Symptoms of a Failing Door Lock Kit
On a vintage vehicle like the Dodge Colt, door locks are simple but can fail from decades of use. Watch for these common signs that your lock cylinders need replacement.
- Key is Difficult to Insert or Turn: If you feel resistance, stiffness, or have to jiggle the key to get it to work, the internal tumblers of the lock cylinder are likely worn or corroded.
- Key Spins Freely in the Lock: This indicates a broken connection between the lock cylinder and the latch mechanism inside the door. The cylinder is no longer engaging the lock rod.
- The Lock Feels Loose or Wobbly: The retaining clip or the cylinder housing itself may be broken or worn out, causing the entire assembly to feel insecure in the door.
- Key Won't Go In or Comes Out While Turning: Debris, corrosion, or a bent tumbler pin inside the cylinder can block the key or cause it to bind.
OEM vs. Aftermarket Door Lock Kits
For a vehicle as old as the 1971-1984 Dodge Colt, finding new original equipment manufacturer (OEM) parts from Mopar is nearly impossible. The dealership network has not stocked these parts for many years.
Part Availability
| Part Type | Availability | Notes |
|---|---|---|
| New OEM | Unavailable | No longer manufactured or sold by Dodge/Mopar. |
| New Aftermarket | Readily Available | The most practical and reliable option. Brands like Standard Ignition provide complete kits. |
| Used OEM | Scarce | Can be sourced from junkyards, but the condition will be worn and there is no guarantee of longevity. Keys may be missing. |
Your primary and best choice is a new aftermarket kit. Companies like Standard Ignition (also known as Standard Motor Products or SMP) produce direct-fit replacement door lock kits for the Dodge Colt. These kits are designed to match the original's specifications for a precise installation and are made from modern materials like die-cast zinc and brass tumblers to ensure good operation. Given the age of the vehicle, an aftermarket kit is the standard repair method used by mechanics and owners.
A Note on Keys
An aftermarket door lock kit will come with a new set of keys that will only operate the door locks. They will not match your original ignition key. You will need to carry a separate key for your doors and ignition, which was common for many vehicles of this era.
Known Issues, Recalls, or TSBs
Searches for official recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) show no specific issues related to the manual door locks on the 1971-1984 Dodge Colt. Any problems you encounter are most likely due to the normal wear and tear of a 40+ year-old mechanical part rather than a manufacturing defect.
Estimated Replacement Costs
The cost to replace your door lock kit is very reasonable, especially since the part itself is affordable. Labor costs are low because the job is straightforward.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Door Lock Kit | $22 - $30 |
| Shop Labor | $100 - $150 |
| Total Estimated Cost | $122 - $180 |
These are estimated costs. Prices for parts and labor can vary by supplier and location. The estimate assumes replacement of both front door locks.
Frequently Asked Questions (FAQ)
Is replacing the door lock kit a good DIY job?
Yes, for someone with basic tools and mechanical ability, this is a very manageable DIY project. The process involves removing the interior door panel, unclipping the old lock cylinder, and installing the new one. It typically does not require specialized tools.
What comes in a typical aftermarket door lock kit?
A complete kit from a brand like Standard Ignition usually includes two new door lock cylinders (for driver and passenger sides), two new keys, and the necessary retaining clips or brackets for installation.
Will I need to replace both door locks at the same time?
It is highly recommended. The kits are sold with two matched lock cylinders and a single set of keys. If one lock has failed due to age, the other is likely not far behind. Replacing both at once ensures they are keyed the same and saves you from having to do the job twice.
My Colt has power locks. Will this kit work?
The 1971-1984 Dodge Colt was not typically equipped with power locks from the factory. The available aftermarket kits are for the standard manual locking system. If your car has a rare dealer-installed or a previous owner's custom power lock system, this mechanical kit may still be compatible, but the power actuator would be a separate component.
Technical Specifications
Kit typically includes: (2) Chrome-finish Door Lock Cylinders, (2) Matching Keys, (2) Retaining Brackets/Clips.
