The trunk of my Citroen Jumper 2 no longer closes

For obvious security reasons it is essential to have a safe that can be closed. Whether it does not close, you have to force it or the lock button is used repeatedly to open the trunk, all of these situations can become very stressful.
In this article, we want to try to help you in order to avoid having to go to the mechanic who would charge you dearly for the service, and also perhaps that you would have to wait a relatively long time for a potential appointment.
You will therefore discover the different steps to check where the fault comes from and how to carry out a repair which can be effective on your Citroen Jumper 2. Be careful, however, this does not of course replace the labor of a professional, but it might come in handy in a tricky situation.

Failures of the trunk of my Citroen Jumper 2

The trunk locks on a Citroen Jumper 2 are made up of mechanical and electronic components. They will wear out over time, especially on the mechanical part, leaving your vehicle with a latch that malfunctions or, in some cases, not at all.
If you notice any signs of the trunk latch failing, you may need to replace it or just adjust it. If you replace it, make sure it matches.
This article will deal with how to to repair a Citroen Jumper 2 trunk lock.
Be careful, this procedure will only work if the boot latch is still in good working order. If it’s already too damaged, chances are you have no choice but to buy one back.

Before starting, we want to give you a summary of the operation that will follow. Generally, what happens during these problems is the metallic female part which is supposed to hold the boot latch (male part) which no longer performs its function on your Citroen Jumper 2.
It is damaged or embarrassed, and therefore can no longer block the trunk via its latch. Often the mechanism is blocked by defective parts (rivets too old) that got inside and physically impair proper functioning. Think of it as if you wanted to lock a door with a key while there was key residue inside. It is likely that the mechanism is therefore blocked.
You will have to clean the entire mechanism and possibly repair a part or two.

Different steps to repair the trunk of your Citroen Jumper 2

1. The first thing to do is open the trunk and observe. You will have to remove the plastic part to be able to access the closing mechanism more easily.

Often this assembly will be covered with a plastic cover. This cover will need to be removed if the latch mounting bolts are not visible.

Once the plastic part is removed, you should perceive the mechanism with the latch.

2. Locate the lock strike. The lock strike is what holds the locking assembly together and allows it to have something to hold onto.

3. Check the components for wear. Once you gain access to both the lock assembly and the strike assembly, check for wear on both. The latch may have signs of wear and scratches on it.

Check if there is wear around the bolts that would mean the latch may have moved, or if there are any loose bolts. If any bolts are loose, do not tighten them yet. A displaced latch would therefore explain why you could no longer close the boot of your Citroen Jumper 2. If this was the case, it will have to be refocused so that it can retain the buckle of the boot and therefore block it.

4. Determine which direction to adjust the trunk lock. The trunk latch may have marks around the bolt holes. In the idea, the latch locks the trunk in a specific direction.

Repeated closing of the trunk may have moved the lock assembly. Even more if you tend to forcefully close it.

The wear marks show in which direction the trunk latch should be moved. The latch should be moved to the location of the original wear mark.

5. The strike plate may also show signs of wear, but these generally do not need to be adjusted. This part is a part of your lock which is not present on the safe, but on the hook of your safe. The strike is the part that receives the bolt, in order to engage the trunk closing.

Make sure that there are no parasitic pieces present in the mechanism. Clean everything as much as possible and replace the damaged screws.

6. Adjust the trunk latch. Loosen the trunk latch bolts. Then, gently slide the latch back to its original location.

Once the trunk latch is where it is supposed to be, tighten the bolts. Do not overtighten them.

7. Check the operation of the boot latch. Close the trunk and make sure the latch is working properly.

It may take a few moments for the trunk to open and close before it can function properly.
If necessary, repeat the trunk latch adjustment procedure until the latch closes properly.

8. Reinstall all removed panels. Once the lock has been properly adjusted and fully tested, reinstall the lock cover and strike cover if removed.


As you have noticed, wear and time are often responsible for the deterioration of mechanical parts. Usually when you clean everything and replace the really damaged small parts, or the pieces in the mechanism, you can get away with it for little money.

Nonetheless, for obvious security reasons, we recommend that you have this checked out by a professional fairly quickly to avoid finding yourself in a sticky situation with an open safe and valuables inside away from home. .
