My Iveco Daily won't lock anymore – what should I do?

If you can no longer lock your Iveco Daily, we strongly advise against leaving it parked unattended: in the event of a break-in, your insurance will not cover the damage if your vehicle has not been forced open. Consequently, even if your vehicle is parked on your own property, the risk remains very real. It is therefore urgent to have your Iveco Daily repaired so that you can continue to use it with peace of mind. 

Here is all the information you need to consider if your Iveco Daily no longer locks, along with some advice on putting together a replacement kit that can be used in any situation.

Is your Iveco Daily not locking? The first precautions to take!

It’s no secret: vans attract the attention of curious onlookers. If your Iveco Daily is well-maintained, it may be a target for theft. As vehicle break-ins are common, be vigilant. And before you look for the cause of this problem and find a solution, the first thing to do is to secure your vehicle and its load.

Whether they’re expert thieves or occasional opportunists, don’t tempt fate! Park near a safe spot, or better still in a garage, and empty your Iveco Daily completely. Of course, remove whatever’s in the back. Unload your cargo if necessary. Check that the handbrake is properly engaged.

Don’t forget what’s in the doors: maps, personal belongings… Remember to remove the documents from your Iveco Daily. If you no longer have the registration document, it will be even harder to prove the theft. Be vigilant.

If you’re not lucky enough to have a garage and find yourself unable to park your favourite car in a secure spot, plan ahead! Rent a space in a private garage or a secure car park. Don’t hesitate to inform the caretaker and park near their office. Just because the car park is monitored doesn’t mean you should neglect to empty your vehicle completely.

Understanding why my Iveco Daily won’t lock

Central locking is a complex system. It synchronises the opening and closing of all doors, including the Iveco Daily rear door hinge. A locking problem can have various causes.

• A mechanical fault 

When you press the car key, you are activating the central locking system. This system triggers a mechanical mechanism that allows the doors to open, but it also serves to start the engine and engage the handbrake. This mechanism operates the door locks uniformly. If you notice any difficulty, even slight, with the locking mechanism, the problem is likely to be mechanical in nature.

Three relays generally control the engine’s central locking system. If one of the relays no longer activates the system, it is faulty. Check that the wires are correctly connected to the back of the relay and that the terminals make good contact. Clean them if necessary. If everything appears to be in good condition, the switch itself will probably need replacing. There are three wires: one for locking, the second for unlocking, and the third provides the earth connection. Door switches are usually connected to the lock. They operate when the key is inserted. 

• A problem with the key

Insert the key into one of the locks. If you cannot open or close the door, your key may be damaged. Another indicator is that the Iveco Daily rear door switch is linked to the lock. If the switch does not work when you try to open a door by hand, you have probably found the root of the problem.

But if it only works when you press the button on your key, it is the locking mechanism that is not responding. It is highly likely that the batteries in your key have run out.

• A fuse problem

Central locking puts a strain on the electrical system. Consequently, damaged fuses make central locking impossible. This blocks the opening and closing system as there is no longer any power. It is highly likely that the fuses are the cause of this ‘power failure’. Having a kit with spare fuses to hand can prove very useful. 

Repairing my Iveco Daily that won’t lock

• What to do if there is a problem with the mechanism

With use, the engine mechanisms can seize up. To avoid damaging them, you need to plan ahead and look after them. So grease the door hinges with a cloth. Don’t forget the ratchet mechanism on each Iveco Daily rear door handle. Do the same with the locks.

• What to do if there is a problem with the key

To change the battery, simply remove the cover carefully. Insert a new battery, paying attention to its dimensions to avoid poor contact. If the key problems persist, return to your Iveco dealer with the vehicle documents.

• What to do if there is a fuse problem

To get your car’s central locking working again without having to take it to the garage, you’ll need to replace the central locking fuse. This is a relatively simple job. Locate the fuse box in your Iveco Daily. It is usually found next to the battery. To identify the central locking fuse, refer to the fuse box cover or your maintenance manual. Replace the faulty fuse with a new one using the pliers provided in the replacement kit.

If the central locking on your Iveco Daily is no longer working, you can sort out the problem yourself without necessarily taking your car to a garage. Are you looking for spare parts for an Iveco Daily or a replacement kit to fix the opening issue? Check out our online shop!
