This light usually refers to the vehicle's Immobiliser System. Has this light just started to come on recently? Some Nissan models normally have this light flash when you walk away from the vehicle to show that the Immobiliser is active and working correctly while you are away from the vehicle.
If this light stays on when you try to start the vehicle it usually means the security system (the immobiliser) isn't recognising the key you are using. Are you having problems starting the vehicle?
If this is something it has just started doing try this simple fix first. Change the battery in the key fob for a good quality new one. An old battery can sometimes give a weak signal which the security system cannot read correctly and assumes it's an attempt to steal the vehicle.
Is the vehicle's battery in good condition and fully charged? Have you disconnected the battery recently? Some immobiliser systems need to be reset if the battery is removed for long periods.
They are all different but many systems will work if you leave key turned to on for 5 to15 minutes or so (need good battery) and then click right to start. Bigger issue may be chip key or ignition "reader" in vehicle may have lost contact due to age.
Hello Abdul,
I had this problem and the solution is rather strange.... Change the battery in your remote key for a brand new fresh one and see if this solves the problem. Apparently, when the lithium battery is low, the central locking will continue to work but the immobiliser disarming circuit cannot decode the signal.
encrypted software dealer only to release the factory immobiliser,locked in as you changed the battery.needs dealer software to open immobiliser and they they will not do it without fitting a merc battery and entering the bar code on the factory software programme in germany via the internet ...so be prepared to lay the golden egg
