Car won't start, turn the key and nothing happens.

I had that happen a couple of times. Once it was as simple as the battery. The next time I wasn't so lucky as it was the fuel pump. How this helps

Replace the battery in the remote.

-do you use the right key? (thick brown/black colored) after aou turn the key on, does a light go on on the dashboard?
- seems to be an issue with the lock code of the key (wrong key)
then the engine immobiliser does not allow to start..

Sounds like a loose connection, check your battery terminals are tight. if you have to boost or jump start the car check your battery condition and alternator output. Check the terminal on the starter motor and solenoid. Finally check the starter

your car have a soon roof ? check if safe close

This would appear to be a immobiliser fault? Try a manual start - do not use fob, open door with key and immediately put the key in ignition and start the car. Using this method - when you open the door you will hear a chime this is counting down to starting the alarm. This method can sometimes get around a fob/immobiliser fault. If this makes no difference then you need to get the car checked at a Jaguar dealers for the security system. - good luck.

its an electrical problem so u r advised to meet ur mechanic

Hi .
unlikely to be immobiliser fault ,so check basics,try a set of jump leads or check battery voltage above 12.5,if the clicking is coming from the starter motor with a fully charged battery then suspect starter motor failure.

Hi

I suspect the cold weather was the fundamental problem, usually emanating from a battery voltage drop, and kicking in the on board computer gremlins.

Jags just don't like it !

Lets hope the weather improves for you there in UK, and your little gremlin does not return.

Good Luck !

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.
