A Guide to Replacing the Door Lock Actuator on Your 2012-2016 Chrysler 300
If your power locks are making strange noises or have stopped working, it's likely a failed door lock actuator.
- A loud buzzing noise from the door is the most common sign of a failed actuator.
- This is a common failure, but there are no specific recalls for the 2012-2016 Chrysler 300 sedan.
- Replacement can be a complex DIY job, potentially requiring window removal for access.
- Verify if your car has "Thatcham Security Equipment" before ordering to ensure you get the correct part.
Is Your Chrysler 300 Door Lock Acting Up?
A common point of failure on the 2012-2016 Chrysler 300 is the door lock actuator. This part works hard, and over time, the internal motor and plastic gears can wear out. When this happens, you might notice the lock struggling to work, making noise, or failing completely. This guide will walk you through the symptoms, replacement options, and what to expect when tackling this repair.
Symptoms of a Failing Door Lock Actuator
A bad actuator usually gives you a few warning signs. If you notice any of these, it's time to start planning a replacement:
🎬 Watch: Why your Chrysler 300 door won't lock or unlock- Buzzing or Grinding Noises: The most common symptom is a loud buzzing or grinding sound from inside the door when you press the lock or unlock button. This is the sound of the motor spinning but the gears being too worn to move the lock.
- Inconsistent Operation: The lock may work sometimes but not others. It might require multiple presses of the button to engage.
- Total Failure: The door lock doesn't respond to the key fob or the interior power lock switch at all. You can only lock or unlock it manually.
- Locks Cycling Erratically: In some cases, a failing actuator can cause the locks to cycle on their own.
No Recalls or TSBs for the 300
While Chrysler has issued warranty extensions and Technical Service Bulletins (TSBs) for door lock actuators on their minivans (Town & Country), these do NOT apply to the 2012-2016 Chrysler 300 sedan. The issue on those vans was primarily with the sliding doors. As of now, there are no active recalls or specific TSBs for door lock actuator failure on the Chrysler 300 for this model year range.
Choosing the Right Aftermarket Part
When replacing the actuator, you have a choice between OEM (Mopar) and aftermarket parts. For a vehicle of this age, a quality aftermarket part offers a good balance of price and reliability.
- OEM (Mopar): This is the exact part your car was built with. It guarantees a perfect fit and function but comes at the highest cost.
- Aftermarket (Standard Ignition): Brands like Standard Ignition (also known as Standard Motor Products or SMP) specialize in electrical components and are known for producing quality parts that meet or exceed original specifications. They provide a reliable alternative to OEM without the high price tag.
Pro Tip: The most critical step is ordering the correct part for the specific door (e.g., front right, rear left). Also, some 2012 models have an option for "Thatcham Security Equipment." You must match your new part to your vehicle's original configuration. Check the OEM part number off the old unit before ordering if possible.

Cost estimates are approximate and can vary by location and vehicle specifics.
Frequently Asked Questions
Can I replace just one door lock actuator?
Yes. The actuators fail individually, so you only need to replace the one that is broken. If one has failed, it's not uncommon for another to fail in the near future due to similar age and wear, but it's not necessary to replace them all at once.
Is this a difficult DIY job?
This is a moderately difficult job. It requires removing the interior door panel, which has several screws and clips. The hardest part is working inside the door, disconnecting the old actuator, and connecting the new one. For the front doors on the Chrysler 300, some guides suggest you must remove the window glass to get enough clearance, which makes the job significantly more complex. If you are not comfortable with this, it may be best to leave it to a professional.
🎬 Watch this walkthrough for front door actuator and window removalDo I need any special tools?
You will need basic hand tools like a socket set, screwdrivers, and a T30 Torx bit for the actuator bolts. A plastic trim removal tool is highly recommended to avoid scratching your door panel. 🎬 See how to safely remove the interior door panel If the window needs to be removed, the job becomes more involved.
Will the new actuator need to be programmed?
No. The door lock actuator is a simple electric motor and does not require any programming. As long as you have the correct part for your vehicle, it is a plug-and-play installation.
