Dodge Charger Ignition Lock Cylinder Guide for 1966-1979 Models
Having trouble with a stuck key or a no-start condition in your classic Charger? Your ignition lock cylinder is a likely culprit.
- Failure is almost always due to simple mechanical wear from years of use.
- Symptoms include a sticky key, difficulty turning the ignition, or a complete failure to start.
- Replacement is a simple, DIY-friendly job that can be done in about an hour.
- Aftermarket parts from brands like Standard Ignition and Dorman are the most common and cost-effective solution.
Signs of a Failing Ignition Lock Cylinder
An ignition lock cylinder doesn't usually fail suddenly. It gives you warning signs. Because it's a mechanical part that you use every time you drive, it wears down from repeated use. If you notice any of these symptoms, it's time to think about a replacement before you get stranded.
- Key is Hard to Insert or Remove: If you feel like you have to jiggle or force the key to get it in or out, the tumblers inside the cylinder are likely worn or misaligned. Before blaming the cylinder, try a spare key to make sure your primary key isn't just worn out.
- Key Won't Turn: This is a classic sign of failure. You can get the key in, but it refuses to turn to the 'On' or 'Start' position. This happens when the internal pins and springs are worn or broken, and they no longer line up correctly with the key.
- Car Won't Start: You might turn the key and hear a click, or nothing at all. While this can also be a symptom of a bad starter or battery, if it's paired with a loose or sticky key, the lock cylinder is a strong possibility. The cylinder isn't making the proper contact to activate the ignition switch.
- Engine Starts and Then Stalls: In some Mopar models, a faulty lock cylinder can cause the engine to start but then immediately die. This can happen if the cylinder doesn't hold the correct position after starting.
Choosing the Right Aftermarket Ignition Lock Cylinder
For a classic vehicle like the 1966-1979 Charger, finding a "New Old Stock" (NOS) OEM part is nearly impossible and very expensive. Used original parts are an option, but you risk inheriting a part that is already 40+ years old. For this reason, new aftermarket parts are the most practical and popular choice for most owners. They are affordable, widely available, and engineered to fit.
The two main brands you will encounter are Standard Ignition (SMP) and Dorman.
- Standard Ignition (Standard Motor Products): Often considered a higher-tier aftermarket brand, Standard parts are known for their quality control and precise fitment, which is crucial for classic car parts. Many professional mechanics and restoration shops prefer Standard for ignition components due to their reputation for reliability.
- Dorman: Dorman is a well-known brand that produces a huge variety of replacement parts. They are generally more budget-friendly and are a solid choice for a daily driver or a budget-conscious repair. While their quality is generally good, some classic car enthusiasts note that the fit and finish might not be as exact as a Standard part.

Frequently Asked Questions
Can I replace the ignition lock cylinder myself?
Yes, this is a very DIY-friendly job for most 1966-1979 Chargers. The process typically involves removing the steering wheel and using a small screwdriver or punch to depress a retaining pin that holds the cylinder in place. The entire job can usually be done in under an hour with basic tools.
Will my original keys work with the new lock cylinder?
No. The new aftermarket lock cylinder will come with its own set of new keys. If you want to have one key for your doors, ignition, and trunk, you will need to buy a complete matched lock set.
What's 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 part behind it that the cylinder activates. The cylinder is like a light switch handle, and the ignition switch is the electrical box in the wall. Sometimes they are replaced as a single assembly, but often they are separate parts.
Are there any recalls for the 1966-1979 Charger ignition lock cylinder?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls for the ignition lock cylinder on 1966-1979 Dodge Chargers. Recalls for ignition switches on much newer Charger models (from 2008) do exist, but these do not apply to the classic 1966-1979 generation.
