2005 Infiniti Q45 REMOTE-HEAD-KEY Replacement - Fast, Affordable & Professional
Out near Mandalay Village Marketplace in Oxnard, a retired guy with a 2005 Q45 called me after pricing out the dealer route. Nearest Infiniti store was over an hour each way, and they quoted him a number that did not include towing or his time. He said he almost gave up and parked the car for good.
I drove out to his place. The Q45 sat in the driveway looking like it just rolled off the lot. These third-generation F50 cars aged well if you kept them clean.
Underneath the Infiniti badge, this is a Nissan NATS-5 immobilizer system. The BCM talks to a PCF7936 (46 chip) inside the CWTWB1U751 remote head key. I connected through the OBD-II port, pulled the PIN from the BCM using my programmer, and registered a fresh key. Cut the blade on site, tested the four buttons, cycled the ignition, walked the doors.
He stood there watching the whole time with his arms crossed, not saying a word. When the engine turned over on the new key, he just nodded once. That was it. No speech. Just a nod.
He ended up with two working keys before I packed up. The dealer trip would have eaten half his day in windshield time alone, plus a flatbed if the car was not drivable. For Q45 owners this far from a dealership, mobile is not a bonus. It is the only thing that makes sense.
