I have an 'S' type Jaguar 51 plate with mileage only 50,000. I left the side lights on whilst the car was parked for 4 hours & there was no battery power left. The electrics have gone haywire and I struggled to get in the car even using the key manually as the doors wouldn't open. I eventually got in and used jump leads from another car which had it's engine switched off(in accordance with the manual). The Jaguar started straightaway but cut out immediately with the alarm going off. I tried it 3 times, each time the engine started immediately but then cut out. Is there some way of overriding the vehicles alarm?

Hello and welcome to justanswer.comThis problem could be the result of low voltage. I recommend we put a good long charge on the battery then unlock the vehicle again with the key to disarm the security. You can also disconnect the negative battery cable to reset the system but make sure you have the radio security code.
I have had to leave the car in a Golf club car park overnight. I have no means of charging up the battery. The booster car's battery was fully charged so why did the Jaguar's alarm come on & cut out the engine?
Ok maybe we can try removing the battery and taking it to your local parts store who can charge it. Just make sure you do not fully close the trunk with the battery removed. The body/security modules may have spiked due to the loss of battery voltage.
You haven't answered the question. The booster battery is providing the power to start the engine but the alarm is overriding it.
I am thinking that when the battery went flat the module became corrupt. It may need to be reset/immobilized with a Jag factory tool but I would recommend we disconnect the battery to reset it then make sure we have a fully charged battery.
