Are you wanting a code for a Pronto or some other remote/software?
Philips has short code formats for the RC5 codes (see Classic Pronto FAQ - link at bottom/top of page).
If you have an editor capable of entering an RC 5 code, try System of 20 (which is from the binary representation '10100' and is 14 in hexadecimal) which is the Device Code and Command of 12 (Decimal 12 = hexadecimal 0C).
Which will give you Philips Short code format of: 5000 0000 0000 0001 0014 000C
