Key on my 2011 4/4 would occasionally fail. Usually removing it & holding it at arms length then trying again seemed to work. This was from new. Anyway about 4 months ago used my 2nd key & touch wood it has worked every time. Not sure what powers the keys or could their sensitivity be different.

Hold it to your head when you use it. Clarkson trick, never needed to try it.

It's not a zapper Bob, just a simple key with a transducer in the plastic part. No batteries either!

The Clarkson trick does work with zappers though. I've tried it a few times.....

They are ultra sonic & I guess the head acts as an amplifier like the head of a whale does.

sorry Dave, don't understand is there nothing to internally power the key. Sounds like magic. Can't see any way of getting into the key. PS luckily this car came with four keys.

Google it Ray. The coil around the steering lock barrel induces a current in the chip and asks the chip to identify itself. The chip provides a code which disarms the immobiliser.

The immobiliser remains off until the key is removed and after about twenty seconds it re-arms.

Fancier chips also receive a new code each time they are used but I don't think this happens with the Ford system.

Anyway better news. I spent the morning messing with the cowl. The original key works every time with the cowl removed and the sensor ring closer.

I've re-wrapped the lock barrel, this time with leather. I've also ground away the plastic from the inside of the cowl around the lock hole to get the sensor ring as close to the key as possible. It took three fits to get an acceptable look but its back on. Since then its worked every time. Only time will tell if that's it. thumbs

Dave, you mention Ford as the OEM for the immobiliser, (& I assume ignition lock), does that mean with the Land Rover indicator stalks we still have a mix of suppliers ?
