🔧 PRO TIP
The 2004 S2000 uses a Honda Type 1 transponder system with a T5 (Megamos ID13) chip in the key head. There's no remote, no fob, no battery. It's a single mechanical key with an embedded glass transponder. If the car cranks but won't fire, the immobilizer light on the dash (green key icon) will stay solid or blink. That means the ECU isn't seeing the chip. A worn key with a weak transponder signal is common on these after 20 years. The fix is a new key with a fresh T5 cloned to match, not a battery swap.

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

Got a call from a guy near Carpinteria Creek Park who had a 2004 S2000 sitting at a self-storage lot. AP2 chassis, the later revision with the 2.2L F22C1. He'd found me on YouTube months before, watching one of my Honda transponder jobs, and saved my number.

The car had been in storage for a while. He put the key in, turned it, and the engine cranked strong but wouldn't catch. Green key light on the dash just sat there glowing. Classic immobilizer rejection.

I pulled his original key out and looked at it. The blade was worn thin on the edges and the plastic head had a hairline crack right near where the T5 glass transponder sits inside. Twenty years of pocket carry will do that. The chip was still reading, but intermittently.

I used my Lishi HU101 to decode the lock directly, cut a fresh blade on site, and cloned his T5 transponder data onto a new chip using my VVDI Key Tool. No need to touch the OBD port for a clone, which is nice on these older Hondas where the immobilizer module lives in the gauge cluster and can be finicky to talk to.

Tested ignition three times. Turned over and fired every time. He just stood there holding the old key and the new one side by side, comparing the blade cuts like he was inspecting a forgery.

No dealer trip. No tow. Done right there at the storage lot.

“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.”

Honda S2000 Mobile Service FAQ

Real costs, no dealer surprises

I lost all my keys for my 2004 Honda S2000. Can you still make a new one?
Yes. All-keys-lost on a 2004 S2000 is a job I handle on site. The immobilizer on these is the older Honda Type 1 system, and the transponder is a T5 (Megamos ID13) chip. For an AKL situation, I decode the lock cylinders with a Lishi pick, cut a new key to the original depths, and register the new transponder through the immobilizer module in the instrument cluster. The old keys get erased so they can't start the car. No tow to the dealer, no waiting on a parts counter. The whole thing runs about 30 to 60 minutes depending on lock condition.
Do I need to tow my S2000 to the dealer if I have no working key?
How long does a replacement key take for a 2004 S2000?
My S2000 cranks but won't start and the green key light stays on. Is it the immobilizer?
Can I buy a blank key online and program my 2004 S2000 transponder myself?
