MY GOODNESS!!! My local Acura dealership wanted $586 for me to activate the keyless entry on my 2003. I went to Lee's Stereo in Visalia(best shop in Central Cali in my opinion) and they installed a Viper alarm w/ keyless entry w/auto doors, trunk remote sensor, etc.... for $298 installed!!!! Man... they are good and it looks professional and works perfect.

On another note.... same dealership wanted $895 for CD Changer and I purchased mine online for $221....

Thanks for all the info from this site. I will always look for aftermarket first... I'm now a believer.

There are some items for which you can get equivalent or better quality aftermarket, and some for which OEM is likely to be superior. You happened to hit on two items for which there is an extensive aftermarket and aftermarket items are compatible with the NSX without needing to be designed for this specific car. You wouldn't necessarily find the same to hold true for most other parts of the car, where various pluses and minuses of aftermarket items (not just cost, but also fit, reliability, performance, appearance etc) need to be carefully considered.
 
I personally prefer OEM just because the NSX is pre-wired for it. I don't like the idea of having someone drill holes to install a CD changer in the trunk or splice wires to install an afermarket alarm/keyless entry system.

But that's just me.
 
The Viper is the ESP 350 and one can add on some really interesting features if it suits you. As for the "drilling", my alarm shop only drilled in the siren in a great spot and used the blinking red security deterent on the drivers door for the Viper. The splicing looks professional and I saved lots of $$$.

I've got the OEM keyless entry on my 1991, is there any way to make the horn chirp or the marker lights flash when the keyless entry is used? I have had that feature on most other cars and I now find myself not being able to use the keyless entry/lock unless I am standing close enough to the car to watch the lok stalk go up and down through the window. Sort of defeats the purpose of keyless entry in my opinion.
 
Check under the D-I-Y section of the FAQ. Tells you how, and the pitfalls of doing so. I may take the plunge soon myself, as the parking lights flashing would be great.

I went OEM keyless in my 92 a month or two ago, because I couldn't bear the thought of someone ripping my dash apart, and probably wiring it up incorrectly anyway.
 
I prefer the OEM but look at the price difference, even btw dealers ($589 - $725). The aftermarket Viper at $298.00 is a much better deal. I can't belive the OEM is worth that much more. As for the dealer in Portland, I think I will shop elsewhere.

I never get parts from my local dealer. Since I'm in So Cal, I usually get my parts from Ray Laks Honda/Acura (hondacuraworld.com) and they have it listed as $362.70. I'm not sure whether this includes the discount that they offer to NSX owners, but its still way cheaper than the prices you quoted.
 
Of course the OEM for

early models is far less expensive. I think it has to do with when they added the chip in the key that makes the later version so much more. Anyway, early model OEM keyless was only ~$130-150 from the parts guy, if I remember.

You don't need to drill any holes to mount an aftermarket CD changer. Many people have done this without drilling holes. The instructions I submited on this website you drilled holes. Even if you went back to the factory changer it would still work and you would not see the holes. Since the initial release of those instruction some of the members have found a way that doesn't require you to drill holes.

Just about any after market alarm should work. If the shop was really good and you specified you didn't want to splice into any wires they could do this as well. You also don't need to add a siren, the aftermarket alarm could be used to sound the horn like the factory alarm does. The after market alarm could also be used in conjuntion with the factory alarm. The "chip" is nothing more then a resistor in the key. I did not know the newer NSX's had this feature. But a aftermarket alarm could be used with that as well and does not require any special tools just a 5 cent resistor. Now a days you can pretty much do anything you want with an aftermarket alarm.
 
Early model is pretty easy. I think the DIY is in the FAQ. I did it couple of years ago.
 
Yes, I think you need to disconnect the battery. For some reason (operator error) I had my battery accessible, but not disconnected. When I installed the keyless, the alarm went off. The key wouldn't turn it off. I disconnected the battery and it reset. No problems after that.
 
I ordered the OEM keyless entry part for my 2002 and installed it myself according to the instructions on DIY. I am not very mechanically inclined but this was a piece of cake. Works perfectly. Thanks to NSXbill2 for the instructions. Total cost $390.00
