Works with empty PCF7935 and with original BMW keys (EMU – emulator)

How to connect CarProg to EWS:

EWS2 older immobilizer:

Old immobiliser type with Motorola processor in DIP package and 27C256 EPROM. Usually this immobiliser is fitted to E36 cars. Use A10 adapter and connect immobiliser like in picture:

Select in CarProg BMW immobiliser Menu EWS2 old immobiliser system and read EWS data.

Now you can see how many key is programmed and perform action you won. To program key just set empty PCF7935 transponder in to CarProg antenna adapter A3, select key number to program and perform key programming action.

Also see in this manual how to:

Restore old keys (in case if old key stop to work);

Delete lost transponder key;

Change EWS settings;

Check key;

Some EWS2 problems you can solve by soldering all EWS board connections.

EWS2 immobiliser:

usually used in BMW cars up to year 1996, with yellow or violet connector (white or black plastic box). Use A10 adapter and connect immobiliser like in picture:

Select in CarProg BMW immobiliser Menu EWS2 immobiliser system and read EWS data.

EWS 2 have several different software versions – after reading check if SW on CarProg screen is the same like on EWS box, if no – select EWS1 and read again.

EWS2 with processor mask 2D47J in some case can by erased while reading in the car year 1997.

EWS3 immobiliser:

used in BMW, Mini and Rover cars year 1997-2004, with black connector (white or black plastic box). Use A10 adapter and connect immobiliser like in picture:

Select in CarProg BMW immobiliser Menu EWS3 immobiliser system and read EWS data.

EWS3 with processor mask 2D47J can by erased while reading. This processor type is used in EWS3 software versions SW5, SW4 and SW3. Tested, that SW3 HW1 EWS3 memory will be lost while reading. Most common problem in EWS3 immobilizers is bad ELMOS circuit. Check if this IC temperature in working state is normal. If ELMOS is very hot – replace it first.

EWS3 immobiliser key programming by K-Line:

Used in BMW, Mini and Rover cars year 1997-2004, with black connector (white or black plastic box). Use A11 adapter, connect A11 cable to immobiliser black connector. Connect external +12V power supply to CarProg.

Follow CarProg instructions and for few seconds short 0D46J MPU pins 22 and 23 like in picture:

EWS3 with processor mask 2D47J can by erased while reading. This processor type is used in EWS3 software versions SW5, SW4 and SW3. Tested, that SW3 HW1 EWS3 memory will be lost while reading. Recover lost EWS3 data is impossible with our equipment.

Most common problem in EWS3 immobilizers is bad ELMOS circuit. Check if this IC temperature in working state is normal. If ELMOS is very hot – replace it first.

EWS Key programmer Additional functions:

1.Restore old keys: in older BMW cars equipped with EWS2 immobiliser most common problem is key variable part synchronization loosing. This happen when battery is old and bad charged. Original transponder key remote control work, but car starter relay is not operated. Remove EWS from car, connect it to CarProg like in pictures and read EWS data. Now insert not working key in CarProg antenna and Check Key. CarProg will show key number. Just deselect this key Used box and perform EWS write operation. If you don’t have car key, is possible to restore all car keys – deselect Used box for all used key.

2.Delete lost transponder key: in key data write all FFFF and perform Write EWS operation. Key will by disabled.

3.Change EWS settings: you can change EWS VIN number, mileage and perform EWS write operation. This data will by overwritten in all car keys after first engine start – in case if key is working. Also you can change EWS password, key data, EWS GM, VN, SA car coding – but be careful and not use this function if you not advanced user – you can damage car.

4.Check key: insert key in to CarProg antenna adapter and Check key validity to EWS and key number.
