Dodge D150 Ignition Lock Cylinder Guide for 1977-1985 Models
Having trouble with your key not turning or getting stuck? Your ignition lock cylinder is likely the culprit.
- Failure is almost always due to mechanical wear, showing symptoms like a sticking or hard-to-turn key.
- This is a simple, inexpensive, and highly recommended DIY repair that can be done in under an hour.
- Aftermarket brands like Dorman and Standard Ignition are reliable and readily available replacements.
- The new cylinder will come with new keys, meaning you will have a separate key for your ignition and doors.
Common Failure Symptoms in the 1977-1985 D150
An ignition lock cylinder failure on these classic Dodge trucks is a common issue due to age and mechanical wear. The most frequent complaint is the key becoming difficult to turn or getting stuck in the lock. You might find yourself needing to jiggle the key to get it to engage the 'start' position or to remove it after shutting the engine off. In more severe cases, the cylinder can fail completely, preventing you from turning the key at all, which will leave you stranded. Another sign is a loss of the spring-loaded feel; the key might feel loose or sloppy in the ignition. It's important to distinguish this from a bad ignition switch, which is the electronic part that the lock cylinder controls. If you have no power to the dashboard or accessories, the switch could also be at fault, but the mechanical problems of a sticking key point directly to the lock cylinder.
Choosing the Right Aftermarket Ignition Cylinder
For a 1977-1985 Dodge D150, finding a new OEM (Original Equipment Manufacturer) ignition lock cylinder from Mopar is highly unlikely. The aftermarket is your primary source for this part. The good news is that reputable aftermarket brands produce reliable replacements that meet or exceed the original quality. The two main brands you will encounter are Dorman and Standard Ignition (Standard Motor Products).
- Standard Ignition (SMP): A long-standing brand in the automotive aftermarket, often considered a professional-grade choice. They have a reputation for producing parts that fit and function correctly, making them a trusted option for many mechanics.
- Dorman: Known for providing a wide range of aftermarket parts, often with value in mind. Dorman parts are a popular choice for DIY repairs and are widely available. They are generally considered a reliable replacement for common-wear items like this lock cylinder.
Pro Tip: Both Dorman and Standard Ignition are solid choices for this repair. Given the simplicity of the part and the age of the vehicle, either brand will serve you well. Your decision can comfortably be based on price and availability. Both will come with a new set of keys, so you will have a separate key for your ignition and doors unless you have a locksmith re-key the new cylinder to match your old keys.

Frequently Asked Questions (FAQ)
Is this a difficult repair to do myself?
No, this is a very DIY-friendly job. For most 1977-1985 models, the process involves removing the plastic steering column covers, and then depressing a small retaining pin to release the old cylinder. You typically do not need to pull the steering wheel on these models, but you may need a set of Torx bits. The entire job can usually be done in under an hour with basic hand 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. This means you will have one key for the ignition and your original key for the doors. If you want to use a single key, you would need to take the new cylinder to a locksmith to have it re-pinned to match your original key before you install it.
What is the difference between the ignition lock cylinder and the ignition switch?
The ignition lock cylinder is the mechanical part your key goes into. The ignition switch is the electronic component that the lock cylinder turns. The switch is what actually sends power to the starter and other systems. If your key is physically stuck or won't turn, the cylinder is the problem. If the key turns fine but nothing happens, the switch might be the issue.
Are there any recalls for the ignition lock cylinder on a 1977-1985 Dodge D150?
No, there are no specific recalls found on the NHTSA database for the ignition lock cylinder for this vehicle range. Given the age of the truck, any safety-related issues would have been addressed decades ago. Failures today are due to normal mechanical wear and tear.
Technical Specifications
The primary specification to be aware of is whether your truck has a tilt or non-tilt steering column, as the replacement procedure can vary slightly. The aftermarket parts are direct-fit replacements that come with a new lock cylinder, two keys, and are typically finished in chrome or metal.
