Security light stays on. automatic lights don't come on. lights don't flash when press remote lock. controls on steering wheel don't work. battery light stays on. battery and alternator are good - we checked it

The Central Timer Module (CTM, called BCM on some vehicles) supports or controls:
Automatic door lock/central locking
Battery protection
Chimes
Exterior lights (park lamps, fog lamps, headlamps)
Interior lights
Intermittent wiper control
Power lock control
Remote keyless entry (RKE)
Vehicle Theft Security System (VTSS)
Remote radio control (from steering wheel)

It covers all the problems you described except the 4WD controls. I suspect you may want to have the CTM checked, or do like I did and just replace it (used about $75-$100 on eBay). Make sure you get the part number on yours and match the number portion (not necessarily the two letter suffix) EXACTLY.
It should be located behind the kick panel to the left of the driver's feet (that's where it is on my 2003 Dakota), but may be to the right of the glove box (have to remove the glove box to get to it).

check if the fuses are already busted. fuses are located in your kick panel, just below your steering wheel

your problem is a part called a clock spring located underneath the steering wheel.best to have a shop replace it for you, special wheel puller is required to remove the steering wheel, this part carries wires for all controls and air bag that are control by the steer wheel buttons.

The steering wheel will not "lock" until you turn it about 45 degrees from center...this is normal. If your security light is flashing, there is a problem with your security system that is keeping you from starting the engine. Try this: Set the parking brake. Turn the ignition to the "RUN" position and wait about 10 minutes for the security light to stop flashing. When the light stops flashing, crank the engine without turning the key to the off position. If it starts, take the vehicle to get the security system checked. If it doesn't start, tow it. You probably need a new PassKey sensor.

Don't worry I'm sure you will get the solution of your problem, just check the link I attached
TOYOTA SIENNA 2004 2005 2006 FACTORY SERVICE REPAIR MANUAL

does this car have an aftermarket alarm system? it sounds like it does, as i dont ever recall seeing a blue flashing light in one of these cars. do you have an alarm / auto start remote control? try locking / unlocking the car several times with the remote, if it has a remote start try starting it with the remote a few times. try locking / unlocking the car with the key. good luck!

check the alarm and central locking computer on your right of the steering wheel , unlock it and reset it after 1 hour you can try again and it should be reset and the alarm will sound if its active.

As long as the light is on the airbag system is disabled.

I would suspect that your clockspring behind the steering wheel is going bad. I would have someone with a scan tool that is able to retrieve trouble codes from the airbag system check it for codes to verify this. If so then steering wheel and steering column trim would have to be removed to access the clockspring to replace it.

i read this on the subaru tech bulletin page
i had the same problem - apparently i had inadvertently put the system into "valet" mode
to get back to normal, unlock with remote - open drivers door - hold down the unlock button on your remote for 2-3 sec - the flashing light will go out and your system should be back to normal
it's too bad the manual doesn't supply information about activating and deactivating "valet" mode
good luck
