alarm keeps going off?

You need to re-sync the remote.
Close doors, put key in ignition and turn on (dash lights on but DONT start engine).
Press the lock button on the key, doors should lock then unlock themselves. You may have to press the button a few times to make it work.
Remove key, get out of car and press the lock button on the key
The remote should now work the locks and alarm as normal.
