interface with a caralarm remote

Hello!
Im planning on starting a new project with propeller! A car alarm. I think i have most of it figured out, but i want a smart remotecontrol for it ofcourse. For locking and unlocking the car.
It would be real cool if i could use a remote for an already existing system. For example CarGard. Their remote is widely available for cheap, and is perfect for this. The only info i can dig up about it is that it transmits on 433mhz, and is using a jumping code system.
What am i up against here? Someone with experience on things like this?
Thank you.
Daniel

Excellent company to work with.
SparkFun sells key fobs with a Nordic wireless module inside. If you look in the second post of my index there's a link to my nRF24L01+ driver. I've also added a link to some $3 Nordic modules on eBay to post #1.
The fob only outputs four bytes but the AVR chip in the fob can be reprogrammed to use a larger packet.
Ron Czapala has figured out the button press code from the fobs.
