I have two key fobs for my 1993 NSX and on both the plastic loop has broken. Does anyone know where to get new key fobs preferably more sturdy metallic ones??
 
The supply of remotes dried up when Kenwood changed warehouses. All the information for Honda to contact Kenwood is obsolete....I've tracked down every address and phone number. If get around inside a Kenwood phone tree, I do not get my calls returned.

I've actually gone to the new warehouse and got nowhere. I've spent hours on the phone with customer service with Kenwood in TX. They see this is as Honda's problem. And Honda sees this as a NLA issue on a car that is 30+ years old.

I'm about ready to start cold calling Kenwood engineers on LInkedIn.

If anybody had contacts at Kenwood, please let me know. Doesn't help that Kenwood doesn't have a P/N for the remote.
 
If you just want something that works you can find out the frequency of the Kenwood remote and look for universal car remotes on AliExpress and program it (assuming you still have a remote that works).

That would be nice if it worked; but, I think not although I am open to someone else giving it a try. Most of the universal remotes that can be cloned and have application listings explicitly do not support the early Acura one button remote. The early Acura remote sends the same code whether you are arming or disarming the system, the latching between armed and disarmed is done in the master embedded in the car. Anything built in the current century does not work that way.

The Acura remote works more like a one button garage door opener. Press to open and press to close. In fact, if you could find a garage remote with the same operating frequency that might work; but, you would need to find an old style door opener remote with the settable dip switches (just like the Kenwood punch holes). I also haven't seen one of those in this century.

This really might be a case (no pun) for 3D printing a case. @Wild Turkey likes that kind of stuff. Or you go the way of completely replacing your keyless system.
 
I'd be glad to try to draft & 3D print something, or draft something for you to print yourself, but that will be a lot of work, and not everyone likes the print quality of 3D-printing with complex objects.

But I have a better idea, if you actually drive your NSX. Actually the same as @Old Guy and @I_M_Legend above. Acura remote locks was an add-on option, so you don't even need it to stay "OEM stock", and the system is shite (and starting to reach the end of its life.) Having to stay within eyesight of the lock indicator on the doors to figure out whether the one button is locking or unlocking is past annoying. So I would ditch it and install a system from @I_M_Legend (LHD) or @drew (RHD). Here's why:
  1. Plug and play, so you can easily pull it if you want for selling it more "OEM".
  2. SEPARATE lock and unlock buttons!
  3. They send an actual lock or unlock signal. So you don't have to check if you've locked it or not and you don't have the problem with wondering if the signal went through, pressing it again, and accidentally unlocking it again when you thought you were locking it.
  4. They can give you a running light flash to confirm locking or unlocking, with different flashes for locking and unlocking. Much better. There is a thread on adding this feature to the OEM unit but, having done it prior to @drew's system coming out, don't bother - just replace the whole thing.
  5. They pop the trunk remotely, which the OEM does not.
  6. Completely hidden behind the glovebox, so the OEM look is retained.
One other option, if you can stand the OEM remote system. would be to reach out to @drew (See his comment above). He collects all sorts of old electrical crap just in case, and he might have a used/broken remote you could buy and transplant your electronics into, maybe even one with non-functioning internals. If you're nervous about that, you could send it to him for the transplant? Paging @drew - want to chime in before I offer your services to everyone inappropriately?

In fairness, there isn't anything particular about LHD & RHD, just that they've made their harnesses to make it easy for mounting accordingly. But if you're adept with wiring, you can make either one work with LHD or RHD if you like the look of one remote better than the other. (No, I'm not OCD am I?)

The $3 cloning remotes work ok. They have to be trained and that is the issue: need a working remote.

Just need the 315mhz ones. They are just cheap.

I have a half a dozen used matched sets and a NOS unit. I'm gonna start selling them to fund the radio project.

Hmm. When I bought my NSX 30 years ago, I paid for it with money I'd made developing 300MHz AM radios -- for car alarms, garage door openers, wireless security systems, etc.

What's the radio project that you're funding?

I wonder if this remote might be compatible, I just ordered one from this guy- my car only has one working remote.

I am not responsible for what might happen to the electronics part/s after the item is received in the working order described. New in open box - never used. Programminginstructions and owners manual not included.

Where can I can the remote clones for $3?
 
@SENNA_GOAT that appears to be a CompuStar transmitter.

The $3 clones from AliExpress are for static codes like the early OEM transmitters.

Won't work as rolling codes is likely how CS is implemented. Should be easy enough to add in extra remotes I would think.

I'd like a 3D scan of the original remote parts with intent to have it CNCd out of billet aluminum. Not sure how to go about this or what the MOQ would be.

Sounds cool, but there's a reason those remotes are always made of RF-transparent plastic. Aluminum would severely attenuate the signal -- probably to the point of preventing the system from working at all.

Got a picture of the receiver unit? I suspect it might be one of mine.

This is the model in my NSX. Based on service records it was installed in 2014.

The model name is LD-009 13P Keyless Entry System and if you search for that you will find a few old hits on Japanese sites.
 
FYI I_M_Legend and I have freely published all the information and pinouts for a DIY solution.

Fabricating harnesses can be time consuming and expensive. Doing something like this is a challenge.

As noted by others, that is aftermarket not OEM so most of the preceding advice is not relevant. You can dig around and try and find out what brand the aftermarket system is and perhaps they can still supply a replacement. Since it is a multi button remote one of the cloneable universal remotes may work if you do not want to go with @I_M_Legend 's solution.
