How to use OBDSTAR X300 DP Program Smart Key for BWM FEMBDC

Most of the latest BMW vehicles adopt FEM/BDC modules, which must be programmed before the key programming. OBDSTAR X300 DP already updated the BMW FEM/BDC key programming software. To make the operation clear, let’s show the FEM smart key programming process with Key Mater DP as below:


To get a better understanding of BMW key programming, following three major steps and some tools will be explained first.

1.Key Information

2.Key Programming Preprocessing

3.Key Add/Delete

Before key programming, read key information of current vehicle. Then delete the lost key or add new key based on this information.

For these vehicles to be programmed for the first time with this kind of device, Key Programming Preprocessing is necessary before key adding and deleting. Key programming Preprocessing can be operated in the car or on workbench, while operating with specialized test cable on workbench is strongly recommended. FEM test cable is shown below:1

22 (1)

To read and write data on chip of FEM/BDC, it’s necessary to prepare and EEPROM. EEPROM/PIC picture is shown below:

22 (2)

Stpe1:    Key Information Reading

After connecting vehicle or test harness, select “Key Information” under BMW Immobilizer menu to read current key information:

22 (3) 22 (4) 22 (5) 22 (6)

Notice: It will remind you to operate preprocessing in this step. If the vehicle was programmed for the first time, it’s necessary to operate key programming preprocessing. If not, operate Key Add or Key Delete directly.

22 (7) 22 (8)

This is showing FEM module information. Click ”OK” to continue.

22 (9)

This is showing current key numbers, position, and ID. Based on demand, delete lost key and add new key in the position of Not Occupied/Starting during key programming.

22 (10)

Stpe2:    Key Programming Preprocessing

It’s required to operate key programming preprocessing if the vehicle was programmed with the device for the first time. After reading key information, click “OK” back to main menu and select “Key Programming Preprocessing”:

22 (11)

There are seven steps in processing. Start from the first step:

22 (12)

Step 1: Code data backup

Select and click “Code data backup”

22 (13)

22 (14)

Read the code data and click “yes” to save it with the filename by default. Or click “no” to customize filename and remember it (the filename will be helpful in step7)

22 (15)

Code data backup completed.

22 (16)

Step2: EEPROM Original Data Backup

Select “EEPROM original data backup”

22 (17)

During the step2, the screen will show a simple operation instruction. The operation process differs from the user’s programmer, here we take Key Master DP and EEPROM/PIC adapter for example. Shown as below:

Disassemble the FEM/BDC module from car or test cable, open the shell and weld the 95128/95256 chip and take it out.
22 (18)

Weld the 95128/95256 chip to the 95XXX position on the adapter board or insert to the chip holder with the chip clip, (pay attention to the direction of the chip) as following:

22 (20)
22 (21)

Then, connect the EEPROM adapter with Key Master DP, plug in the 12V power, shows as below:

22 (22)

Exit immobilizer function and go back to the main screen, then choose “EEPROM/PIC adapter”:

22 (23)

22 (24) 22 (25)

22 (26) 22 (27) 22 (28) 22 (29) 22 (30)

22 (31)

22 (32) 22 (33)

Notice: The original EEPROM data backup completed and saved with the name“FEM00000”. Disassemble 95128/95256 chip from adapter board and weld back to FEM/BDC module.

Step3: Service Mode Data Generation

Put FEM/BDC module back to car or connect with the test cable. Exit the “EEPROM/PIC adapter” function, enter Immobilizer and choose BMW vehicles, click “step 3: service mode data generation”:

22 (34) 22 (35) 22 (36)

Service mode data generation succeeded and saved directly on the Key Master DP, as the picture shows above. Click “ok” to go back to the last menu.

22 (37)

Stpe4: Service Mode Data Writing

Click “step 4: service mode data writing”:

22 (38)

22 (39)

This step needs the EEPROM/PIC adapter or other programmer to read and write 95128/95256 chip. If you use other programmer to write service mode data, you need to copy the generated service mode data from Key Master DP and reserve it on the programmer or PC computer, then write the data.

Write service mode data with EEPROM/PIC adapter as follow:

① Disassemble 95128/95256 chip again, weld it to the adapter, connect with the Key Master DP.
22 (40)

② Exit BMW Immobilizer, go back to the main menu, choose the EEPROM/PIC adapter.

22 (41) 22 (42) 22 (43)
22 (42)
22 (45)
22 (46)
22 (47)

22 (48)

Input a filename randomly, a different name from the backup EEPROM data in step 2.

