The car symbol is an indication that the system has re-immobilised the engine, moving the fob closer to the ignition switch or pressing the unlock button will remobilise the engine again. Standard stuff, the exact wording on this is in your owners handbook.

It's called "passive immobiliser"... it can be disabled with dedicated tester

That's possibly because the fob was always in close proximity to the ignition/switch when the key is inserted, if it wasn't and like mine on a short length of chain, then after a short delay around 30 seconds the car key symbol would appear in the dash display... not that this is an issue for me as I'm on my way within 30 seconds, and if it was I just move the fob nearer.

Mine started doing that recently, for no apparent reason. It’s linked to leaving the car unlocked for more than a few minutes. It never used to do it, so I’ve onviously done something to change it.
