Trunk Latch Motor Clicking but Won't Open: Causes and Fixes

You press the trunk release button, hear a distinct clicking sound from the latch motor, but the trunk stays shut. That click tells you the motor is getting power and trying to work but something is preventing the latch from releasing. This is one of the most frustrating trunk problems car owners face because it feels like it should open. Understanding what's happening behind that click can save you time, money, and the headache of prying your trunk open with the wrong tools.

Why does the trunk latch motor click but not release?

The clicking noise means the trunk latch motor is receiving an electrical signal and attempting to actuate. The motor itself isn't necessarily broken. In most cases, the problem lies in the latch mechanism rather than the motor. Here's what's likely happening inside your trunk lid:

Worn or seized latch pawl: The pawl is the hook-shaped piece that grabs onto the striker bar. Over time, grime, rust, or dried-out grease can prevent it from rotating freely.
Broken internal linkage: A small rod or clip connects the motor to the latch release. If that clip has popped off or the rod has bent, the motor spins but doesn't transfer force to the pawl.
Misaligned striker or latch: If the trunk has been slammed hard repeatedly or the car was in a minor rear collision, the latch and striker may no longer line up. The latch grabs tighter than it should, and the motor doesn't have enough force to overcome it.
Weak motor or worn gears: The motor's internal plastic gears can strip over time. The motor still clicks as it tries to turn, but it can't generate enough torque to pop the latch.

Is this the same as a trunk that won't open with the key fob?

Not exactly, though they're related. When the trunk latch motor clicks but the trunk won't pop open, you're hearing the motor respond. A trunk that doesn't open with the key fob at all no click, no sound often points to an issue with the remote key fob signal or the trunk release wiring. In your case, the electrical side is working. The problem is mechanical.

That said, both issues can stem from a deteriorating trunk latch assembly. If you've experienced intermittent fob problems and now the motor clicks without releasing, the entire latch mechanism may need inspection.

How do you open the trunk when the latch motor clicks but nothing happens?

You have a few options depending on your car's design:

Use the physical key: Most vehicles have a keyhole on the trunk lid. Insert the mechanical key and turn it. This bypasses the motor entirely and manually releases the latch.
Access through the rear seat pass-through: Many sedans have fold-down rear seats or a small pass-through panel. Reach through and pull the interior trunk release cable by hand.
Use the emergency trunk release: Federal law requires an interior glow-in-the-dark trunk release handle in all vehicles made after 2002. If someone is inside the trunk, they can pull it. But if you're trying to get in from outside, you'll need to access it through the rear seats. If that handle itself isn't working, check out these troubleshooting steps for a non-functioning emergency release.
Apply gentle pressure while pressing the release: Push down on the trunk lid firmly while someone presses the trunk release button. This can relieve pressure on a misaligned or binding latch.

Can you fix a clicking trunk latch motor yourself?

In many cases, yes. Start with the simplest fixes first:

Clean and lubricate the latch: Open the trunk manually using one of the methods above. Spray a quality penetrating lubricant like PB Blaster or silicone spray directly into the latch assembly. Work the latch open and closed by hand several times. Wipe away excess grime.
Check the linkage clips: Remove the interior trunk trim panel (usually held by a few push-pin fasteners). Look at the rod running from the motor to the latch. Make sure the plastic clips holding the rod in place are intact and seated properly.
Inspect the latch pawl and spring: With the trim off, watch the mechanism operate when someone presses the trunk release. If the motor turns but the pawl barely moves, the internal spring may be broken or the gears may be stripped.

If cleaning and re-connecting the linkage doesn't solve the problem, the latch assembly itself likely needs replacement. Many common trunk latch mechanism problems are resolved by swapping out the full assembly rather than trying to rebuild individual parts.

What tools and parts do you need?

Trim removal tool (plastic pry tool to avoid scratching panels)
Silicone spray or white lithium grease
10mm socket and ratchet (for most latch mounting bolts)
Replacement trunk latch assembly (if needed) typically $30–$80 depending on vehicle
Electrical multimeter (to verify the motor is receiving proper voltage)

What are common mistakes people make with this problem?

Forcing the trunk open with a screwdriver: This damages the latch, the trunk lid, and the paint. Use the key or interior access methods instead.
Replacing the motor without checking the mechanism: If the linkage or pawl is the real problem, a new motor will click the same way.
Ignoring intermittent clicking: If the trunk sometimes opens and sometimes doesn't, the latch is failing progressively. Fix it before it locks you out completely.
Using WD-40 as a long-term lubricant: WD-40 works as a short-term penetrant but dries out quickly. Use white lithium grease or a dedicated latch lubricant for lasting results.

How much does it cost to have a shop fix this?

A dealership or independent shop will typically charge one to two hours of labor for diagnosis and latch replacement. At average labor rates, expect $100–$250 total including parts on most mainstream vehicles. Luxury vehicles with electronic trunk actuators may run higher. Getting the trunk open first either with a key or through the rear seats keeps costs down since the shop won't need to spend extra time on access.

Quick diagnostic checklist

✅ Can you open the trunk with the physical key? (If yes, the problem is mechanical, not electrical.)
✅ Do you hear the motor clicking when you press the release? (If yes, power is reaching the motor.)
✅ Can you access the trunk through the rear seats? (If yes, inspect the latch and linkage from inside.)
✅ Does pressing down on the trunk lid while activating the release help it open? (If yes, misalignment is likely.)
✅ Is the linkage rod connected to the latch with intact clips? (If not, re-clip or replace the rod.)
✅ Does the latch move freely after lubrication? (If not, the assembly is likely seized or internally broken.)
✅ Does the motor spin freely when the latch assembly is removed? (If yes, the motor is fine replace the latch.)

Start with the physical key to get the trunk open, then clean and lubricate the latch. If the clicking continues without release, inspect the linkage and plan on replacing the full latch assembly. Most of these repairs take under an hour in a home garage with basic hand tools.
