Ford key panel code

I'm certain my 2006 Ford Freestyle has been entered - twice - with no damage - I know the doors were locked - once about a year ago my Garmin was taken. This weekend I opened the doors with the fob and found our two flashlights on the drivers seat; they had been in the glove box, and my stash of parking meter quarters was gone - Is there a universal OPEN code that someone could use to get in the car?.

I'm reading my manual about how to turn off the combination code to enter the car - I thought about changing the 5 digit code, but if there is a generic OPEN code, that won't help - right?

Appreciate any hints Ed
