- Identify if you have a B-Body (1966-78) or L-Body (1982-87) as internal parts differ.
- An aftermarket kit from Standard Ignition is a reliable and cost-effective solution, providing new locks and matching keys.
- Replacement is a manageable DIY job that requires removing the inner door panel.
Understanding Your Charger's Door Locks
If you own a classic Dodge Charger from the 1966-1987 model years, you're driving a piece of automotive history. It's important to know that this long production window covers two very different types of cars: the B-body (1966-1978) and the L-body (1982-1987). While they share a name, their parts, including door locks, can be different.
- 1966-1978 (B-Body): These classic muscle cars use a robust, all-metal mechanical lock system. Problems usually come from simple wear and tear over decades of use. The internal mechanisms can get gummed up with old lubricant and dirt, or the linkage rods can become disconnected.
- 1982-1987 (L-Body): These front-wheel-drive Chargers use a lighter-duty system. A common point of failure is the small plastic clips that hold the metal linkage rods in place. When these clips become brittle and break, the lock or the door handle may feel loose and stop working.
Symptoms of a Failing Door Lock Kit
A bad door lock is more than an inconvenience; it's a security risk. Watch for these common signs that it's time for a replacement:
- Key is hard to insert or turn: The tumblers inside the lock cylinder may be worn or damaged.
- Key spins freely in the lock: The connection between the lock cylinder and the linkage rod inside the door is likely broken.
- Lock knob on the door panel is stiff or won't move: The internal latch mechanism could be binding, or the connecting rods are bent.
- Outside door handle feels loose: On L-body models especially, this often points to broken plastic retaining clips for the linkage rods.
No Recalls or TSBs Found
Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any recalls or Technical Service Bulletins (TSBs) for door lock failures on the 1966-1987 Dodge Charger. Any issues you experience are likely due to the age and wear of the original components.
Choosing the Right Aftermarket Part
For a vehicle of this age, finding new Original Equipment Manufacturer (OEM) parts is nearly impossible. Your main options are used OEM parts from a salvage yard or a new aftermarket kit.
- New Aftermarket (Standard Ignition): An aftermarket kit from a reputable brand like Standard Ignition (also known as Standard Motor Products) is often the best choice. You get brand new components that haven't been exposed to decades of weather and use. These kits typically include two door lock cylinders and a new set of matching keys, ensuring a perfect match.
- Used OEM: A used part maintains originality, but you risk getting a part that is just as worn as the one you are replacing. It may also not come with a key, requiring a locksmith to re-key it.
Pro Tip: Consider a Complete Lock Set
Many aftermarket kits include not only the door locks but also the ignition lock cylinder and sometimes the trunk lock. This is a great opportunity to have one key that works for the entire car, just like it did from the factory.

Frequently Asked Questions
Can I replace just one door lock?
Yes, but kits are usually sold as a pair to ensure one key works for both doors. Replacing both at the same time is recommended for convenience.
Is replacing a door lock cylinder a good DIY project?
Yes, for someone with basic mechanical skills. The process involves removing the inner door panel to access the lock. It requires patience, as you'll be working in a tight space. Tools needed typically include screwdrivers, a socket set, and possibly a panel removal tool.
Will I need to have the new lock re-keyed?
No. New aftermarket door lock kits come with a new set of keys that are already matched to the new lock cylinders.
What is the hardest part of the replacement?
The most difficult part is often removing and re-installing the small retaining clip that holds the lock cylinder in the door, as well as re-connecting the linkage rod, all while working inside the door frame.
Technical Specifications
Kit typically includes: 2 door lock cylinders, 2 matching keys, gaskets, and retaining clips.
