The original problem may well have been due to the battery voltage in the remote dropping below 3 volts ( per battery- depending on which remote you have ).
To resync the remote with the alarm system you should fit a new battery in the remote - press both buttons on the remote for 6 seconds - then see if all is well.
Like I said , it can depend on what type of alarm remote you have there.
