Using Lock Picking Tools

Depending on the model of your roof box, this process may either be easy or very tedious. Some roof boxes feature extra security measures, which may make picking the lock(s) impossible. Picking a lock often requires a certain amount of technical knowledge, which is not too complex for the layman.

There are several lock-picking concepts and techniques, ranging from basic to quite complex. Basic lock-picking skills can open many types of locks when done correctly. Picking a basic lock requires such tools as hooks, rakes, and tensioning tools.

You can find these tools in local hardware stores. It is also very likely that the locksmith in your neighborhood has them. You should note here that in most states, owning these tools is only considered a crime if they are used illegally. If you have no intention of breaking the law and can prove that, it is not an issue.

The actual lock-picking process will depend on the type of lock on your model. Once you establish the type of lock, you can do a little research to find out how best to pick it using the tools we have mentioned.

Take It to A Locksmith

If you are in a place where you can easily access a locksmith, then this will be the best alternative. Locksmiths are well-versed in the methods of opening locks or making a replacement key. So, uninstall the key-less box from the roof rack and bring it to the locksmith.

Each key usually has a code that is also indicated on the lock. So, to replace a key, the locksmith has to use this code. The code is usually written as an uppercase letter followed by 3 digits. It ensures that the locksmith can create a replica of the key, which will be used to open your roof box.

Furthermore, this process only takes a few minutes, which is convenient as you can get back to your activities within a short while. Still, if you would not like to get extra keys, the locksmith may also pick the lock for you. This would be very easy for a trained locksmith and, therefore, opening your box would be a walk in the park.

The locksmith will require specialist tools if the model features a high-security lock. In the event that the lock is already damaged, it may be impossible for them to pick it, thereby necessitating a different approach, such as breaking the box or just getting a new one.

Drill The Lock

Some boxes, such as the Thule box, are made of a hard-shell material. This material is watertight and features high-standard security measures to keep your box safe. Thus, if you misplaced it, the only solution would be to drill out the lock barrel and later replace it with a new one. As such, you would need a power drill with metal bits to remove the lock. You will also have to get replacement key barrels and locks. To start, you will need to have the box in an accessible place, so take it off the vehicle’s roof and place it in a flat working area. Then, remove the lock-cap to expose the keyhole and lock barrel. After that, place the drill bit onto the dead-center of the barrel and take out the lock cylinder with great care. Make sure to drill in straight so as not to damage the plastic edges of your box. Once you have drilled all the way to the other end, proceed to disengage the lock mechanisms. At this point, you can pull out the lock barrel and open your box to access your valuables. You will then proceed to install the new lock as per the installation instructions of your specific box model.

Contact The Manufacturer

This option may very well be the last resort as it is often a lengthy process. If you are in no hurry to open your cargo box, this option will be viable. Contacting the manufacturer is the safest way to deal with a missing key. It also has its perks.

For one, you will not go to the extent of causing any damage to your cargo box or incurring extra costs. The manufacturer will take up the responsibility of fixing the problem and deliver the box back in excellent condition.

In some instances, they will provide you with replacement keys free of charge. You would have to provide the code as encrypted on the cargo box’ key lock for this to happen. Since not all locks have this number printed on them, it is wise to note down the  code printed on the key whenever you get a new cargo box.

How to Open a Roof Box Without Keys: Alternative Methods

Using a Paperclip

First, locate the keyhole on the top of the roof rack, usually at the front near the handle on the t-bar. Gently insert the paper clip into the keyhole as though it is the rubber-coated metal key that normally opens the lock.

Once inserted, apply gentle leverage and pressure on the paper clip. You’ll want to wiggle it slightly clockwise or counter-clockwise inside the lock cylinder. With some patience and manipulation, the paper clip may be able to release the lock mechanism inside.

It’s important to use care when doing this so as not to damage any parts. The goal is to get the lock to disengage so that the roof rack will open. You may find that gently urging the wave covering the lock cylinder also helps remove it to access the lock core better with the paper clip.

If done correctly, the roof rack should unlock and you’ll be able to open it to access your items.

Using a Credit Card

If a paper clip does not work, you can try using a credit card as an alternative to open the roof rack lock. To do this, locate the bolt that secures the lock on the front of the roof rack near the handle on the t-bar.

Take a credit card or hotel key card and gently insert it between the bolt and the roof rack. You may need to use a philips head screwdriver to help urge the wave covering the bolt area. With patience, wiggle the card from side to side while applying a bit of pressure to see if it can release the bolt.

This method works by using the card as a lever to disengage the bolt holding the lock in place. It allows you to take off the top piece covering the lock core without damaging the rack. If done carefully, the rack will open once the bolt is removed.

However, it’s important to note that this may not work for every brand or model of Thule roof rack. Additionally, using too much force on the credit card risks breaking it or potentially harming the lock cylinder.

Brute Force Method

If alternative methods like a paper clip or credit card have failed, a brute force technique may open the roof rack without keys, but requires caution. One way is to use physical leverage and pressure on the lock cylinder or bolt area with tools.

A flathead screwdriver or philips head screwdriver can be inserted and hit with force in an attempt to break or pry open the lock mechanism. This method aims to compromise the lock’s secure attachment on the roof rack. It may release the latch allowing the roof rack to open.

Can You Duplicate Your Roof Box Key?

If the key has a specific code or number, you may be able to order a replacement directly from the manufacturer or a licensed dealer. In some cases, a locksmith may be able to create a new one for your roof box, but this can be more expensive than ordering a replacement from the manufacturer.

Can opening a box without a key damage the box or void its warranty?

Opening a box without a key can potentially damage the box or lock, especially if alternative methods are used. The brute force method, in particular, can cause significant damage to the box and may void the manufacturer’s warranty. If you must, it is recommended to use the guaranteed methods first, such as contacting the manufacturer or visiting a locksmith, to avoid damaging the box or lock. Always check the manufacturer’s warranty policy before attempting to open a box without a key to determine if any damage caused by alternative methods will void the warranty.

Final Thoughts

In summary, there are a few options to consider if you find yourself locked out of your Thule roof rack without keys. While alternative methods like using paper clips or credit cards near the lock offer a possible solution, they are not guaranteed and risk damage over time if done improperly.

The best approaches involve having the lock professionally picked by a locksmith, who can often open it without compromising the lock core. Otherwise, contacting the roof rack manufacturer allows them to cut a replacement set of keys or provide a re-key code to regain authorized access.

More forceful methods should really only be an absolute last resort, as they risk seriously harming the roof rack or voiding the warranty. It is always preferable to keep the original keys that came with your factory-installed Thule roof rack in a safe yet accessible location to avoid this situation in the first place.

With the right precautions, you can feel confident knowing your Thule roof rack and contents will remain securely accessible whenever needed using the intended key. Hopefully this overview provides a solution should keys ever get misplaced, but the easiest approach is to simply keep the key safe from the start.
