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?
Ta
probably battery... got any spare keys to try?
