I can not remove the KEY from the ignition tumbler

To replace the ignition tumbler in a 1975 Dodge Sportsman RV, you will need to follow these steps:

1. Remove the steering column cover: Start by removing the screws or bolts that hold the steering column cover in place. Once the cover is removed, you should be able to access the ignition switch and tumbler.
2. Disconnect the electrical connections: There should be two electrical connections that attach to the ignition switch. Disconnect these before attempting to remove the tumbler.
3. Remove the retaining screw: Use a screwdriver to remove the retaining screw that holds the tumbler in place.
4. Remove the tumbler: After removing the screw, the tumbler should slide out of the ignition switch.
5. Install the new tumbler: Insert the new tumbler into the ignition switch, making sure it is securely in place.
6. Reinstall the retaining screw: Use the screwdriver to reinstall the retaining screw.
7. Reconnect the electrical connections: Reconnect the two electrical connections that you disconnected in step 2.
8. Replace the steering column cover: Once everything is back in place, replace the steering column cover and secure it with the screws or bolts.
9. Test the new tumbler: Finally, test the new tumbler to make sure it is working properly and that the RV starts and runs smoothly.

I suggest a locksmith be called in to remove the barrel
he will be able to supply a new barrel and cut the key to suit what you have and set the tumblers to the new key

If the key does not turn at all in the ignition tumbler then your going to need to drill a hole in the side of the steering lock in order to manually release the steering lock and remove it complete with the ignition tumbler attached. If you get a new steering lock you can examine it to see exactly where to drill the hole and how to manually release it. If the key does turn at least to position 1 then all you need is the removal pins that slide into the small holes around the face of the tumbler. If there are no holes then once the key is in position 1 all you have to do is turn the tumbler housing to the left until is unscrews. Let me know if you need any further assistance on the removal if the key is stuck.

Look on the bottom of the housing, use a high speed 3/16 drill bit.

Physically removing a piece of an ignition key from the tumbler is practically impossible. The tumbler is filled with spring loaded tabs which raise and lower against EVERY notch on a key. That resistance will fight your every motion as you try to back the key remnant out. As one tab releases, the next in line raises into the vacancy just created. GM, even with the "fob"/ chip installed in most of their keys, also put greater anti-theft detail into their ignition tumblers. IF this is an ignition lock that has a chip sensor, the practical repair is a complete key/tumbler replacement. This isn't a DIY repair. It will involve removing the steering wheel and column covers, air bag, AND re-coding the vehicle computer to accept and recognize the new key/chip code. The re-coding CAN be done at home. Immediately after the new tumbler is installed, leaving the ignition in the "run" position for 1 hour, will re-code the antitheft in the computer.

look at the steering column below the ign lock and tumbler there should be a small hole turn key to on pos and push a small rod up the holethis then should release the lock and tumbler,no hole then wheel and coumn has to be stripped to get to lock retainer

ok some where on the tumbler there will be a very small pin hole you will have to put the key in turn it forward one click then take something that will fit in the pin hole and push in and pull out on the key this should remove the tumbler then follow the directions on the new tumbler to put it in

Most often the lack of spring back is not the key and tumbler set itself. There is no spring back in the tumbler but rather the internal area of the column- you can determine this by cylinder removal if you know how to remove. A 96 is most often what they consider a 10 cut side bar ignition. by diconnecting your battery and removing some shroud around the ignition. You will need to turn the key to crank postion and hold it their in order to depress the retainer that holds the cylinder in place, located top ignition.( Retainer small hole area)
While depressing retainer pull cylinder out -and you will have lock in hand for you to examine.

Take it to a locksmith. You don't want to risk pulling it down yourself especially where the immobiliser harness is concerned, in addition Honda tumblers are really hard to source, the defectives ones will have to be removed. You need an experienced locksmith to do this.

Place key into ignition, use a paper clip and press the tiny hole on the switch. Turn the key back towards ACC position and pull the cylinder right out. Reverse procedure to install.
