I have a remote with model #RF1112T Freq: 315 MHZ . It has three corresponding plug-ins with model #RF1112R. Both items have 0733 on the back. I know they worked last year. Put new batteries in the remote this year and can't get any of them to work. I must be programming wrong. Can you please tell me what to do other than throw them away?

Thanks,
Lynnette
