2005 Honda S2000
Key Replacement - Save vs Dealer in Ventura County

Q: Can you erase a lost or stolen key so it no longer starts my S2000?

Yes. When a new transponder key is programmed to the car, the process can clear all previously registered transponders and only enroll the keys present during that session. Any lost or stolen key gets locked out. On a car like the S2000, where the owner often only ever had one key made, this is worth doing any time you are having a new key programmed anyway.

Q: Does the 2005 Honda S2000 key have a hidden emergency blade or a remote inside it?

No. The 2005 S2000 uses a plain transponder key. It is a single metal key with a plastic head that contains the transponder. There is no fob, no remote, no hidden slide-out blade, and no buttons. If you are locked out, a locksmith picks or decodes the door lock mechanically. That is a separate job from key cutting and programming, but both can be handled on site.

Q: A locksmith or shop already programmed a key for my S2000 but it stopped working after a few days. What happened?

This comes up more than it should with the S2000. The most common cause is a transponder that is the wrong type for this vehicle. Some aftermarket key blanks look identical on the outside but contain a different chip generation inside. The key can appear to program successfully and even start the car a handful of times before the immobilizer rejects it during a deeper verification cycle after several start sequences. The fix is not re-programming the same key.

Q: Can I get a second key for my S2000 made from the original, or does the car need to be present?

The car needs to be present for programming. Cutting the blade can be done from the original key or by decoding the lock, but the transponder enrollment requires access to the vehicle. The programmer communicates through the car to register the new key. Bringing just the original key to a shop gets you a cut blade, not a working key. Have the car present and the job gets done right, start to finish, in one visit.

2005 Honda S2000 Transponder Key Replacement - Fast, Affordable & Professional

I got a call from a guy parked off Linden Avenue in Downtown Carpinteria. He had an S2000 that cranked but would not fire, and he was convinced the car had developed some kind of electrical gremlin. He had already had a key made at a hardware shop a week or so before this happened.

The S2000 is a sports car with a tight cockpit, a low seating position, and an ignition barrel right where your knee wants to be. It is not a complicated key system, but it is unforgiving if the transponder is not properly enrolled. The hardware shop cut the blade off his original, which was worn, but they had no way to program the transponder. So the blade fit the lock, the engine cranked, and the immobilizer shut everything back down before it could fire. He had been calling it an electrical problem for a week.

I got there, confirmed the blade was cut correctly by checking it against the lock, then pulled out the programmer and enrolled the transponder to his car. First try, it fired right up. He sat there for a second like he was waiting for it to die again.

He mentioned a dealer in the area had quoted him for the full job, and what I charged was a fraction of that. More importantly, he did not have to tow the car anywhere or leave it overnight.

Honda S2000 Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on a 2005 Honda S2000?▼

Call a mobile locksmith before you call a tow truck. All-keys-lost on the S2000 means the car needs a new key cut to the ignition and a transponder enrolled with no working reference key present. That is a standard job with the right programmer. A dealer will want the car on their lot, which means a flatbed tow on top of the key cost.
