Can anyone help me...can't remove key from ignition?

I have an '06, the key is locked in the ignition because the car doesn't think it's turned off, it thinks it's in park or in gear, whoever changed the battery must have been having a bad day...
suggest you call a Toyota garage if your electrical problems don't go away when you restart the car.
BTW, the positive terminal for the battery has three electrical connections all of which can be disconnected for inspection, I wonder if one of them is loose or unconnected.

 

Try holding the POWER button down for several seconds. See if the car will turn off.

If not, you won't be able to remove the fob from the slot, until the 12V battery is disconnected and then replaced. Do you have the tools and ability to disconnect the battery yourself?

If not, you can at least remove the mechanical key from the fob so that you can lock the car.

Look at the end of the fob where it is sticking out of the slot. Note a slide on the end and move it with a finger while pulling on the key chain ring with your hand. The mechanical key will slide out of the fob.

Lock the three doors (besides the driver's door) manually. Then close the driver's door and use the mechanical key to lock the driver's door.

 

You can buy the 12V battery at your local Toyota dealer's parts department. MSRP is $139. Call ahead to see if it is in stock. You cannot buy the correct battery elsewhere because the battery terminal posts are a smaller diameter than the US standard.

You can jump the car if needed as long as you are 100% sure that you have the battery polarity correct. An error will probably short out the inverter, which will cost you $2-3K to replace.

It is not particularly hard to replace the 12V battery if you have metric sockets and open end/box wrenches available. The battery is located in the right rear of the hatch under the triangle-shaped floor cover. To open the hatch without battery power, you have to crawl into the back. Remove the folding hatch floor. Find the little rectangular panel in the black tray over the spare tire and remove the panel to find the mechanical hatch lock release.

It will be necessary to remove the traction battery vent that runs over the 12V battery, as well as the brake power supply which is the rectangular black box next to the battery.

Remove the negative battery cable where it connects to the body, as that is easier to access than the cable connector at the battery.

Don't forget the vent hose that runs down from the battery to the body. Before removing the hose, feel around to see where the hose goes into a grommet in the body.

 

*Don't* force the key out of the slot. Change the battery or jumpstart the car first.

 

Ask her if she can order parts from a dealer. I've purchased items from a parts store, and then took the paper work to a dealer to pick them up. Mechanics also buy parts from dealers at wholesale, and then mark them up to the same price as the dealer would charge you directly.

 

I would keep an eye on the battery thrrough Maintenance Mode on the MFD. Trickle charge the battery & if it holds a charge I'd leave it alone. If it doesn't then buy the battery, trickle charge it until it is full then swap it out. Toyota's replacement battery will have a 1 year/unlimited mileage warranty.

The fob is stuck in the slot because the car has determined that it needs to run to charge the battery.

There are different ways to test a battery & some are more reliable than others.

 

Some shops use a pass/fail battery tester in which the "Pass" voltage limit is too low for the Prius electronics.

You can easily test the battery yourself with no tools using this built-in procedure:

At this point I suspect that your battery is either nearly dead or not long for this world.

 

I suspect that although you charged the battery that it will fail again and quite soon. There probably is a weak cell or two in the battery so you either have to trickle charge it all the time or the the better thing is get a new battery. Winter is around the corner and it really sounds like this battery will not survive.

 

The headlights do not always automatically turn off when the car is turned off. The headlights will automatically turn off if you power down the car, and then open the driver's door. Only that combination will automatically turn off the headlights.

Opening the driver's door and then turning on the headlights will result in a dead battery. Likewise leaving the lights on and exiting through another door.
