a multi-purpose device, including display of error codes, as well as adjusting the ignition timing. It also provides a range of security features to guard the car from theft.
In bmw keys replacement to the ICOM VCDS, BMW vehicles are equipped with a CAS component that is integrated into the key. The CAS module is powered by the ignition coil, and is not designed to work with batteries. The key is equipped with a transponder chip which transmits the coded signal. This is transmitted through loop antenna (coil) at the ignition lock.
CasSystem implements the logic of CAS state. You should create one instance of this class on each instrument that needs to receive data from the CAS. Multiple instances of this class may cause undesirable behavior. CasSystem also manages alert messages, in addition to providing state information. It does this by releasing a cas_activate_alert subject that requires event information as an object that has key and priority properties. This topic specifies the ID of the alert you'd like to activate and its priority level. Once you've activated an alert it will be displayed on the CasSystem will publish an alert on the cas_alert_displayed and cas_alert_hidden 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 to 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 the need for keys that are physically present. The keyless entry system can only activated once the key fob is programmed to the car. To do this, you'll have to follow a few simple steps.
The procedure may differ dependent on whether you're pairing a brand new BMW key fob to your existing BMW, or starting from scratch without a working BMW key. The first step is to place the working key fob in your car and the one you'd like to program. Be sure that all windows and doors are closed. Insert the working key into the ignition, and turn it to position one and quickly returning five times (do not start the engine). Remove the key by turning it backwards.
With the key fob still inside of your pocket, hold down the unlock button while you press the lock button (the BMW logo) three times fast. Release the unlock button and the door locks will unlock and lock themselves. Repeat this procedure for each additional key fob you want to program.
Connecting your smartphone to your vehicle using Bluetooth is the last step. Log in to the BMW Connected application. The BMW Digital Key setup button will appear. This will activate the key on your smartphone and allow you to use it in conjunction with the Digital Wallet app.
Once you've completed these steps, the BMW key fobs are now ready to be used by the other members of your family as well as your friends during their Corona commutes. Our service department is ready to give you more tips and tricks to have a successful BMW driving experience.
You may also need to replace the battery on your BMW's key fob. It's a fairly simple job that can be completed at home. To replace the battery, all you have to do is remove the cover for your key fob and carefully remove the old battery, then replace it with a new CR2032. The keys will be back and on the road in no time.
