Yes... find the colored tab that matches your original #2 remote. I believe it is the blue #2 -without- the black ink, but I may be wrong about this. I'm assuming you're using a 6.3 kit? There should be an instruction book as well that lists which key is used with what receiver models. A 6.0 kit will work as well.
The 6.3 kits also have a band switch under the battery cover - ensure all your #2 remotes are on the same band... preferrably "A".
By the way, you'll want to choose something other than remote address 1 as that is the receiver's default and neighbors are likely on the same channel.
For anyone who might be interested in useless info (I know I am!) - there are 16 additional addresses available... hold sat, release, then hit #, channel up, then a number between 1 and 16, # again, then record key.
Using this method, you'll key in a number that is -16 from the address you want. So for example if you want address 27, key in 11.
