So how did you fix it? New key?When I had issues with my keys, the car would crank but not fire up. The immobiliser just tells the ecu not to inject fuel. The ignition switch still does the starter crank.
theres an option to 'reset' the key so you can reprogram it back to the car againLast fault was key blocked which was the key completely disabled by a unit somewhere, had to fall back on the spare key. I can't even programme this key back in now but it may be because there were too many failed attempts at starting the car. Should only need a new chip in that though.
If you have a diagnostic tool you should be able to read live data off the steering column which tells you if a key is valid etc. I had no live data off the immobiliser itself. But if you put a key in and no motor whine, the column is your best bet.
Oh wow, very interesting, dead as in dead battery?I thought I'd quickly try something for you. Went out to the car, tried the dead key which was still in the glove box, checked error codes on the ecu, P1602
I'm using SDD (TOPIx)Not seen that on any of my diagnostic stuff. What are you using?
what year is it? the youtube method only works on the early onesSO I'm thinking, new battery in the key.. then follow the re-syncing procedure on YouTube....

Interesting, but then I would need to reprogram the ECU to the car ? Would it not be easier to just reprogram the key? … also weirdly the steering wheel lock doesn’t seem to ever be on… can turn it whether car is on or off etcIf you're happy ith spanners, a replacement ecu with immobiliser disabled is £180, unplug the steering lock with ignition on, join 2 wires on the immobiliser and remove a solenoid on the ignition barrel. All can be done in 30 minutes. This completely removes the immobiliser stuff meaning easier to steal but as a last ditch effort........
Quick question though, does your steering column release with a whirring noise when you put the key in the ignition and lock with the same noise when you remove it?
Should still make a motoring whirring noise even if the lock hasn't engaged.Interesting, but then I would need to reprogram the ECU to the car ?
