Verso 2006 won't start

Hi, I seem to have the same problem with my Corolla verso 2004. The steering lock doesn't disengage and the car won't start even though the immobiliser light stops flashing. Have you managed to get it sorted?
Thanks

***** Update**** In the end I did manage to get my problem fixed. It had nothing to do with the key. The problem was a faulty connection in the immobiliser motor that sits on the steering column, It wouldn't disengage. Our mechanic checked and repaired the motor and now the car works fine. It's a very rare fault apparently.

07 diesel car.
seems to me ,you have a 2007 toyota COROLLA verso.
with the
2.0 L 1AD-FTV I4 turbo diesel, ?
Ill quote wiki.
"The European specification Corolla Verso was available in Europe, Morocco, Kenya and South Africa."
sorry we cant get books on your car, here.(a usa forum)

you have HVAC issues. (heater is that it?)
try to say what works and dont, with heater.
do you have heat in any mode? y/n
does the fan blow? and make that normal blower sound?
if only one part of vents make heat, and not the others
that means the vent damper is failing, or controls to it are failing.
the FSM book covers HVAC, all tests. buy one.
this is USA forum so our books do not match non usa cars.
so what country are you in, ???? we cant guess that.

what to do:
check fuses first.
so got to your (DIY?) dealer buy the factory service manual
read HVAC chapter.
or get car serviced,

my guess is you have a bad damper actuator, cause unknown..
can be controls , wires or a bad damper actuator (or motor)

Start with a major tune-up, then replace the fuel filter, then verify fuel system pressure and correct any fuel delivery issues.

Have them check your fuel pump.

Despite all the fancy electronic battery testers available very few of them have the ability to detect a battery that has sulphation problems. You will probably find that if you charge the battery it's fine for a while but if you leave your hazard indicators on for about 15 - 20 mins with the engine off the battery will not have enough power to turn the engine over again.... Typical symptom of a sulphated battery - remedy, change the battery.... hope this helps.

Always have the battery tested in a situation like this.

check for proper voltage and amps being delivered by the battery first, and clean all connections, place a multimeter on the battery one leg on each post, and have someone turn the motor over, if it drops below 10 volts ,, replace the battery as its weak or has a dead cell, if it does have 11 volts, check the brushes in the starter itself and replace as necessary ,

my toyota corolla d4d 2.0 fuel filter light keeps coming on. when this happens it is my understanding that
the car may not start, it does not pick up speed and there could be a leakage of fuel. but none of this is happening everything seems fine
