2017 BMW 4 Series Smart Key Replacement - Fast, Affordable & Professional
Worst case on a 2017 BMW 4 Series is an all-keys-lost where another locksmith already attempted the job and left the FEM or BDC module in a corrupted state. A bad EEPROM write or power interruption mid-procedure can lock the module so it rejects all programming attempts. Some locksmiths see that error and tell you to tow it to the dealer. Others tell you the module is dead.
A customer's BMW was at a Euro auto shop in Otay Mesa. The shop had called another locksmith for a key on his 4 Series, and that locksmith attempted an FEM unlock, got an error, and left. The module was in a fault state and the car was completely dead. The shop called me.
I brought my ACDP bench tool. I recovered the backup, patched the corruption, wrote it back, and generated a fresh key from the restored data. His smart key, FCC ID NBGIDGNG1, was a 4-button fob. The module came back online and the car accepted the new key on the first attempt. I showed the shop team what went wrong so they'd know what to look for if it ever came up again.
Total was about two hours, which is longer than normal. His bill was $361. The alternative was a flatbed to BMW, a potential module replacement at $651 or more, and a week without his car. I carry bench tools specifically for BMW module recovery jobs.

Fast work, lasting impressions
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
“Tim went above and beyond. I struggled all day trying to program a new FOB and nothing worked. Tim helped me patiently, even recommending cheaper options since I was on a tight budget. He eventually came all the way to Ojai late at night and fixed everything.”
“My key fob stopped working while I was at Oxnard Harbor and I thought I was going to need a tow. EZ Car Keyz showed up fast, programmed a new fob, checked everything carefully, and made sure the car was fully functional before leaving.”
