It seems I've found a simple and very inexpensive solution to the problem of abnormally fast discharging batteries in Grecale due to their close placement to the parked vehicle: get one of the many Faraday signal-blocking bags/pouches for FOBs, car keys and cell phones available online for as low as $8-$30. Most are well-made and properly sized for Grecale keys. I think Maserati should look into providing such signal blocking storage cases for its cars.
Hi,
Yes anybody with a keyless entry vehicle should be using a faraday pouch unless they want their vehicle stolen by thieves using a relay attack. (check on YouTube you will be shocked how common this is with any make of vehicle)
Maserati use to have an option in the car menu system to disable keyless entry, but removed it due to the possibility of stupid drivers just wearing the keyless wrist band and turning keyless entry of in the menu !?!?!? and then exiting the car and then cant get back in when it locks !!!!
I have pushed Maserati to put the feature back in as I believe its the drivers responsibility not the manufacturer top enable/disable this type of function, also if you have the Maserati mobile app AND get locked out of the car like above - then you can unlock the car with the app, so no issues !!
Maserati's response is that they wont be bringing this keyless entry disable feature back - which is a shame, it wont be long before insurance companies start increasing premiums if you have this feature enabled and are NOT using a faraday pouch/box..
Another simple feature they could have done is to make the key fob go to sleep after say 10 mins of zero movement (simple to do) and wake when moved, this would stop the fob sending signals to the car - removing the potential. theft and battery drain and no need for a faraday pouch.
There is a 3rd party product in the USA that fits in the key fob between the battery and pickup and works just like above - after a zero movement period, the device cuts the power in the fob between the battery and pickup, when the fob is moved, it take the circuit again and all works.
