However, if you're determined to try it yourself, here's a *general* outline. Understand this is complex and you risk causing more damage:
1. Assess the Situation: Carefully examine the ignition switch. Is the broken key completely obstructing the cylinder? Is any part of the key visible? This will influence your approach.
2. Steering Wheel Lock: Make sure the steering wheel is unlocked. If the ignition cylinder is seized, the steering wheel might be locked. Gently try to wiggle the wheel while attempting to manipulate the ignition cylinder.
3. Remove the Steering Column Shroud: You'll need to access the ignition cylinder from behind. This usually involves removing parts of the steering column shroud (plastic or metal cover around the steering column). This varies depending on the exact model, so you'll need a repair manual specific to your 1981 Jeep Wagoneer to know exactly which screws or fasteners to remove.
4. Ignition Cylinder Removal: Once the shroud is removed, you should see the ignition cylinder itself. There are usually retaining clips or screws holding it in place. You'll need to remove these. *This is where things get complicated.* If there's a broken key fragment, you may need to use very small tools (like needle-nose pliers or a specialized ignition key extraction tool) to carefully remove the fragment before you can remove the cylinder.
5. Special Tools: You might need a specialized ignition cylinder removal tool. These tools often involve inserting a small rod or pick to manipulate the internal mechanisms of the ignition switch.
6. Wiring: The ignition switch has wires connected to it. Carefully disconnect them before removing the cylinder. Take pictures or make notes of how the wires are connected to avoid problems when installing the new cylinder.
Critical Safety Precautions:
* Disconnect the battery negative terminal before starting any work to prevent accidental shorts or electrical shocks.
* Work in a well-lit area. You'll need good visibility to avoid damaging the surrounding components.
* Use the right tools. Improper tools can easily cause damage.
* Be patient and methodical. Rushing can lead to mistakes.
Again, I strongly advise against attempting this yourself unless you have significant experience with automotive repair and access to the right tools. A locksmith or mechanic will likely do this much faster, safer, and more effectively. The cost of professional help is far less than the potential cost of causing additional damage to your vehicle.
