Frequently Asked Questions (FAQ)
Do I need to program the new key?
No. The 1993-2000 Chevrolet C2500 does not use a transponder or 'chip' key security system like newer vehicles. The replacement is a simple mechanical swap, and the new keys included with the cylinder will work immediately without any programming.
Can I just replace the cylinder, or do I need the whole ignition switch?
You can replace just the lock cylinder. The ignition switch is a separate electronic part located further down the steering column that the lock cylinder activates. If your only problem is a sticky or non-turning key, the lock cylinder is almost always the cause. If you have widespread electrical issues, the switch itself might be the problem.
🎬 Watch: How to replace the ignition switch if electrical issues persist.Will the new key work in my doors?
No, the new key will only work in the ignition. You will have to carry two keys: the new one for the ignition and your original key for the doors and tailgate. A locksmith can re-key the new ignition cylinder to match your original key, but this adds extra cost.
What if my key is stuck and won't turn to the 'On' position for removal?
To remove the cylinder, the key must be turned to the 'On' or 'Run' position to access the release pin. If the key is completely stuck, try wiggling the steering wheel firmly while attempting to turn the key. Sometimes, spraying a dry graphite lubricant into the lock can help free up stuck tumblers. If it still won't turn, the job becomes more difficult and may require a locksmith or drilling out the cylinder.
