All those codes suggest chip and/or transponder issues, sod all to do with key fob battery ::)

If the remote locks/unlocks car, and led on key doesn't flash when button held down then all is well with battery :y

Any work done which might have disturbed steering column shrouds?

The fob battery has no impact whatsoever on the ability to start, as the fob plays no part in the immobiliser.

If the EML is *FLASHING* when trying to start, that's immobiliser. If not, go back to measuring the voltage at the solenoid ;)

Sod it, just clutching at straws lads hoping it was going to be a cheap and easy fix :(

I know the battery is fine now, I took the key apart and got a meter on the battery. Its 3v peaking at 3.1 so the battery is definitely fine.

I'll check the voltage on the solenoid in the morning and report back. Hopefully that should give me a better idea of whats going on.............. ::)

Evening all :)

Just to let you know it turned out to be the starter motor. Checked across the solenoid while my Lad turned the key. No problems that end. Gave the starter a cluck with a wrench while turning the key and hey presto she fired up :y

Strange though as every starter motor ive ever had fail has made all sorts of noises when stuck apart from this one. ???

At least you know, and diagnosed it correctly.

It wasn't really going to be anything else though :)

Indeed TB, satisfying to confirm the problem but totally thrown by the lack of noise from the starter.

Now just baffled by the codes the pedal test threw up yesterday but we'll worry about that later :D

Anyway, thanks everyone for all your once more. Its very much appreciated :y

I wouldn't worry about those codes, it may mean you need a new battery. I had all those codes once on my 2.2 .... when I kept flattening the battery trying to start the thing....whilst trying to discover why it wouldn't start.....it turned out to be the fuel pump at fault.....but the low battery voltage seemed to cause the ecu to through out immobiliser 'red herrings'  :y

That is because the solenoid is dead that is attached to the starter  :y
