Cyrus remote control codes

I am modding a DAC and have another that is untouched so would like to compare them by switching between them using a remote control.

Both are connected to Cyrus Pre and but I don't have a remote for it.

I use an Audiolab 8000 remote to control a Cyrus CD DAD3 player which can also control the volume on the Pre but it does not change source.

From this I conclude there has to be an overlap in the codes sent by the Audiolab remote for the Cyrus components to respond. (I seem to remember using a Marantz remote to control the same CD player).

Does anyone know if the codes sent by remotes are published on the Internet?

I cannot use an universal programmable remote since I don't have one that can select source on the Cyrus Pre in order to program it.
 
Cyrus support responded to say it uses Philips RC-5 protocol.

I've found a page about it but not had a chance to read it but I'm sure there'll be a project out in t'internet where someone has made their own remote.... shouldn't be too difficult ro program a PIC, IR Led transmitter, 2 buttons to select a source.

I think I have a dead Cyrus remote that I could reuse, annoyingly it's is plastic welded together.
