I am not sure how much more clear I can be, there are no other cases available for the P38 except the 2 button.
Instead of beating around the bush how about you tell us what your issue is and what you are trying to accomplish. If your case is beat up just purchase the remote rebuild kit. As posted in other threads, including one a few topics down, it includes new buttons, batteries, battery cover and water seal. If you want more buttons for more functions it is not going to happen.
Sorry, I don't think you're getting what I'm saying.
I'm not beating around the bush about anything.
I have nothing but a simple key at the moment.
First, I was asking whether any other remote(P38 Specific) besides the one offerred for my particular (2000) vehicle is compatible. I'm not asking whether a remote for a Miata will work. There are some manufacturers that have remotes that work for multiple models(Audi), and I was wondering if the receiver in my '00 is the same as a series III, etc.
In the last few hours, I figured out that all I have to do is get a complete used two button remote, also get a replacement uncut remote shell, transfer the innards over, and sync it to my vehicle.
I did just that. All on ebay, and I should have it all in hand and worked out in a week or so.
Thanks anyway, sorry if I didn't explain myself clearly enough the first time.
