2004 Honda S2000
Key Replacement - Save vs Dealer in Ventura County

Q: Do I really have to tow my S2000 to the dealer if I have no keys?

No. Towing is the dealer's preferred answer because it gets the car into their bay. It's not the only option. I handle all-keys-lost work on site. The OBD-II port does the heavy lifting, and the car doesn't need to move for any part of the process. Towing adds cost before the dealer even looks at it, and then you're waiting on their schedule. I come to the vehicle in Carpinteria and do it in one visit.

Q: How long does an all-keys-lost job take on a 2004 S2000?

Usually 45 to 60 minutes on site. The immobilizer reset has a built-in timed sequence, and you can't rush that part. Once it clears, cutting and enrolling the new key goes quickly. I test the start multiple times before I leave. Dealers tend to block more shop time than that, and then you add check-in, parts sourcing, and whatever else is going on in their service queue that day. On site at your location, it's done in a single visit.

Q: My S2000 cranks but won't start. Could it be the transponder key?

That's the classic symptom when the immobilizer doesn't recognize the key. The starter motor turns, the engine cranks, but it won't fire and run. On the 2004 S2000, a key-not-detected condition from the immobilizer will typically show a warning on the dash as well.

Q: Can I get a copy of my S2000 key made at a hardware store?

They can cut the blade, but that's it. A hardware store copy will operate the door lock cylinder and the ignition cylinder mechanically, but it won't start the car. The transponder chip still needs to be programmed to the vehicle. That part requires the right equipment and a connection to the OBD-II port. So if you go the hardware store route, you'll have a key that physically turns and does nothing else.

2004 Honda S2000 Transponder Key Replacement - Fast, Affordable & Professional

There's a self-storage facility on the edge of Carpinteria, not far from the Concha Loma neighborhood. A retired guy had been keeping his 2004 Honda S2000 in a unit there, pulling it out on weekends.

He'd watched one of my Honda key replacement videos months before any of this happened, saw the full process, and dropped my number in his phone. When his only key finally stopped being recognized, he didn't panic. He called.

The car was sitting inside the storage unit, engine off, not going anywhere. That's the part dealers don't love to deal with. Their first answer tends to be "tow it in." His first answer was calling me.

I drove out to him in Carpinteria. The key blade itself was fine, still turned the cylinder. But the car would crank and not start, and that's the tell on a transponder issue. The immobilizer wasn't seeing the chip anymore. Could be the chip gave out, could be the key had taken enough wear over the years that the signal was gone.

I connected through the OBD-II port, ran the immobilizer procedure, cut and enrolled a new key. Tested the start three times before I packed anything up. He watched the whole job the same way he'd watched the video, except this time it was his car.

He mentioned what the dealer had quoted him. I just nodded. He'd already done that math.

Honda S2000 Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys to my 2004 Honda S2000. Can you still make one?▼

Yes, and it's one of the more common calls I get on S2000s specifically because these cars often get stored, handed down, or bought at auction with keys missing. All-keys-lost on this vehicle means connecting to the OBD-II port, resetting the immobilizer to clear any previously enrolled keys, then cutting and programming a new transponder key from scratch. The old keys, wherever they are, get erased out of the system so they can't start the car. No tow needed.
