And take the distributor rotor arm off - oh I forgot we don't have those simple mechanical things anymore Laughing


I suppose we need to store the car key fobs in a metal biscuit tin or similar. Jules

I must be miles behind latest tech, a quick net search finds there are many RFID signal shielding pouches available - seems same technology/pouch prevents tracking of cellphones Shocked

There are two solutions either put your keys in a tin box like a biscuit tin (Faraday Cage) or put your car in one. Very Happy

PS best technique years ago was to swap two plug leads over, even if they hot wired the ignition system the engine wouldn't run properly and a thief would assume something was wrong with it. 3 x FL1 2 manual + 1 auto

What about adding a secret fuel pump switch or something similar.

On my old BMW 3 series it was possible to break the drivers quarter light glass and slide a cable down to the OBD socket, without the internal sensor activating the alarm, and then code a blank key in about 2 mins to then unlock and drive off with the car once the owner had unwittingly replaced the broken glass. One method to prevent was to physically move the OBD socket to somewhere else hidden under the dash and then add an extension socket to a secret place. Jules

Unfortunately, this doesn’t work. The “tin” needs to be made of aluminium, or completely lined in aluminium foil.

Sorry but it just needs to be a conductor, I have seen screened rooms in electronics labs which are copper lined.

Wrong, Im afraid, about the metal - any conductor will do but you are correct in that a solid "cage" is better at attenuation than a mesh one.

https://en.wikipedia.org/wiki/Faraday_cage

"A common misconception is that a Faraday cage provides full blockage or attenuation; this is not true. The reception or transmission of radio waves, a form of electromagnetic radiation, to or from an antenna within a Faraday cage is heavily attenuated or blocked by the cage, however, a Faraday cage has varied attenuation depending on wave form, frequency or distance from receiver/transmitter, and receiver/transmitter power. Near-field high-powered frequency transmissions like HF RFID are more likely to penetrate. Solid cages generally provide better attenuation than mesh cages." Jules
