Cant remove key

If you're in a pinch you can disconnect the ignition coil to shut your vehicle down...DON"T disconnect the battery as this can cause damage.
From there you'll be able to check the key tumbler/ignition for issues within the steering column. Good luck!

It is hard to give a definite answer because I don't know which and how many wires were damaged...Anti theft can be a real HEADACHE.....You can begin by disconnecting battery cables..Use your VIN number for parts,Get new ignition with a programmed factory key from dealer only.....They probably blew certain fuses and or relays when this happened...Or maybe not..Install new ignition connect battery cables..,turn switch on just to check for bad fuses and relays...Disconnect battery again...replace any fuses blown...Connect battery again...( Each time you disconnect battery it resets the computer system and should clear anti theft codes..)..make sure all doors are unlocked by using door remote key fob....Now see if vehicle will crank..If all is done correctly it should start...However I don't know how much damage was done.....It may possibly be too much work to totally disengage anti theft....You could start with removing all fuses and relays related to anti theft but disconnect battery before...I DO NOT RECOMMEND trying to disable the theft system.....You may create more headaches that you want.......Begin by trying what I described just to be safe...!!....

Hello: Make sure key is off and out of ignition. Remove back seat lower cushion. Disconnect negative (black) cable first. Disconnect positive (red) cable next. Remove vent hoses. Remove 13mm bolt back lower side of battery, remove hold down plate. Remove battery. It is a big HEAVY battery so be careful not to drop it. Best to wear gloves so you don't cut/scrape your hands. Re-install new battery in reverse of removal, ie cables Positive (red) first then negative (black).

DONT REMOVE POSITIVE BATTERY CABLE FIRST YOU WILL SHORT OUT THE PCM AND THE ALTERNATOR.IN CASE YOU CANT TURN OFF CAR ONE TIME DEAL DISCONNECT NEGATIVE BATTERY FIRST. BUT FIRST TURN OFF RADIO BEFORE REMOVING BATTERY CABLE.YOU NEED TO FIX IGNITION SWITCH LOCK CYLINDER DONT KEEP DISCONNECTING BATTERY WHILE ENGINE RUNNING BECAUSE YOU WILL DAMAGE PCM.AND SHORT OUT ALTERNATOR VOLTAGE REGULATOR.

SINCE CAR WONT CRANK. NOW IS THE TIME TO REPLACE THE IGNITION SWITCH KEY LOCK CYLINDER ITS BROKEN THAT WHY THE CAR KEYS WOULDNT TURN OFF CAR.DISCONNECTING BATTERY CABLES WITH CAR RUNNIMG WILL.SHORT OUT ALTERNATOR AND PCM.IF IN CASE YOU HAD TO REMOVE BATTERY CABLE REMOVE THE GROUND NEGATIVE CABLE FIRST.MAKE SURE ALL ELECTRICAL COMPONENTS OFF LIKE RADIO. AC SYSTEM OFF.THIS WILL PREVENT LARGE ELECTRICAL ARC FROM BATTERY THIS IS ONE TIME PROCEDURE IN CASE ENGINE WONT SHUT OFF ITS A GAMBLE BECAUSE IT WILL TAKE OUT ALTERNATOR AND PCM.REPLACE THE SWITCH AND KEY LOCK CYLINDER DONT KEEP STARTING CAR BY DISCONNECTING THE BATTERY CABLE YOU WILL DAMAGE IGNITION ELECTRICAL SYSTEM.

Sounds Like the Starter RELAY is Bad After Exhausting All other Test, Go For The RELAY
A SURE-SHOT way Is to Jumper Wire From Battery to (STARTER SIDE) of Relay if starter Works then Its the Starter Relay if NOT>>Then Its the STARTER<) Relay Instruction Below. STARTER Instructions Very Bottom
