Is It the Ignition Switch or the Lock Cylinder?
Many owners confuse the ignition switch with the ignition lock cylinder. On your 1987 R10, they are two different parts. The lock cylinder is where you insert the key. The ignition switch is an electrical box located further down the steering column that the lock cylinder controls with a long rod. If your key is physically stuck or won't turn, the problem is likely the lock cylinder. 🎬 Watch this video to learn how to replace the lock cylinder. If the key turns but the truck has electrical problems or won't start, the ignition switch is a common suspect.
Common Symptoms of a Failing Ignition Switch
An ignition switch wears out over time. The electrical contacts inside get burnt or lose connection, leading to frustrating and intermittent issues. Watch for these signs:
- Engine Won't Crank: You turn the key to 'Start' and nothing happens—no click, no crank. You may have to 🎬 See how a new ignition switch fixes common no-start problems. jiggle the key or try turning it multiple times before it finally engages.
- Stalling While Driving: The engine may suddenly shut off while you are driving. This happens when the switch loses connection, cutting power to the ignition system. This can be a serious safety issue.
- Intermittent Electrical Problems: Your dashboard lights might flicker, or accessories like the radio and heater fan may cut in and out. This happens because the switch isn't providing steady power to the accessory circuits.
- Starts then Immediately Stalls: The engine may fire up for a second and then immediately die. This can indicate the switch is providing power to the 'Start' circuit but failing to power the 'Run' circuit.

Frequently Asked Questions
How difficult is it to replace the ignition switch myself?
It is a manageable DIY task for most home mechanics and does not require special tools. The main steps are removing the lower dash panels and unbolting the steering column to let it drop down, providing access to the switch on top of the column. The replacement itself is just two screws and the electrical connectors. Estimated time is 1-2 hours.
Is the 1987 R10 ignition switch part of the big GM recall?
No. The widely publicized GM ignition switch recalls involved vehicles from 2003-2007, like the Chevy Cobalt and Saturn Ion. The 1987 Chevrolet R10 is not affected by those recalls, and there are no specific recalls for its ignition switch.
What's the difference between the ignition switch and the lock cylinder?
The lock cylinder is the mechanical part your key goes into. The ignition switch is the electrical part that sends power to the truck's systems. They are connected by an actuator rod inside the steering column. If your key is hard to turn or gets stuck, the lock cylinder is the likely problem. If the key turns fine but you have electrical issues, the switch is the more likely culprit.
What if I replace the switch and the truck still won't start?
If a new switch doesn't solve the problem, check other related components. The issue could be a dead battery, a bad starter, or a blown fusible link at the starter. It's also possible the actuator rod that connects the lock cylinder to the switch is broken or misaligned.
