One Customer’s 2014 bmw 428i with Fem module lost keys, I’m using Autel MaxiIM IM608 key programmer, I got the Fem module unlock and made key.
The only way the car will crank up is when I put the key next to the steering column. The unlock and lock will not work in the keyless Go doesn’t work either.
What’s wrong and how to do?
Advice and solution:
Please kindly check the frequency of the key and FEM if is same,
I program this cars every week and I chose any position I want sometimes
I chose position 5, it doesn’t matter which position, frequency of key n
fem must be same……
Also sometimes the quality of the key matters, if it is a bad key, change key.
I have done 3rd key without disabling other keys and it is working with the keyless function and remote… It asks to put the key next to the coil and hold the start button for 10 seconds. After that the keyless function is working.
key in position 1 or 2, otherwise make sure the fem is correctly coded
How to use Key Programmer Autel IM608 to program FEM/BDC BMW AKL, the result is writing key successfully.
Note: the ISN code is just an example because as I don’t have connected the DME, I cannot read the right one but it should be the first step before access the key programming. You can do it accessing the function “ISN Code Management” and then access to “Key Learning“.
Key learning is about to start.
Read the operation guide:
1). Before the key can be written and cleared, the password must be read out first!
2) Before the key can be written or cleared, the corresponding key position must be selected.
Enter 32-digit ISN code to calculate password
