keyless entry security hack

Keys/keyless only keep honest people out.

 

aluminum foil does the trick well

 

Look at the dateline. That is old news, 2 years ago. See previous discussion threads, here are some of them:

Might want to store your PiP fobs in a metal container | PriusChat

For the vast majority of us, this threat remains theoretical, not a significant part of reality. The threat has increased a bit since then, according to subsequent reports, but this still doesn't seem to be a common problem.

BTW, don't keep the fob in the freezer or refrigerator. The repeated thaw and warmup cycles predispose the internal electronics to condensation and other moisture problems.

 

Double wrap the fob in aluminium foil, single layer is not enough. Try walking up to the car and see if it unlocks, if it unlocks try another layer until it will not unlock. Special wireless pouches, often are rubbish, get a recommended one that has been tested by one of the magazines. Otherwise use your Christmas biscuit tin and turkey foil.

 

Or you could put the key into battery-saving mode. When in this mode it stops receiving radio waves.

 

rather have them open the door with my key then break the window... if they want to get in they're going to get in. side windows can be broken easily and with little noise (just cover them with sticky paper and use a $10 fire/rescue windows punch tool), the tacky paper keeps the glass from flying everywhere and "tinkling"
