I have 01 montero sport and the key is stuck in the ignition on accessory what could be the problem

Disconnect the battery: Before beginning any work on the electrical system of your vehicle, disconnect the battery to prevent accidental shocks or short circuits.
Remove the steering column cover: The ignition switch is located on the steering column, so you'll need to remove the cover to access it. Depending on the exact model and trim level of your Montero Sport, the cover may be held in place with screws or clips.
Remove the ignition switch: Once you have access to the ignition switch, you'll need to remove it from the steering column. This may involve removing any retaining screws or clips that are holding it in place, as well as disconnecting any electrical connectors.
Install the new ignition switch: Install the new ignition switch in the reverse order of the previous steps, making sure that it is securely fastened to the steering column and that all electrical connections are properly connected.
Test the new ignition switch: Once the new ignition switch is installed, reconnect the battery and test the switch to make sure that it is working properly. Insert the new key and try to start the engine. If the engine starts and the key can be turned smoothly, you've successfully replaced the ignition switch.
It's worth noting that depending on the specific make and model of your Montero Sport, the exact steps for replacing the ignition switch may vary slightly

Question edited for clarity.

Try an auto electrician. They have better scan tool computers and there may be an underlying issue with ECM, BCM or the Security Module.

Sounds like you have a bad ignition switch. It's the little box under your steering column with all the wires running to it.

how to reset key fob after changing battery on a mitsubishi carisma

Well the radio code is an anti-theft issue. you have to take it to the dealership and they get your VIN number and they will retrieve the serial number to your radio. With that they can look up your code. It will cost at least $75 dollars.

Make sure they connect it back up correctly because then if you live in climates that reach under 20 degrees your radio will shut off. or when hit a bump in the winter your radio will shut off and you have to enter the code everytime it goes off.

I have an '01 montero sport XLS. Battery died and I had to experience this the hard way.
