How to Programming a BMW Key Fob

It's vital that locksmiths and mechanics stay up-to-date with the latest technologies in automotive technology. This includes key duplication and programming. This will allow them tackle difficult issues such as BMW key fob programming.

To program a new key start by inserting the working key into the ignition, then turning it to position 1. The dash and accessory lights should be on.

What is EEPROM?

The EEPROM chip is a non-volatile memory that can be erased or modified. It is used to store a variety of things, including serial numbers as well as other unique information that is found in nearly everything connected to Ethernet and the chip in charge cards, printers and even blood glucose monitors. It is also used to store data sequences that control microcontrollers' operations and also to allow for recovering from resets caused by power-on conditions.

The basic EEPROM chip is comprised of two field effect transistors. One of them is floating gates, and the other is a control gate. When the device is turned on the electrons are released and may be held 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 is in the "0" state there is no value. If the EEPROM is in the "1" state it has a value of 1. In between these states, there is no stored data, however it is possible to write to. EEPROMs can be erased by an extremely short amount of the voltage applied to the gate.

The EEPROM has the advantage that it can be erased and written to with no external circuitry. This makes EEPROMs extremely beneficial for systems that require frequent memory updates for remote microcontrollers for keyless systems. There are other kinds of memory chips that have similar functionality but are better suited to long-term storage.

Modern flash memory chips are popular in digital cameras and computers. They are used to store multimedia files for long-term storage and retrieval. But they aren't EEPROMs and their primary functions differ from those of real EEPROMs. However, EEPROMs continue to be used extensively due to their versatility, and their capacity to store small amounts of data in a small space.

What is OBDII?

Prior to recently the majority of car manufacturers had their own systems to diagnose problems with their vehicles. Then in 1996, the government demanded that all vehicles have an uniform system for reading diagnostic codes. This new system, which is called OBD-II, uses the same port and diagnostic code system across all makes and models of vehicles sold in the US. This means that if there is an issue with your vehicle it will be simple for any mechanic to determine what is causing the issue by plugging in a special tool.

The OBD-II reads a variety of issues within the engine and other components using an ordinary diagnostic plug. The data is saved to the computer of the car for later analysis. The system is able to detect and repair faults prior to causing 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 for later analysis. Some tools even perform advanced functions like reprogramming the ECU and providing performance enhancing options. These tools are used by auto technicians who are professionals and are generally more expensive than scanners that are merely scanning.

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 correct pins. There are a variety of protocols. The most common include SAE J1850 (KWP2000) that is used by Ford and certain GM cars ISO 14230-4, utilized in various European and Asian vehicles, and CAN. Some scanners will provide you with the code actually means, while others will just give you the code, and require a bit of internet sleuthing to find out what it means.

What is CAS Unit?

The CAS module is an BMW module that controls the car's antitheft system. The system works by reading an encoded signal from the key fob and verifying 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 not the signal is valid, the engine won't begin.

BMW CAS module failures could result in a variety of symptoms including key fob problems and alarm activation, central locking and dashboard warning lights. If you experience any of these symptoms, you should have the CAS Module examined immediately by an expert.

The CAS system uses 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 an DIN connector on the end. The VCDS is a multi-purpose device such as showing error codes and changing the timing of the ignition. It also offers a variety of security features that protect the vehicle from theft.

In addition to the ICOM VCDS, BMW vehicles are equipped with a CAS module that is integrated into the key. The CAS module is powered by the ignition coil, and is not designed to run on batteries. A transponder chip is embedded in the key to send the coded signal to the CAS module. This is transmitted via an antenna coil (loop) at the ignition lock.

CasSystem implements the logic of CAS state. You should create one instance of this class on every instrument that requires information from CAS. Multiple instances of this class may cause undesirable behavior. In addition to providing information on state, the CasSystem class also handles the display of alert messages. It does this by releasing a cas_activate_alert subject that requires event information as an object with key and priority properties. This topic specifies both the ID of the alert you wish to activate as well as its priority level. After you've activated an alert and the CasSystem will publish an alert 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 I program a BMW Key

BMW offers drivers in the Murrieta area with keyless entry, a feature that lets you to lock and unlock your car without having to use keys that are physically present. This keyless entry system is only activated after the key fob has been programmed to the car. To do this, you'll have to follow a few steps.

This process differs slightly depending on whether you're looking to pair a new key fob to your existing bmw key fob functions or are starting from scratch and don't have a working key. The first step is to insert the working replacement key fob for bmw fob in your vehicle, along with the one you'd like to program. Be sure that all the doors and windows are closed. Insert the working key into the ignition, and turn it to position one and return it quickly five times (do not start the engine). Take the key out by turning it backwards.

With the key fob still in your pocket hold the unlock button as you press the lock button (the bmw key 5 series logo) three times in a row. Release the unlock button and the door locks will be locked and unlocked themselves. Repeat this process for each additional key fob that you wish to program.

The final step is connecting your smartphone to your vehicle via Bluetooth. Log into the BMW Connected application. From there, click the BMW Digital Key setup button. This will activate the key in your smartphone and allow you to use it in conjunction with the Digital Wallet app.

After you've completed these steps the BMW key fobs are now ready to be used by the other members of your family and friends on their Corona commutes. Our service department is ready to offer more tips and tricks to get the most out of your BMW driving experience.
