WiFi blocker

Hey guys. Not sure if this is the correct place to post. But a few nights ago my car was rummaged through. I have camera system that just so happened to go down for 15 minutes during the rummage. They didn’t take anything. But my garage opener was in the car. Is there a device that blocks WiFi signals as well as one that can copy my garage opener code or something ? Apparently a few other cars were rummaged through as well. If this device exists is there a way to defend against the WiFi blocking ? Thanks by HowToHack on Reddit.com WiFi blocker - Hey guys.
