2015 BMW 3 Series Smart Key Replacement - Fast, Affordable & Professional
A customer at the VFW near Lakeside Proper told me he'd already paid another locksmith for a 2015 BMW 3 Series key that never started the car. The engine cranked but the immobilizer killed it immediately. The other locksmith blamed the CAS module and walked away.
The CAS was fine. The locksmith had skipped the ISN read from the DME. BMW requires the key, the CAS, and the DME to all share the same internal security number. Without that three-way match, the engine computer won't release fuel. It's not optional.
I used my HU92 Lishi to verify the blade cut, then connected through OBD. I read the CAS3 data, pulled the ISN, and reprogrammed the key with the complete security sync. His fob, FCC ID NBGIDGNG1, was a 4-button slot key. Engine start was clean on three consecutive tests. I showed him the IM608 screen confirming the ISN match between the CAS, DME, and key so he could see for himself that the three-way sync was complete.
He paid me $383. Dealer charges $685 for the same work. He'd already paid the first locksmith too, which was money gone. But I could make sure the job was done right this time.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”
“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”