22 (49)

Do not exit after the profile reserved. Click “Help” and choose the service mode data “FEM00000(Calc)”.

22 (50) 22 (51)

Make sure again the written data is right. If you use other programmer, please copy the service mode data “FEM00000(Calc)”from the position shown in the picture.

22 (52)
22 (53)

Service mode data recover completed. Click “ok” to go back to the last menu and exit EEPROM/PIC adapter function.

22 (54)

Step5: FEM or BDC module programming

Weld the 95128/95256 chip back to FEM/BDC module, put the module back to car or connect to the test cable, connect the Key Master DP with car or the OBDII for test cable. Exit EEPROM/PIC adapter function, enter key add pre menu, choose “step 5: program FEM/BDC module”.

22 (55)

After the program completed, click “ok” to go back to the last menu.

22 (57)

Step6: EEPROM Original Data Recovering

The procedures for EEPROM data recovering is the same as the service mode data writing. The only difference is the different writing data. Select the EERPOM original data saved in the step2. Operate according to the service mode writing, the data selected is as following:

After read the saved data, then click “help” and choose the saved EEPROM original data “FEM00000.BIN”.

22 (58)

22 (59)
22 (60)
EEPROM original data recovery completed. Click “ok”, exit EEPROM/PIC adapter function and weld the 95128/95256 chip back to the FEM/BDC module.

22 (61)
Step7: Code Data Recovery

Put FEM/BDC module back to car or connect with test cable, Key Master DP connect car or OBDII for test cable. Enter the menu “key programming preprocessing”, choose “step 7: code data recovery”.

22 (62)

22 (63)

22 (64)

Coding succeeded. Key add pre operation completed. Click “ok” and exit the key add pre.

22 (65)

3.Key Add

After the key add pre process, please connect car to do key add and key delete. Put the FEM/BDC modules back into car, then connect Key Master DP with the car OBD. Enter the menu, choose “key add”.

22 (66)

Then, put the key on the emergency starting position and click “ok”. Emergency starting position is on the right side of the steering column shell, a place with key sign as below:

Attach the key to the key sign as below:
22 (68)

Key Master DP will recognize the valid key and show its frequency, click “Yes” to continue.

22 (69)

Then the device will show the car key quantity, position and ID, such as the two programmed keys 00 and 02. Now we can add one key at the position 01, or from 03 to 09. We choose the position 08 here.
22 (70) 22 (72)

Put the key to be programmed on the emergency starting position, click “ok” to continue.

22 (73)

If the new key is recognized, the device will show “programming succeeded”, click “ok” to continue.

22 (74)

After key programming succeeded, the programmed key information will be read automatically. Key 08 is the new added key.

22 (75)

4.Key Delete

The operation for key delete is the same as key add. Enter key enable /disenable, read and remember the key ID. Then go to key add— key delete, choose the key to be deleted according to the prompt(the current key can not be deleted, no worried about deleting it by mistake).

Setting up an OBD II Scan Tool


Safety and Precautions

Safety comes first no matter what you are doing and setting up a scan tool is no different. Setting up an OBD Scanner isn’t as easy as one might think. There are also safety precautions you need to take in consideration. As well as, remembering to read the directions thoroughly and take notice of positioning.

Wear protective clothing and eyewear: During the course of setting up an OBD II Scan Tool, you may encounter gaseous objects, acids, and / or corrosive materials. It is advisable to wear not only protective eyewear but also clothing that can withstand corrosive substance. Gloves are also a good idea to have on hand.

Be Cautious and Aware of Risks: There are some risks that go with setting up an OBD II Scan Tool. They range from fire and burns, shocks, and spills. This is why paying attention to how your body is positioned is important; it just may keep you from being burned either by chemical or heat. Be aware of your tools and where they are placed after use. Because you are inserting the scanner in charged areas make sure you have the proper tools to work in that environment. It is also important to work in a well-ventilated area to avoid exposure to gases and other hazardous materials.

The importance of setting up an OBD II Scanner Tool

If you fail to set up an OBD II Scanner Tool you will not be able to utilize some important functions. These include enabling the power off time to be modified, turning the printer head off, and allowing scans to be retained within the internal memory. It is also helpful when it comes to upgrades and new information.

