2008 Honda S2000 Transponder Key Replacement - Fast, Affordable & Professional

A guy from De Luz came to me after another locksmith had already taken a shot at his 2008 S2000 and missed.

The key that locksmith made worked fine the first morning. Then it started getting inconsistent. By the end of the first week, the car would crank but not catch, or start cold and then refuse to fire up again an hour later. He thought the car had developed an electrical gremlin, which is an easy assumption to make when the symptom shows up after a key job. He had already started researching fuel pump issues and ignition coil problems before someone on a forum pointed him back at the key.

He drove out to Fallbrook to meet me. I read what was actually in the key the other locksmith had programmed. The chip was the wrong generation for this car. It was close enough to pass the first registration, but Honda's immobilizer does not stop checking after that first handshake. Over multiple start cycles it caught the mismatch and started rejecting it intermittently. That intermittent pattern is the part that sends people chasing phantom electrical problems.

I cut a new key to his vehicle, programmed it with the correct chip generation matched to his S2000, and tested it through several cycles on site before I called it done. The car fired up clean every time.

He had already paid someone once for a key that did not work. He kept the cost comparison out of it, and honestly so did I. The job was fixing it right.
