Set off alarm now cluster dead
 

I accidentally set off my alarm the other day, the car starts and I can drive it but my cluster is dead. Radio says protect, ac system is dead. I know it's the security system, but I can't clear it.
I disconnected the battery left it for 5 minutes.Reconnected and still nothing.
I tried putting the key at the Ignition, turning it on, turning it off. Locking unlocking using the remote. Nothing seems to work.
Any suggestions?