Proper procedure for Setting up an OBD II Scanner Tool

Setting up an OBD II Scanner Tool isn’t consistent across the board. It will vary depending on which OBD scanner tool you have purchased. Still no matter which tool you purchase the programming can get very involved. First you will need to download all necessary applications that you need in order for your scanner to work effectively. There are some applications that will only work with a PC; so be advised you may need access to one. These applications are imperative in allowing other areas of the Automotive Scan Tool to work. There are also other programs that you add such as Bluetooth. These programs will allow your smartphone or tablet to become a diagnostic scan tool.
Data Connectors

Most OBD II Scanner tools have connectors that will plug into your cars DLC – Data Link Connector. The connector has 16 pins or connection points that are usually color coded and match specific parts within your vehicle. They are generally located under you dash board on the drivers side. Make sure the DLC is properly connected to the various points, this is important.

Seven must- have car diagnostic tools

Hand with wrench. Auto mechanic.

These days, cars and trucks are more complex than ever. Not only are they jam packed with all of today’s most advanced mechanical components and features, but all of these sophisticated bits of machinery are all interconnected via computerized networks of interrelated car self diagnostic tools. These networks can be very useful in testing and diagnosing problems with your vehicle- but only if you have the right equipment. A lot of times, all this extra sophistication can seem like a great hassle- especially if you’re accustomed to the good old days of muscle-car simplicity where you just replace the part and fire it up. Well, for better or worse, those days are gone.

why need an obd2 scanner

The good news is there’s plenty of powerful tools available that- with a little bit of time in research- you can learn to perform complex diagnostic functions with that will give you a lot more power over the ins and outs of your car or truck than you would have had otherwise.

These Autel Scanner will give you the ability to figure out what is going on with your modern computerized vehicle, so that you can get it fixed and get back on the road.

1. Obd2 Scanner

An Auto Diagnostic tool is a diagnostic system that allows onboard computers in cars and trucks to tell you what’s wrong with the vehicle. This car diagnostic tool is used for a range of self-diagnostic and reporting purposes. Unlike the earlier, OBD-I system, the Obd2 system uses the same code designations, communication protocols, and connectors for cars made by all major manufacturers. The standardization has made the previous Obd1 almost completely obsolete.

2. Ignition Tester

Also known as a spark tester, this tool is absolutely indispensable for anything that relies on spark plugs- that means your car. Any time an engine won’t start, it’s possible that the reason is that there is no spark coming from the spark plug to get the engine started. An ignition tester allows you to diagnose the problem so that you don’t go all around your car solving every other problem whether you need to or not.

3. Airbag Tester

As you can imagine, it could be quite problematic to have a non-functional air bag and not know about it until the moment you need it. And naturally, testing your airbag by whacking your bumper with a rubber mallet is not ideal. Fortunately, there is a tool that can tell you whether or not all of the electronic components of your airbag system are working correctly without setting the safety device off.

4. Fuel Pressure Tester

Like a problem with your spark plug, a problem with low fuel pressure can cause your car or truck to fail to start- and if you can’t diagnose the problem directly, then you may have to work on several different things before finally finding the problem. A fuel pressure tester tells you where your vehicle’s fuel pressure is at, whether it’s too high or two low, enabling you to solve the problem straight away.

5. Timing Lights

A timing light is a special automotive stroboscope that mechanics use to set the ignition timing of internal combustion engines that are equipped with a distributor. Modern vehicle engines require timing lights to scan ignition timing accurately so that the timing can be adjusted to the optimal range for your vehicle.

6. Emission Analyzer

In most states, drivers are required to have their vehicles checked for proper exhaust emissions before the vehicle can be tagged and allowed to drive legally on public roads. Even if you are fortunate enough to live in a part of the country where vehicle emissions are not regulated, it still might be good for your conscience to have your emissions tested and adjusted accordingly. These Car Diagnostic Scanner are inserted into the exhaust pipe and, in addition to checking your emissions- they can also be used to diagnose a whole host of problems. It can also play an important role in certain safety checks, help with engine tuning, and certain kinds of repairs.

7. Vacuum Tester

A vacuum test is among the simplest Auto Scan Tools a mechanic can have. With a simple gauge, anyone can gain valuable insight into vacuum leaks, low compression, incorrect timing, and sticking valves just to name a few. You will need to know the vacuum specifications for your engine, and bear in mind that these gauges are adjusted for sea level. That means for every 1,000 feet your location is above sea level, you will need to subtract an inch of vacuum. The simplest check to perform is a running vacuum test. Simply start the engine and let it reach normal operating temperature. Find a vacuum port and connect the gauge. The port should be on the manifold or below the carburetor. It shouldn’t be on the air cleaner, high on top of the carburetor, or on any of the emissions control components.
