Is Your Dodge 400 Door Lock Failing?
For a car like the 1982-1983 Dodge 400, problems with the door locks are almost always due to simple mechanical wear and tear. After 40 years, the small metal parts inside the lock cylinder wear down. Your key might get harder to turn, or you might feel the lock getting gritty and stiff. Eventually, the lock might spin freely without doing anything, or the key might not go in at all.
Common Symptoms of a Bad Door Lock Cylinder
- Key is difficult to insert or turn: This often indicates worn tumblers inside the cylinder or a worn-out key.
- Lock cylinder spins in the door: If the key and cylinder turn 360 degrees without locking or unlocking, the internal mechanism has failed.
- Key feels loose or won't work: The lock may be too worn to properly align with the key.
- Sticking or stiff lock: Dirt, grime, or corrosion inside the lock can make it hard to operate.
Choosing the Right Aftermarket Part
For a vintage vehicle like the Dodge 400, finding new original equipment (OEM) parts from Chrysler is not a realistic option. Your choices are a used lock from a salvage yard or a new aftermarket kit.
- Used OEM: A used lock will be just as old and likely as worn as the one you are replacing. You also have to deal with having a separate key for your doors and ignition.
- New Aftermarket: A new aftermarket kit is the most practical and reliable solution. It provides brand-new components and a matching set of keys for both doors.
Available Brand: Standard Ignition
The primary brand available for this part is Standard Ignition (SMP). They are a well-known company that has been making quality automotive parts for decades. Their door lock kits are designed to be a direct replacement for the original, ensuring a good fit. They are made with die-cast zinc cores and brass tumblers, which is a quality construction for this type of part. For the Dodge 400, this is a solid and dependable choice.
Cost of Replacing Your Door Lock Kit
| Part Type | Typical Cost | Notes |

| New Aftermarket (Standard Ignition) | $22 - $32 | This is the recommended option. Includes two new locks and matching keys. |
| New OEM | Not Available | These parts have not been produced by the manufacturer for many years. |
| Used OEM | $10 - $25 | Sourced from junkyards. Condition is not guaranteed and will not come with a warranty. |

A Note on Power Locks
This door lock kit is for the mechanical key cylinder only. It does not fix issues with factory power locks. Problems with power lock systems on cars of this age are usually caused by bad wiring, faulty switches, or failed actuators, not the lock cylinder itself.
Frequently Asked Questions (FAQ)
Can I replace just one door lock?
You can, but the aftermarket kits are sold as a pair with matching keys. Installing the full kit ensures both your driver and passenger doors use the same new key, which is more convenient.
Is replacing the door lock kit a DIY job?
Yes, for someone with basic mechanical skills and tools. The process involves removing the inner door panel, releasing a retaining clip, disconnecting a small rod, and swapping the cylinder. It can be a bit tight to work inside the door, but it does not require specialized tools.
Will this kit match my ignition key?
No. This kit comes with its own set of keys that will only operate the door locks. You will continue to use your original key for the ignition.
Were there any recalls on the 1982-1983 Dodge 400 door locks?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or investigations related to the door locks on the 1982-1983 Dodge 400.
