Iirc, HS drove a Lexus, which happens to be one of the favoured cars to steal.
Thinking the perp/s could have used similar methods to enter the car and house and a type of protective clothing worn. fwiw, imo.
For example..

"Thieves boosting signal from key fobs inside your home to steal vehicles, automotive security specialist says

"According to Markham automotive security specialist Jeff Bates, owner of Lockdown Security, wireless key fobs have a role to play in many recent car thefts, with thieves intercepting and rerouting their signals — even from inside homes — to open and steal cars."
"Bates said the spike is so great, a local Toronto car dealership selling new Lexus vehicles asked his company to install tracking systems on all high-end SUVs because so many of their vehicles are being stolen."
"Key fobs are constantly broadcasting a signal that communicates with a specific vehicle, he said, and when it comes into a close enough range, the vehicle will open and start."
The thief will bring a device close to the home's door, close to where most keys are sitting, to boost the fob's signal.
They leave another device near the vehicle, which receives the signal and opens the car."
