2003 Infiniti Q45 REMOTE-HEAD-KEY Replacement - Fast, Affordable & Professional
Got a call from a guy on Saviers Road in Oxnard, right in the middle of the business district. His 2003 Q45 turned over but would not fire. The security light on the dash was blinking steadily, which on these NATS5 cars means the BCM is not seeing an authorized transponder. Classic immobilizer lockout.
He had already tried his spare key. Same thing. Both keys were original from the dealer, both over twenty years old. The plastic housing on the main one had a hairline crack running right across where the 4D60 chip sits inside the blade end.
I pulled the key apart on his hood. Sure enough, the chip had shifted just enough from the crack that its alignment to the antenna ring around the ignition barrel was off. The spare had a different problem: corroded battery contacts inside the remote head from a CR1616 that had leaked at some point. The transponder chip in that one was fine, just gunked up around the board.
Cleaned the spare's board and contacts, seated a fresh CR1616, verified the transponder was reading through the antenna ring with my diagnostic tool. Then I cut a new remote head key on an NSN14 blank, cloned the working 4D60, and programmed the new CWTWB1U751 fob through OBD. Both keys starting the car, all four buttons responding.
He thought he needed a tow to the dealer. He needed ten minutes of hood work and a guy who carries the right blanks.

Five stars for showing up where they needed us
“I lost my Honda Passport key and called EZ Car Keyz. He came out and made a new key in under five minutes. Legendary service.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
