Reset immobiliser turns over good no start

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.

replacing the battery energises the immobiliser so it will not allow the engine tom start. Try using a scanner to reset the immobiliser

ive had this problem with another make of car before, the immobiliser was stuck on stopping the car from starting, reset the immobiliser by disconnecting the battery for a couple minutes and reconnecting it. good luck.

the immobiliser is probably the cause of this . first try and reset the immobiliser by using a code reader to reset the CPU

Hi, Sounds like the immobiliser isn't de-activating. The system will prime when the ignition is turned on and the car will start but then the immobiliser will cut the fuel after 2-3 seconds. Are there any warning lights or led lights staying on. If you have a spare key and haven't tried it then start there first. If you do and neither key works then it could be a number of things including the pick up ring around the ignition barrel but you would need to get the car checked out proffesionally before you start replacing parts. Good luck, Jon.

Immobilisers may intercept one of three circuits; typically the low-voltage ignition circuit and the fuel pump circuit. Some may also intercept the low-current starter motor circuit from the key switch to the relay. The Immobilisers can be set to intercept these circuits IF you use a key that has been copied or someone tried to start the car with the key for another car. Once activated, most of the time they are on a timer, meaning they will reset in 10 to 20 minutes. You can try and reset yours by disconnecting the battery, remove both cables and touch the two cables together for ten minutes. Now if you have a radio that needs codes to reset it be sure you have the codes before disconnecting the battery. Some Immobilisers use a magnetic switch to turn off the car. buy disconnecting the battery and touching the cables together you will kill the magnetic field and reset it. Hope this helps fixya up.

The mechanic that you talked to was exactly right

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/sean_54c3a3dc48a7773c

check all the fuses - attempted hotwiring will have blown a few. likely you will need to do more than plug everything back in to start this bird again - immobiliser will not let this car start, it "thinks" the car is still trying to be stolen more than likely and wont start without a reset immobiliser... i'm no expert on modern security devices tho so dont take my word for it but the dealer is probably the only way to reset it. or a good garage who know plenty about ECU's and immobilisers

you have an override toggle switch hidden somewhere under dash youll have to search for it.

Hi
Had a similar problem with my x type 2.5 petrol, only had the car 1 day went to start it nothing happend all the lights came up on the dash but the engine wouldn't start and the immobiliser light stayed on. Spoke to Jaguar they had no idea and I couldn't get it to them. After disconnecting the battery trying to reset the immobiliser phoned and auto locksmith they came out and discovered the end of the key with the blade had lost it's coding and the immobiliser was not disarming, they reprogrammed the key and the car started no problem. As far as i know there is no way past the immobiliser. Hope this helps.
