Chrysler 300 Door Lock Actuator Guide for 2017-2023 Models
If your Chrysler 300 door locks are acting up, this guide explains how to diagnose and fix the problem with a new aftermarket part.
- A single failed door lock is typically a bad actuator, while all doors failing at once points to a fuse or relay.
- Symptoms include unresponsive locks and buzzing or grinding noises from the door.
- Aftermarket brands like Standard Ignition offer a cost-effective and reliable alternative to more expensive OEM parts.
- Replacement is a feasible DIY task for those comfortable with removing the interior door panel, but be sure to order the correct part for the specific door.
Isolating a Faulty Door Lock Actuator
When a single door on your Chrysler 300 stops responding to the key fob or the power lock switch, the problem is almost always the actuator motor within that door. If all doors fail to lock at once, the issue is more likely a fuse or a central relay. A common first sign of failure is an unusual noise, like a buzzing or grinding sound, when you try to lock or unlock the doors. 🎬 Learn more about the common symptoms of a bad door lock actuator. You might also notice that the lock works sometimes but not others.
Diagnosing the Right Door
Before buying a part, confirm which door is failing. Cycle the locks with your key fob while standing outside the car, then test each door. Also, use the master switch on the driver's door and listen for abnormal sounds from a specific door. This simple test can save you from ordering the wrong part.
Known Issues, Recalls, and Service Bulletins
As of early 2026, there are no active recalls specifically for the door lock actuators on the 2017-2023 Chrysler 300. Searches of the National Highway Traffic Safety Administration (NHTSA) database and for Technical Service Bulletins (TSBs) did not show a widespread, recognized defect for this part on these model years.

Failure is typically due to the mechanical parts and small electric motor wearing out from frequent use.
Choosing the Right Aftermarket Actuator
When replacing a door lock actuator, you have the choice between an original equipment manufacturer (OEM) part from Mopar or an aftermarket part. For the 2017-2023 Chrysler 300, aftermarket actuators offer significant cost savings and are a practical choice for most owners.
- OEM (Mopar): These are the exact same parts your vehicle was built with. They guarantee a perfect fit but come at a higher price.
- Aftermarket (Standard Ignition): Brands like Standard Ignition produce direct-fit replacement parts that are designed to meet or exceed original specifications. They provide a reliable repair at a much lower cost, making them an excellent value. For a component like a door lock actuator, where the technology is straightforward, a quality aftermarket part is a smart financial decision.
Common Ordering Mistake
Door lock actuators are specific to each door. The front driver's side, front passenger's side, rear driver's side, and rear passenger's side actuators are all different parts. Double-check that you are ordering the correct part for the specific door you need to repair.
