I'm trying to figure out how to program my second keyless remote. Well I should say, I know how to program it, but here's my issue.
I have 2 remotes. One works perfectly fine. When I do program the 2nd one, the other remote no longer works. Same thing happens visa versa... So basically, it's only letting me have one remote programmed. Any ideas..? Thanks
