2001 A4 Alarm problem

:confused: Hi there, can anyone help me. My key remote doesn't unlock or dis enable the alarm first thing in the morning. When I'm driving off the alarm is still going for about a minute and I can't use the windows and the interior light flashes for about five minutes. When I get to my destination everything is fine and the alarm sets and the central locking will work fine for the rest of the day untill the following morning when it all starts happening all over again. I've changed my remote battery but no change. Can any one help I'm racking my brain and am reluctant to take it to a dealer.

:approve: It took a while but eventually had to buy a new control centre for the central locking as the alarm, windows, interior light are all linked to the main central locking control unit. Cost £180:( but at least it's fixed.
