🔧 PRO TIP
The 2002 Q45 remote head key is a combined unit: the transponder chip and the remote are built into the same fob body. Lose the fob, you lose both functions at once. The battery is a CR1616, which is thinner than the more common CR2032 and CR2025 cells, so hardware stores sometimes don't stock it. If the remote range goes short before the fob stops working entirely, that's the CR1616 fading. Swap it before assuming the fob needs programming. Also worth knowing: this generation Q45 does have a physical key blade integrated into the fob, and the driver door has a keyhole for manual entry when the battery is fully dead. Use it.

2002 Infiniti Q45 Remote Head Key Replacement - Fast, Affordable & Professional

Out in San Pasqual Valley, a building superintendent came to me with a three-key problem and a hard deadline attached to it.

He ran a luxury apartment complex in Escondido and drove a 2002 Q45 as his personal vehicle. He also kept two company vehicles on-site for maintenance calls. He needed a working spare for his own car, plus spares for both of the work vehicles, because leaving any of them without a backup key in property management is asking for trouble. A tenant doesn't care that your only key is at a dealership across town when a pipe bursts at midnight.

The dealer quoted him per key, and the total across three vehicles was not something the building's maintenance budget was going to absorb quietly. Beyond the cost, he couldn't pull vehicles off-site one at a time. The complex needed at least one running at all hours.

I came to him. Late afternoon, met him in the complex parking lot while he was fielding tenant calls between our sessions together.

For his Q45, the job was cutting a new blade to the vehicle and programming the transponder and remote functions through the diagnostic port. The fob uses a 4-button layout with the factory FCC ID printed on the back. Before adding multiple keys on a job like this, I back up the immobilizer module data first. It's a safety step that costs a few minutes and can save the whole job if something unexpected happens mid-sequence.

He handled two tenant calls while I worked through all three vehicles. Every key got tested individually: remote lock, unlock, the blade in the ignition, the whole sequence.

Three vehicles, one visit, no tow, no appointment wait. He kept everything on-site the whole time. The dealer comparison came up once while I was packing up. He just shook his head and said he wished he'd called sooner.

“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.”

Infiniti Q45 Mobile Service FAQ

Real costs, no dealer surprises

How long does a 2002 Infiniti Q45 key replacement take?
For a standard add-a-key on the Q45, plan on 30 to 45 minutes on-site. That covers cutting the blade to your vehicle, programming the transponder through the OBD port, syncing the remote functions, and testing everything before I leave. All-keys-lost takes longer. When there are no working keys present, I have to pull the immobilizer PIN through the diagnostic port and go through a full security reset before registering new keys. That pushes the on-site time to roughly 60 to 90 minutes depending on how the module responds. Either way, I'm not leaving until the key starts the car and the remote works.
