What is a trunk lock actuator?
Trunk lock actuators are responsible for controlling the locking and unlocking motion of the trunk lid. They use an electric motor to convert signals from the key fob or interior release lever into the physical action of the trunk latch assembly that opens the lid. Lock actuators allow easy access to the trunk for storing and securing your belongings.
When should I replace the trunk lock actuator on my car?
There is no set replacement schedule for trunk lock actuators. That means the only time you’ll need to replace yours is when it fails. Here are the most common signs that you may need a new trunk lock actuator:
The trunk doesn’t open even after the actuator “clicks”
The trunk release buttons don’t work properly
The trunk actuator clicks continuously
You can open the trunk by putting your key in the lock cylinder but not by using your key fob or interior release lever
Keep in mind: These issues can indicate other trunk issues, so it’s always wise to visit a certified mechanic for an accurate diagnosis.
How often should I replace my trunk lock actuator?
There is no set replacement interval for trunk lock actuator motors. However, they are subject to wear and tear over time and can fail with repeated use. You should replace yours if it stops working and you can’t use your cabin release button or key fob to open the trunk.
Can I replace my trunk lock actuator myself?
You can DIY a trunk lock actuator replacement—if you have the right know-how and access to the proper tools. The replacement is generally classified as a mid-level repair job, and moderately experienced home mechanics should have no issues completing it. That said, if you’re a car repair novice or don’t have access to the right tools, you should contact a professional technician.
