NSX Key Replacement, San Diego County, Mobile Service

Q: Is there a remote fob for 1995-2005 NSX?

Straight answer: the factory NSX from this era did not come with an OEM remote fob or keyless entry system. But no aftermarket remote will bypass the immobilizer on 1997 and later models. Some owners have added aftermarket keyless entry, and those remotes can be programmed with a simple ignition cycle method. You still need a properly programmed transponder key to start the car.

What Changed With the NSX Key Each Generation

NA1 (3.0L V6)

1995-2001

Your first gen NSX uses a transponder key with a Honda immobilizer system. There is no remote, no fob battery, and no push button start. Just a high-security blade with a chip that talks to your ECU. Programming requires Honda PIN extraction and diagnostic tools; this is not a DIY job.

NA2 (3.2L V6)

2002-2005

Your NA2 got the bigger 3.2L engine, but the key system stayed the same. Still a transponder key with a high-security blade and Honda immobilizer. Same programming process, same tools required. The consistency is actually a good thing because it means parts availability is solid across the entire first-generation run.

🔑

Transponder Key (NA1)

1995-2001

A metal key with a thick plastic head containing a transponder chip. No buttons, no remote. You insert it in the ignition and the chip communicates with the immobilizer to let the engine start.

🔑

Transponder Key (NA2)

2002-2005

Same style as the NA1 key. High-security blade with a transponder chip in the head. No remote functions built in. If your NSX has aftermarket keyless entry, that remote is separate from the ignition key.

Acura dealers no longer service the NA-chassis NSX with any depth. Our van still does, with the right Megamos transponder, the right cutter, and the right programmer for every model year.

Common NSX Key Issues We See

🔍

Transponder Chip Failure

Collector pulls the car out after months and the only key has vanished. The NSX immobilizer from the early 1990s talks to a Megamos 13 transponder. We pull IMMO data through OBD, originate a fresh key from scratch at the car. Title or registration required.

⚠️

Immobilizer ECU Fault

NSX owners assume a no-start means a bad key. But on 2000-2005 models the immobilizer control unit itself develops faults from years of engine bay heat. We test the key first. If clean, the ECU is next, and we tell you what is going on.

🔑

High Security Blade Wear

Key feels harder to turn in the ignition or sticks in the door cylinder. Blade wear. The NSX uses a high-security blade that wears with years of daily use, and a worn blade can lock you out in a Carmel Valley lot. We laser-cut from the original code.

🔒

PIN Code Extraction Difficulty

Honda requires a 4-digit PIN to program transponder keys. We carry PIN readers and pull through OBD-II or EEPROM extraction from the ECU. On older NSX models standard methods sometimes fail because data has degraded. At the vehicle.

Programming a NSX Key Yourself

1995-2005 (Transponder Key)

No - Pro Required

No DIY self-programming for the transponder chip. The NSX immobilizer requires professional diagnostic tools and Honda PIN extraction to register a new key to the ECU. This is a locksmith or dealer job, period.

1995-2005 (Remote Only, if equipped)

Yes - DIY Possible

If your NSX has an aftermarket keyless entry remote, you can program the remote yourself using an ignition cycle method. But this only programs the lock/unlock buttons. It does not touch the transponder chip, so your car still will not start without a properly programmed key.

Common NSX Key Questions

Does my 1995 Acura NSX have a transponder key? ▼

Yes. The 1995 NSX uses a Megamos 13 (ID13) transponder system that the van reads through OBD-II. Ownership proof is required at the vehicle. We originate a fresh transponder, cut the blade to the lock cylinder code, and program everything in the driveway. Acura dealers rarely take this job anymore on a thirty-year-old chassis, and when they do, expect a tow and a wait. We charge $300-$500 and most calls are same-day across San Diego County. (619) 876-1271.

How do I program a new transponder key for my 2000 NSX? ▼

You cannot do this one yourself. The 1997-2005 NSX transponder keys require OBD-II or EEPROM programming with professional tools like the Autel IM608 or LAUNCH X431. There is no self-programming procedure for the immobilizer chip. We tackle the Honda PIN extraction and programming at the vehicle for $250-$400. Bring your VIN and registration, and we will match the correct chip to your ECU right at the car.

Can I get a replacement key if I lost all my NSX keys? ▼

Yes - but the process is more involved than a standard spare. Call (619) 876-1271 and we will walk you through it. The immobilizer needs the correct transponder chip programmed to the ECU, and with no working key to reference, we extract the PIN and program from scratch. We cut the blade by VIN code and handle everything at the vehicle. This saves you the towing fees the dealer would charge just to get your NSX through their door.

Trivia Worth Knowing

Back in 1990 the NSX became the first production car in the world to use titanium connecting rods in its engine. Aerospace-grade hardware in a road car was unheard of, and the engineering bled into the rest of the platform. Even the early immobilizer system in the NSX punched above what anything else in Honda's catalog carried at the time. Honda was not just building a supercar, they were proving a Japanese manufacturer could out-engineer Ferrari at Ferrari's own game. The transponder architecture from those years still reads with the same equipment we use on a same-year Integra GS-R.
