The problem with many alarm systems is when you try to disarm/disable them the alarm thinks you are trying to steal the vehicle.
You need to reset the system which you can do by just leaving the key on for 30 minutes or until the security light stops flashing. Also you can do a hard reboot by disconnecting the negative battery cable and holding it to the positive terminal for 2 minutes which discharges the capacitors and will initiate a new protocol for the alarm system.
