Is Your Dodge W100 Door Lock Failing?
The door locks on a classic 1968-1974 Dodge W100 are simple, but they don't last forever. After decades of exposure to the elements and constant use, the internal parts of the lock cylinder wear down. Symptoms usually start small and get worse over time. Ignoring them can eventually lead to being unable to lock or unlock your truck door.
Symptoms of a Worn-Out Door Lock Kit
- Key is Hard to Turn: The most common sign of failure is a key that's difficult to insert, turn, or remove. This is caused by worn internal tumblers or debris inside the lock cylinder.
- Lock Feels Loose or Sloppy: If the entire lock cylinder wiggles in the door when you use the key, the retaining clip that holds it in place is likely broken or has fallen off.
- Lock Spins But Doesn't Work: You can turn the key 360 degrees, but nothing happens. This means the connection between the lock cylinder and the internal door latch rod is broken.
- Key Won't Go In: The keyway might be blocked by dirt, rust, or even a piece of a broken key.
Check the Linkage First
Before ordering a new lock kit, it's worth taking the door panel off to inspect the connecting rods and clips. Sometimes, the lock cylinder is fine, but the small plastic clip holding the rod has broken. This is a much cheaper and simpler fix if it's the only problem.
Choosing the Right Aftermarket Door Lock Kit
Finding a new original equipment (OEM) Mopar door lock set for a truck from this era is nearly impossible. The good news is that the aftermarket provides quality, affordable solutions. For a straightforward mechanical part like this, a reputable aftermarket brand is a reliable choice.
Standard Ignition (Standard Motor Products): Standard is a well-known brand that has been making automotive parts for decades. Their DL-2 Door Lock Kit is a direct fit for the 1968-1974 W100. These kits are designed to match original specifications and are made with materials like brass tumblers and die-cast zinc cores, which are suitable for daily use.
Important Note on Keys: A new aftermarket door lock kit will come with a new set of keys. These keys will not match your truck's ignition key. After installation, you will need one key for the ignition and a separate key for the doors.

Frequently Asked Questions (FAQ)
Is replacing the door lock kit a difficult job?
No, this is a great DIY project for a beginner. The process involves removing the inner door panel, releasing a clip, disconnecting a rod, and swapping the cylinder. It typically takes less than an hour per door and requires only basic hand tools.
Do I need to replace both door locks at the same time?
It is highly recommended. The locks are sold in pairs for a reason. If one lock has failed from age, the other is likely not far behind. Replacing both at once ensures they use the same key and saves you from doing the job a second time.
Can I have the new locks matched to my ignition key?
Yes, but not out of the box. You would need to take the new lock cylinders and your original ignition key to a locksmith. They can "re-key" the new tumblers to match your old key, but this service will have an additional cost.
Are there any recalls on 1968-1974 W100 door locks?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no safety recalls for the door locks on these trucks. Any issues you experience are due to normal wear and tear over the vehicle's long life.
