I'm looking for 4 replacement single channel keyfobs for my obsolete auto
garage door opener. I have 1 remaining (working) transmitter. Anyone know
where I can get them and what I should be asking for? Inside the transmitter
is an 8 way switch and the receiver has 433 printed on the board.
Is it possible to buy keyfobs that will simply learn the frequency from the
transmitter I already have.

Thanks,

Simon

Can you determine the encoder in the transmitter and decoder in the receiver?

If it's an HT12E encoder in the transmitter, and HT12D decoder in the receiver,
you can find keychain transmitter here http://www.wenshing.com.tw

We carry the encoder & decoder ICs, 433MHz transmitters, receivers, and much
more in our remote control store here http://www.rentron.com/PicBasic/RemoteControl.htm
