I can't say for sure but it sound like you either trigger the "Panic" button or alarm system if equiped. Hook the battery up (negative last) and push the "Panic" button on the key FOB.
If you don't have the FOB you may be able to reset but disconnecting the negative cable only.
If it's an alarm system, locking and then unlocking with the FOB should reset it, also using the key to turn on the ignition is supposed to reset it.
