I'm currently living on the edge with just one key/remote. I need a spare!

Ok, I found the posts on how to swap out the blade and program the remote. I see the Ebay listings. And I get that matching the part number will make sure it works. But I've also seen vague references to backward compatibility. IE newer remotes might work with older cars.

I want to push the envelope!
My current remote does not have a trunk button.
Other people have trunk buttons, I want a trunk button!

My part number and FCC id are:
4D0 837 231 D
MZ2 410 819 6 4

Does anyone know if this model, With a Trunk Button, would work?
4D0.837.231.E
FCC ID: MZ2 410 819 6 3

Its a 99.5 1.8TQT, so its already got identity issues.
I'm the second owner, so I'm not even sure if the key/remote I have is the original.

Thanks!

 

trunk button wont do anything.. but you could nab the a6 trunk release setup and retro fit it to work.. i've thought about doing this myself.

 

Well... the other reason is that the three button remotes seem a lot easier to find. But The A6 retro trunk release sounds like it could be interesting.

 

That's weird. my 98 key fobs have trunk buttons.

 

One of the unknowns is if the one I have is original or not. But I just looked at the owners manual, and it also shows the two button remote, three if you count the panic button.
