Technical Suddenly its completely dead

[EndlessNites]

Hi,

I started my car up this morning no problems at all, drove for about 10mins, parked the car and tried using the key remote to lock the car but it wouldn't work so I locked it manually (the light still flashed on the key and it opened fine when originally I set off) I thought nothing of it thinking I probably needed a new key battery. I came back to the car an hour later and it still wouldn't open with the remote and when I went in to start the car it was completely dead, no sound or dash lights at all. Someone told me I'd immobilised it and probably need a new battery in the key. I replaced the battery and its had no effect.

The car battery is new as I had a flat battery a month ago, even then the dash lights still came on.

Can anyone tell me what's wrong?

Thanks,
Sal

Is it possible your alternator has gone ?

That would also account for the battery you had to replace a month earlier.

easy enough to check - if battery is gone beyond the power needed to power up an ecu: try switching on the radio (and hazard lights) if all works ok - turn the key (all will die if it is the battery). Alternator will show up as error on the dash.. it is (marginally)possible that you have a bad contact on a battery terminal - check that + fuses (if that is not the case you are in for more trouble).Keys do fail, so do immobiliser chip antenna (use search) – but no lights at all on the dash tells me it is not the key nor is it power (central locking will not work at all). Could be key (ignition) barrel failure (simplest solution)

Thanks, radio/hazards didn't work, I'm going back over there to check the battery connections etc now and calling someone out to sort it.

The shop I got the battery from didn't have the car in their book so took a tape measure out to check the size, I've heard it's important to get the correct battery for Stilos so I don't know if thats done something. I chose the higher power one of the two they offered me.

Its sorted, the lead had come off the battery and if I'd got any tools in the car at the time I could have taken the battery cover off to check it then & there.. but still, panic over.

Thanks for the replies.
