It’s amazing to test this yourself. Hold down the button of a garage door opener and try to use your vehicle lock / unlock button. It doesn’t work. Simple as that. The signal from the garden variety garage door opener blocks the signal of most (all?) vehicle remotes.
Smart criminals are increasingly using this to stop owners locking their doors and stealing goodies from cars. This seems to be getting worse in Cape Town CBD at the moment.
So why I am talking about verification?
Well, to prevent the problem requires either a high tech revamp of the vehicle remote industry, or for owners to actually observe or check that their doors are in fact locked. Listening for the clack, watching the hazard lights flash or even physically testing that the door is locked.
These methods work perfectly and are only the tiniest bit of extra effort.
Relying on models to simply give the right answer without checking that it makes sense is likely to get your credibility burgled. Form high level initial expectations, hypothesize plausible outcomes, check sensitivity to assumptions, reproduce initial results and run step-wise through individual changes, get a second opinion and fresh eyes.
This all takes a little time in the short term and saves everything in the long term.
