Having trouble with your power door locks? Here’s what you need to know about fixing them.
- A single door failing to lock or unlock electronically is the primary symptom of a bad actuator.
- Listen for buzzing or grinding noises from the door, which are early warning signs of failure.
- This is a DIY-friendly repair for those with basic tools, saving you significant labor costs.

Is Your Lincoln Navigator's Door Lock Acting Up?
If a door on your 2012-2017 Lincoln Navigator won't lock or unlock with the power switch, you're likely dealing with a failed door lock actuator. This is a common issue on many vehicles as they age. The actuator is the motor inside the door that does the physical work of locking and unlocking. When it wears out, you lose the convenience and security of your power lock system. Fortunately, replacing it is a straightforward repair.

A failing door lock actuator usually gives a few warning signs before it stops working completely. If you notice any of these symptoms on a single door, the actuator is the most likely cause.
- Strange Noises: You might hear a buzzing, grinding, or clicking sound from inside the door when you try to lock or unlock it. This is often the sound of worn internal gears struggling to move.
- Erratic Operation: The lock might work sometimes but not others. It may lock but not unlock, or it might seem to lock or unlock on its own.
- Slow Response: A noticeable delay between pressing the button and the lock engaging or disengaging is a sign of a weak actuator motor.
- Total Failure: The lock doesn't respond at all to the key fob or the interior power lock switch, forcing you to use the manual lock.
- Related Electrical Issues: Since the actuator assembly can contain the door ajar switch, a failure might cause the "Door Ajar" light to stay on or the alarm system to malfunction.
Known Issue: Latches Freezing in Cold Weather
While not a recall for the Navigator specifically, the closely related 2015-2017 Ford F-150 had a Technical Service Bulletin (TSB 16-0155) for door latches that would not work in freezing temperatures. This was caused by water entering the door and freezing inside the latch mechanism. Owners reported doors that would not open or, more commonly, would not latch closed after being opened in the cold. The official fix involved installing water shields and lubricating the latch components. If you live in a cold climate and experience these issues, a new, well-greased actuator assembly can help resolve the problem.

When replacing the door lock actuator on your Navigator, you have a choice between original equipment (OEM) from the dealer and aftermarket parts. OEM parts are what your vehicle was built with, but they come at a higher price. Aftermarket parts are designed to be direct replacements and are often much more affordable.
For a part like a door lock actuator, which requires removing the entire door panel to replace, reliability is key. Some owners prefer to pay more for an OEM part, believing it offers the best guarantee of fit and long-term function. However, quality aftermarket brands offer a dependable alternative at a better price.
Brand Spotlight: Standard Ignition (SMP)
Standard Motor Products, which makes Standard brand parts, is a well-regarded manufacturer of automotive electrical components. Their actuators are engineered to meet or exceed original specifications and often come with a strong warranty, such as 3 years or 36,000 miles. This makes them a solid choice for a reliable repair without paying the high dealer price for an OEM part.
How Much Does a Door Lock Actuator Replacement Cost?
The total cost depends on whether you do the work yourself or take it to a repair shop. The part itself is not expensive, but the labor to install it can add up.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Part | $195 - $219 |
| New Aftermarket Part | $30 - $60 |
| Shop Labor | $125 - $185 |
| Total (Shop Repair) | $320 - $404 (with OEM part) |
| Total (DIY Repair) | $30 - $60 (with aftermarket part) |
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 has stopped working. If one has failed due to age, others may not be far behind, but it is not necessary to replace them all at once.
Is this a difficult repair to do myself?
For someone with basic tools and some experience, this is a manageable DIY job. The process involves removing the interior door panel, carefully disconnecting the old actuator from the rods and electrical connector, and installing the new one. It typically requires a 7mm socket, a T27 Torx driver, and some trim removal tools. 🎬 Watch a mechanic demonstrate how to remove the door panel. Expect it to take 1.5 to 2.5 hours for the first door.
Will an aftermarket actuator work with my key fob?
Yes. A new door lock actuator, whether OEM or aftermarket, is a direct replacement for the failed motor. It will respond to the signals from your vehicle's existing key fob and interior switches just like the original part did.
My doors lock and unlock by themselves. Is that the actuator?
It could be. A failing actuator can sometimes cause erratic behavior like locking or unlocking on its own. However, this symptom can also point to an issue with the door lock switch or the Body Control Module (BCM), which is the computer that controls the locks. If the problem happens on multiple doors at once, the issue is less likely to be a single actuator.
