Key Takeaways
  • For the 1966-1976 Coronet, a new aftermarket door lock kit is the most practical and available option.
  • Standard Ignition is a reputable brand offering direct-fit replacement kits for this vehicle.
  • Installation is a straightforward DIY task that requires removing the door panel to access the lock cylinder.
  • These kits typically only replace the door locks and will not be keyed to match your existing ignition or trunk lock.
The door lock kit for a 1966-1976 Dodge Coronet is a fully mechanical system. It consists of the lock cylinders—the part where you insert your key—along with a matching set of keys. These kits are designed to replace worn, damaged, or missing door locks. When you turn the key, the cylinder rotates and moves a connecting rod inside the door, which then operates the latch mechanism to lock or unlock the door. Replacing the kit is the primary way to fix a faulty lock or to get a new, matching set of keys for your vehicle's doors.

Signs of a Failing Door Lock

The door locks on a classic Dodge Coronet are simple and durable, but after decades of use, they can wear out. The most common issues are physical wear and tear. You might find your key is difficult to insert and turn, or it feels gritty. In some cases, the lock may not work at all, or you may have lost the keys and need a fresh start. These are all signs that it's time for a new door lock kit.

Choosing the Right Aftermarket Lock Kit

For a vehicle from this era, finding new original equipment (OEM) parts is nearly impossible. While you could search for used OEM locks from a salvage yard, they will likely have the same age-related wear as your current ones. The most practical and reliable solution is a new aftermarket door lock kit.

Brand Spotlight: Standard Ignition is a well-known and trusted brand that produces replacement parts for classic vehicles. Their door lock kits are manufactured to fit and function like the original, offering a dependable and affordable solution for Coronet owners. Kits typically include two lock cylinders, a matching pair of keys, and the necessary retaining clips and gaskets for installation.

Known Issues and Recalls

There are no active recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the door locks on the 1966-1976 Dodge Coronet. Any problems you encounter are due to the normal aging and wear of these 50+ year-old mechanical components, not a manufacturing defect.

Frequently Asked Questions

Do I need to replace both door locks at the same time?
Yes. Door lock kits are sold as a matched set with one pair of keys that operate both cylinders. You should replace both to ensure a single key works for both doors.

Will this new kit match my ignition or trunk lock?
No. Standard door lock kits are keyed only for the doors. If you want a single key for the doors, ignition, and trunk, you would need to purchase a more comprehensive lock set.

Is replacing the door lock kit a difficult job?
No, this is a very feasible DIY project for most owners with basic tools. The process involves removing the interior door panel, releasing a retaining clip, disconnecting a linkage rod, and swapping the old cylinder for the new one.

What tools will I need for the installation?
You will typically need a set of screwdrivers, pliers (needle-nose are helpful), and possibly a clip removal tool. The entire process for both doors can usually be completed in one to two hours.
