1996 Keyless entry with alarm. help please.
 

I have a 96 and it seems to have factory keyless entry and factory alarm. Problem is, sometimes my key's entry button will work and sometimes it won't. Is there a way to buy another aftermarket remote and program it to work with my factory alarm and keyless entry? If so, any brands?

you can go to your locksmith, they have the tech, they can make it. XD You can get a replacement from them.
