Ignition Lock Cylinder Guide for the 1977-1985 Dodge W150
If your key is sticking or won't turn, it's likely time for a new ignition lock cylinder.
- A key that is hard to turn or gets stuck is the most common symptom of a failing ignition lock cylinder on a W150.
- Aftermarket brands like Standard Ignition and Dorman offer reliable and affordable replacements.
- Replacement is a manageable DIY task but requires special tools like a steering wheel puller and a lock plate compressor.
- The new cylinder will come with new keys; your old keys will no longer work in the ignition.
Is Your Ignition Key Giving You Trouble?
If you own a classic 1977-1985 Dodge W150, you know these trucks are tough. However, after decades of use, some parts just wear out. The ignition lock cylinder is a common failure point. You might notice the key is hard to turn, gets stuck, or you have to jiggle it to get the ignition to work. In some cases, the internal tumblers wear down so much that the cylinder becomes loose in the steering column. These are all signs that the lock cylinder needs to be replaced.
Common Failure Symptoms
- Key is difficult to turn: You may find it takes a lot of force to turn the key from the 'off' position to 'run' or 'start'. This is the most common sign of worn internal parts.
- Key gets stuck: The key may go in but won't turn, or it may get stuck in one position and be difficult to remove.
- Loose and wobbly key: If the key feels very loose when inserted, the cylinder is likely worn out. In severe cases, the entire cylinder might feel loose within the steering column.
- Engine won't crank: While this can be caused by many issues, a failed lock cylinder can prevent the ignition switch from being activated, meaning the engine won't even try to start.
Choosing the Right Aftermarket Part
For a vehicle from this era, finding a new original equipment (OEM) part is nearly impossible. The good news is that several reputable aftermarket companies produce quality replacements that are affordable and readily available. The two main brands you will encounter are Dorman and Standard Ignition (Standard Motor Products).
| Brand | Our Assessment |
|---|---|
| Standard Ignition (SMP) | Often considered a top-tier aftermarket brand, Standard Motor Products parts are trusted by professional mechanics. They are known for using quality materials like brass tumblers and for manufacturing parts that meet or exceed original specifications for a precise fit. |
| Dorman | Dorman is a well-known brand that provides a direct replacement for the original part. They offer a reliable and cost-effective solution that gets the job done. For some vehicles, Dorman includes extra tumblers to re-key the new cylinder to your old key, though this is less common for this specific application. |
Pro Tip: Since both brands offer a solid replacement, the best choice often comes down to availability and price at the time of purchase. For a straightforward mechanical part like this on a classic truck, either brand will serve you well.
Cost of Replacing the Ignition Lock Cylinder
The cost to fix this issue is very reasonable, especially if you do the work yourself. The part itself is inexpensive, but labor can add up if you take it to a shop.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Part | $30 - $36 |
| Shop Labor | $100 - $200 |
| Total (Shop Repair) | $130 - $236 |
Note: Labor costs are an estimate. Shops in different areas have different rates. This job on an older truck is typically simpler than on a modern car, so labor should be on the lower end of typical ignition replacement costs.
Frequently Asked Questions
Can I replace the ignition lock cylinder myself?
Yes, this is a DIY-friendly job if you are comfortable with basic auto repair and have the right tools. The process involves disconnecting the battery, removing the steering wheel, and using a special lock plate compressor tool to access the cylinder. There are several helpful video guides online that show the process on similar Dodge trucks.
Will I need special tools for the job?
Yes. You will need a steering wheel puller and a lock plate compressor tool. These can often be rented from auto parts stores if you don't want to buy them.
Will my old key work with the new cylinder?
No. The new ignition lock cylinder will come with a new set of keys. Since the 1977-1985 W150 does not use chipped keys, you don't need to worry about programming. You will simply have one key for the ignition and your original key for the doors.
Is a hard-to-turn key always the lock cylinder?
Not always, but it is the most likely cause. A worn-out key can also cause issues. Before replacing the cylinder, try using a spare key if you have one. If the spare works smoothly, you may just need a new key. If the problem persists with all keys, the cylinder is the culprit.
