Due to the snow, SWMBO didn't drive the car for around 5 days. When I tried starting it up the battery was flat. I jumped started no problem and drove it around for half an hour. Turned it off and tried starting it and no problems. However, when I locked the car the hazzard lights began to flash at about double the normal speed. When I unlocked the car everything was fine. If I locked the car using just the key (not keyfob so no alarm was set) the car was fine.

I decided to change the battery to see if that was the problem. Unfortunately, even after a 50 minute run in the car after the battery change I get the same problem. Everytime I lock the car using the keyfob, the hazzards (all indicator lights) flash constantly at a very rapid speed.

Please help as SWMBO is now making mylife a misery regarding it!!!

TIA. Forgot to mention its a 2002 C180K
