Turn Key Fob off

[PGCairo]

Is there a way to stop the key fob from broadcasting a signal - Stinger GT

Removing the battery will do the job.
But I guess that's not what you wanted to read.
The only way is:
Put the key in a Faraday pouch.
Be aware that those are a little bit chunky.
The pouch must be sealed hermetically to prevent the key from a relay- (repeater) attack.
If you just want to prevent some bad guys stealing your ride from the driveway
then use a sealed tin box where you're storing the key.
(Faraday cage)

A third way would be that you're purchasing an additional key fob and a relay box
and interrupt the power supply to the keyless-go module in the car.
Be aware that this must have a rolling code encryption at least to prevent criminals from cloning that key.
All those cheap China crap fobs and relay boxes are totally useless because they're super easy to clone.
(As same as the most motorized garage doors with a remote.)
As a hint: Forget all those relay boxes who can be "trained" with any random key fob.
In your case the key fob and the receiver electronic must be matched from the factory.
Usually those have about 50000 rolling codes before the code list starts from new.

Hey KDM-W - That might be an idea for the store
