Code Alarm Remote Start Stopped Working My Key Less Remote Stopped Working Today On My 1997 Saab 900s 2.3L?

My key less remote stopped working today on my 1997 Saab 900s 2.3L? - code alarm remote start stopped working

I bought a 900 and set a time, the battery was dead, so I took the road to recharge the battery. I went to school today and had to change in order to begin to realize, then put it back in my school shop here. Both the alarm and remote key-less work.

I've tried my friends and alarm system should work, but then you show it off because the battery is hard to break the horn. So I was not able to automatically close the doors using the remote control. We have the battery in the car and have the code in the radio and it works well.

Look I checked the fuse in the car on the side and always good, I changed the batteries removed, but now my horn, alarm and remote control does not work. Does thissomething with the battery is dead? Did I mess with the central engine?

Please help!
