Dodge 600 Door Lock Kit and Cylinder Replacement Guide (1983-1988)
If your key is sticking or your door won't lock, this guide is for your 1983-1988 Dodge 600.
- New OEM Mopar door lock kits are no longer produced; your primary option is a new aftermarket kit.
- Standard Motor Products (SMP) is the main aftermarket brand, offering a reliable and affordable replacement.
- This is a mechanical part. It will not solve issues with your power door lock system.
- Replacement is a manageable DIY task that requires removing the interior door panel.
Signs of a Failing Door Lock Cylinder
Over decades of use, the mechanical parts inside your Dodge 600's door lock cylinders wear down. When they start to fail, you'll notice clear symptoms. Ignoring them can lead to being locked out of your car or being unable to secure it.
- Key is Difficult to Insert or Turn: You may feel like you have to jiggle the key or force it to get the lock to work. This is a sign of worn tumblers or a worn-out key.
- Lock Cylinder is Loose: The entire lock cylinder may feel loose or spin in the door. This can happen if the retaining clip has broken or come loose.
- Key No Longer Works: The key goes in but won't turn at all, meaning the internal pins are either seized, broken, or too worn to align properly.
- Door Won't Lock/Unlock with Key: Even if the key turns, the connection to the internal latch mechanism might be broken, preventing the door from actually locking or unlocking.
Choosing the Right Aftermarket Part
For a vehicle like the 1983-1988 Dodge 600, finding new Original Equipment (OEM) parts from Mopar is nearly impossible. Your realistic options are a used OEM part from a salvage yard or a new aftermarket kit.
OEM vs. Aftermarket Door Lock Kits
| Part Type | Pros | Cons |
|---|---|---|
| New Aftermarket (Standard Ignition) | Readily available, affordable, new components, comes with new keys. | May not have the exact same feel as the original. |
| Used OEM | Original factory part. | Difficult to find, unknown condition and history, may fail soon, keys may be worn. |
The most common and reliable choice is a new aftermarket kit. Standard Motor Products (SMP), also sold under brands like Carquest, is the primary manufacturer for this part. Their kits are designed as direct replacements and are built with quality materials like brass tumblers and die-cast zinc cores to meet or exceed the original's performance.
DIY Replacement Tips
Replacing the door lock cylinder is a straightforward job that most DIY mechanics can handle. While no specific videos exist for the Dodge 600, the process is similar for most cars of this era. You will need to remove the interior door panel to access the back of the lock cylinder. The cylinder is typically held in place by a C-shaped clip. Using a screwdriver or pliers, you can remove the clip and the rod connecting the cylinder to the latch mechanism. Installation is the reverse of removal. Be careful not to drop the clip or small parts inside the door.
Pro Tip: Before putting the door panel back on, test the new lock and key multiple times with the door open. Ensure the key turns smoothly and that it properly operates the lock mechanism. This will save you the headache of having to take the door apart again.
Frequently Asked Questions
Does this kit fix my power door locks?
No. This is a mechanical kit for the key cylinder only. If your power locks are not working but the key works, you likely have a problem with the power lock actuator, switch, or wiring, not the lock cylinder.

No. The kit comes with a new set of two keys that are matched to the new lock cylinders. You will have a separate key for your door and ignition unless you replace the ignition cylinder at the same time with a matched set.
What comes in a typical door lock kit?
The Standard Ignition door lock kit for the Dodge 600 includes the door lock cylinders, two new keys, and the necessary mounting hardware like brackets or clips.

For someone with basic tools and experience, this is a relatively easy job that should take about an hour per door. The main steps are removing the door panel and maneuvering your hand inside the door to release a retaining clip.
