Australian magazine Silicon Chip (www.siliconchip.co.au) had a
rolling-code transmitter recently. It used a 433MHz Rx/Tx pair, and
I've seen other products that use 433MHz, all claim to do 100m

========================
TX-4312RSA 4-channel keyring rolling-code transmitter assembly
RX3302D A1.5 rolling code receiver assembly
========================

The kits are available from Oatley (www.oatleyelectronics.com)
for a reasonable price, but I give you the URLs in case there's
usable info for you

I've seen keyfob/keyring cases for sale in electronic stores and
alarm companies
