2001 clk230 kompressor alarm problem
 

Hi

I know this subject has been mentioned before, basically whenever I lock the car, the lights will flash normally, then they flash at a rapid rate, either straight away or after a short period of time, usually the alarm does not sound if they start flashing immediately, but do if the lights flash sometime later, I have tried locking the car by using ghetto key rather than the fob, but contrary to other threads I have followed, this would still appear to set the alarm system, any comments welcome.
Thanks
