Yes, it is possible that your insurance company can and may deny or at least delay, any insurance claims for home intrusion, break ins, burglaries, or other criminal activity resulting from criminals breaking into your home using the 6 second break in! Why? Because insurance companies during their investigation to ensure an actual crime has been committed (and was not a result of owner carelessness or worse, insurance fraud), need evidence of forced break in. As the 6 second break in does not leave evidence, your claim can easily be denied.*
Worse, if you have a home security system that reports the alarm to your local police dept. and they arrive and see no forced entry, they would generally leave the home and assume it was a false alarm.
*Check with your insurance provider and/or your state insurance commission for details. Many will not provide a solid respond and simply state that its up to the claims department and their research of the crime.
