Is Your Ignition Lock Cylinder Failing?

Key Symptoms of a Bad Ignition Lock Cylinder
- Key is Hard to Turn: 🎬 See how to replace the cylinder when your key won't turn. You have to jiggle or wiggle the key to get it to turn to the 'run' or 'start' position.
- Key Gets Stuck: The key won't come out of the ignition, or it gets stuck in one position.
- Truck Won't Start: The key turns, but nothing happens, or it only clicks. A worn cylinder may not properly engage the electronic ignition switch behind it.
- Steering Wheel Remains Locked: You can't turn the steering wheel even with the key inserted because the cylinder isn't disengaging the lock.

The difficulty can vary slightly between tilt and non-tilt steering columns. Some procedures may require a steering wheel puller if you cannot access the release mechanism easily.
What is the difference between the ignition lock cylinder and the ignition switch?
The lock cylinder is the mechanical part your key goes into. The ignition switch is the electronic component behind it that the lock cylinder turns. If your key won't turn, the problem is the lock cylinder. If the key turns fine but you have no power, the problem is more likely the ignition switch.
Will my original keys work with the new lock cylinder?
No, a new aftermarket lock cylinder comes with its own set of keys. You will need to use the new key for the ignition and your old key for the doors. Alternatively, you can take the new cylinder to a locksmith before installation and have them re-key it to match your original keys.
Are there any recalls on the ignition for my K2500?
Searches for the 1994-2000 GMC K2500 did not show any specific recalls for the ignition lock cylinder itself. There were major GM recalls for ignition switches in other, newer vehicles that could lose power while driving, but these do not apply to the GMT400 platform trucks like your K2500.
