One time? Alarm issue.

[p3t3]

I dead locked the car with the fob (pressing the lock button twice) as normal, lights flashed all as normal. I got back to the car maybe 9hours later and the fob wouldn't work. I unlocked the car with the key with just one twist (should that be possible after a dead lock?). That set the alarm off and with the fob not working I couldn't turn it off. I started the engine no prob and when I turned the engine off the alarm stopped. Then I opened the door and the alarm went off again. Finally I disconnected the battery and reconnected then the fob started working after about 30secs? All working as normal now..

Any idea what was going on?
