In the constantly evolving world of automotive technology it is crucial for locksmiths and mechanics to be educated about key programming and duplication. This will help them handle complex issues such as BMW key fob programming.

What is an EEPROM?
The EEPROM is a non-volatile memory chip that can be erased and changed. It can be used to store a variety of things, including the serial numbers and other distinctive information in almost anything connected to Ethernet as well as the chip in printers, charge cards and even blood glucose monitors. It is able to store information that controls microcontrollers' operation as well as a method to recover from power-on reset situations.
The basic EEPROM chip has 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. They are trapped in a 0 or a 1 state based on the voltage applied. The EEPROM can be read by monitoring the state of these transistors.
If the EEPROM is in the "0" state it is in no use. When the EEPROM is in the "1" state it has a value of one. In between these two states, no spare data is stored, however it can still be written. The EEPROM can be erased by applying an appropriate voltage to the gate for a short period of time.
The benefit of EEPROM is that it can be erased and written to without the need for any external circuitry. This makes EEPROMs extremely useful for systems that require frequent updates to memory like remote microcontrollers that do not require keys. There are other types of memory chips which provide similar functionality, but are better suited to long-term storage.
Modern flash memory chips are popular in computers and digital cameras. These are often used to store multimedia files to be used for short-term as well as long-term storage and retrieval. However, they are not true EEPROMs and their fundamental functions differ from those of true EEPROMs. EEPROMs are still widely used, but because of their versatility and the ability to store a minimal amount of data in a limited space.
What is OBDII?
Prior to recently, the majority of automobile manufacturers had their own diagnostic systems for diagnosing issues with their vehicles. In 1996, the government ordered that all cars utilize a standard system to read diagnostic codes. This new system, known as 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 any mechanic is able to easily diagnose a problem in your vehicle by plugging it into the special tool.
The OBD-II detects various problems within the engine as well as other components using the standard diagnostic plug. The information is stored in the car's computer for later analysis. The system is able to detect and fix any issues before causing significant damage. Technicians can connect to the OBD-II port with a scan tool, which will show all error codes and show which part of the system they came from.
Scan tools have a higher computing power than code readers and are able to detect more types of error codes. They also display live data graphs and store data for later analysis. Some tools even perform advanced functions like changing the ECU and supplying performance-enhancing options. These tools are used by professional auto technicians and are usually more expensive than scanners for simple tasks.
When connecting a scanner to the OBD-II port it will detect the protocol it is using and communicate with the vehicle by using the appropriate pins. There are many protocols. The most common include SAE J1850 (KWP2000) that is used by Ford and BMW Series 1 Key certain GM cars, ISO 14230-4, used in a variety of European and Asian vehicles and CAN. Some scan tools will even provide you with the code actually means, while others will provide the code and require a bit of internet sleuthing to figure out what it means.
What is CAS unit?
The CAS unit is an BMW module that regulates the car's antitheft mechanism. The system works by analyzing the coded signal on the key fob and then verifying it with the CAS module. The CAS module will send an enable signal to the engine control unit if it believes the signal is valid. If the signal is invalid the engine won't begin.
A BMW CAS module malfunction can cause a variety of symptoms, such as key fobs not working and alarm activation issues, central locking issues and warning lights on the dashboard. If you're experiencing any of these symptoms, it's important to get the CAS module checked by a professional as soon as you can.
The CAS system uses the BMW ICOM VCDS to communicate with the engine and other vehicle systems. The VCDS connects to the CAS with a special cable that has a DIN connector at the end. The VCDS can perform a variety of functions, like showing error codes or changing the timing of the ignition. It also comes with a range of security features that protect the vehicle 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 use batteries and is powered by the ignition coil. A transponder chip is embedded in the key to transmit the encoded signal to the CAS module. The signal is transmitted through coil antenna (loop) at the ignition lock.
The CAS state logic is implemented by the CasSystem class. You must create one instance of this class on every instrument that needs to receive data from the CAS. Multiple instances of this class could cause undesirable behavior. CasSystem also manages alert messages in addition to providing state information. To do this, it publishes a cas_activate_alert topic that requires event data in the form of an object with the key and priority properties. The topic specifies the ID and optionally the suffix of the alert you wish to activate, along with the priority level. After 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 using keys that are physically present. However this keyless entry system is only activated when the key fob is programmed to the vehicle. To do this, you'll need follow a few simple steps.
