7 Solutions For honda accord sport trunk won’t open Problems:

By now we have good knowledge about the factors why a sport trunk on a honda accord won’t open.

So, now it’s essential to know how these problems can be fixed. The most potential ways of fixing these problems will be the following:

1. Jammed sport trunk lock: clean the lock

When your honda accord sport trunk won’t open with the key, the first thing to do is verify the lock if it is jammed.

If you prefer an electrical or power lock system for opening the trunk, the lock can be clogged with dust and debris. So, check the lock if it is corroded or dusty.

If you find it blocked, the easiest solution is to spray some wet cleaners to unclog it. You can use WD-40 for an instant result.

Spray the wet cleaner inside the keyhole and leave it for 10 minutes. Now put the key again into the lock and jiggle it until you get the honda accord sport trunk lock working back.

The price of a WD-40 cleaner will be between $19.99 and $23.35. If you do the job yourself, you won’t have any further costs to solve the issue.

But if you take help from an auto locksmith to diagnose and fix the problem, it will cost around $50 as the labor costs. 

2. Broken keys inside the lock: pull out the key and insert a new one

If you don’t use the keys manually to open the sport trunk, the keys can be corroded badly. The key can also lose its actual shape or teeth. So, it can be broken when you put it inside the trunk lock and try to jiggle it.

Even it may refuse to enter inside the lock. In this situation, the easiest solution is to throw out the damaged key and get a new one.

3. Broken sport trunk lock mechanism: check the lock and repair or replace it as needed

When a honda accord sport trunk lock key fails to turn inside the lock, the problem is probably with the lock mechanism.

If any part of the trunk lock such as the lock cylinder or the lock retaining clip is broken, the trunk won’t be able to open.

So, visually inspect the lock if there are any broken parts. If YES, the lock needs to be repaired or replaced.

To make sure what you should do with the broken lock, consult with a professional locksmith to prevent further damage to the trunk.

On average, the repairing cost for a broken sport trunk on a honda accord will be between $158 and $198.

The labor cost will be estimated at around $50, while the parts will be priced between $100 and $153.

4. Insufficient lubricant: lubricate the mechanism of the lock

The parts of a honda accord sports trunk should be lubricated regularly. As time goes by, the mechanism of a trunk lock will start tighter.

So, if the key enters into the lock but fails to turn properly and open the trunk, the most possible reason is insufficient lubricant.

In this case, check the moving parts of the trunk to see if they’re properly lubricated. If you find the parts are dusty, creaked, or jammed, lubricate them as needed.

The best lubricant for a honda accord sport trunk will be graphite powdered or silicon-based lubricants.

5. Faulty key fob: check the fob and replace it

If you want to open the honda accord sport trunk electrically but it doesn’t work, the main culprit for this problem can be a faulty key fob. The most common reason for the key fob’s failure is a dead battery.

So, the first step to be done is replacing the old battery with a new one. After that, check the key fob to see if it is working. If the honda accord sport trunk is still not unlocked, the key fob may need to be reprogrammed.

If the key fob still fails to respond, check the buttons if they are broken or jammed. If yes, repair them as needed. After repairing the issues, try opening the trunk again to see if the problem is solved.

If the key fob isn’t corrected yet, it’s good to get a new honda accord sport trunk key fob.

The fixing cost of a faulty remote key fob on a honda accord is between $500 and $850. It depends on whether you go for a mechanic or not.

A new key fob will be priced around $450, whereas the cost for reprogramming the fob can be between $50 and $100.

6. Faulty trunk lock latch: replace it if it is broken

Another common reason for not opening the trunk on your honda accord is a defective trunk lock latch. An electrical latch is mounted on the lock mechanism to operate the latch and open the trunk from a distance from the car.

If the key fob is working nice but still doesn’t allow the trunk to be unlocked, check the trunk latch if it is faulty. This metal part of the car can be corroded, dusty, or sticky over time.

Once it gets into such kind of damage, the honda accord sport trunk will refuse to unlock when you press the key fob or insert the key. In this case, diagnose the trunk latch to see if it is faulty.

If you find the latch is damaged or broken, it’s better to replace it instead of repairing it.

The average cost for a broken sport trunk latch replacement is between $200 and $400. Labor costs will be estimated at $50-$60, while the parts are priced between $140 and $350.

7. Bad trunk lock actuator: replace the actuator if it is bad

A trunk lock actuator plays a vital role to open a honda accord sport trunk lock. If the actuator is bad or is malfunctioning, the trunk will begin to be more difficult to open.

So, if the honda accord sport trunk fails to open, check the lock actuator and replace it if it is faulty. To do so, locate the actuator and remove the trunk liner. After that, disconnect the actuator cables and electrical connections.

Now remove the bolts that hold the actuator to the trunk and detach it. Once you remove the old actuator, install a new honda accord sport trunk lock actuator and do all the procedures reversely.
