Why putting a combination lock on luggage isn't as safe as you think

One of most travelers' first and foremost security concerns while planning for air travel is securing belongings. Combination locks are generally regarded as a simple, effective way to secure luggage.

They’re small, light, and apparently reliable — the ideal travel accessory . But are they as safe as they look? Recent insights show that combination locks might not be the foolproof barrier many travelers think they are.

In this article, we explore how combination locks are dangerous, not the infallible object we think they are, and what you can do to protect your luggage.

Why combination locks look secure

Combination locks, in particular (especially TSA-approved locks), are created to lock luggage shut while still allowing airport security staff to look inside without damaging the lock.

According to Master Lock, TSA-approved locks use a universal key system that allows authorized personnel to unlock and relock luggage during security screenings. Their convenience has also made them a popular choice for travelers.

Travelers often see combination locks as a deterrent to theft. They are small and relatively inexpensive, so they are naturally available everywhere and have cemented their identity as a default travel accessory.

But, as security experts and other frequent travelers note, these locks are not designed to be foolproof.

How do combination lock vulnerabilities affect whom?

Travelers

Combination locks are a staple for travelers who want to secure their belongings. But they can provide a false sense of security.

The locks on these bags are not as secure as they appear — at least not according to a viral video in which an airport security employee opened the lock on such a bag with two large paperclips, as stated by Unilad.

Airlines

Security breaches of this nature affect airlines, too. Airlines take much of the blame when passengers have their belongings stolen, suffering reputational damage and legal claims. Such incidents expose weaknesses in the systems for handling bags and the more extensive airport security apparatus.

Airport security personnel

Locks that the TSA approves are meant to facilitate inspections by airport staff. However, TSA master keys have made their way onto the internet, which means that all TSA-approved locks are insecure, as noted by Briggs & Riley. As a result, this pandemic of vulnerability has posed new problems for airport security teams and left travelers more at risk than ever before.

Combination locks: what are they poor at?

Easily bypassed

Combination locks are surprisingly easy to tamper with. As a Reddit thread about luggage security explains, many combination locks can be opened with only simple tools or by feeling the subtle clicks in the lock mechanism as you turn the dial.

Videos and tutorials available online even show step-by-step instructions for picking open these locks, making them unreliable for serious security.

Physical vulnerabilities

Typically, combination locks are not built for heavy-duty. According to TravelPro, sturdy locks sometimes fail because determined thieves simply ignore them altogether, cutting through the zipper of the suitcase or the lock itself. Most combination locks are lightweight and can not withstand brute force, leaving them vulnerable to criminals.

TSA-approved lock risks

TSA-approved locks are supposed to ease the security check process but have major limitations. The universal keys employed by TSA agents to access these locks have been leaked and are readily available online, as Briggs & Riley explains.

With a 3D printer and access to these essential designs, people can easily open TSA-approved locks and completely compromise luggage.

Where is it most dangerous for travelers?

Luggage security varies greatly depending on where and how it is handled. Certain environments and scenarios make combination locks vulnerable.

Airports

Airports are a target for luggage tampering. Baggage handling areas, which passengers typically do not see and cannot access, offer opportunities for unscrupulous individuals to access suitcases.

As Unilad mentioned, thieves are often drawn to luggage with visible carcass locks, as they are taken as an indication that the bags hold high-value contents. Ironically, locks can also make luggage a more appealing target.

Transit hubs

Significant transit crossroads like New York-JFK, Dubai, or London Heathrow are perilous, given the number of passengers and bags moving daily.

The intense foot traffic and busy surroundings also make it practically impossible to keep an eye on every piece of luggage, which creates opportunities for thieves.

High-crime regions

Luggage theft is even more common in places with higher crime rates or less rigorous airport security. Thieves in these areas typically have the tools to gain access to locked suitcases quickly and quietly.

Looking for an extra veil of safety? Try these!

Cable ties - a potential solution

Cable ties are a cheap, tamper-evident solution. Though they don’t necessarily stop theft from happening, they may deter opportunistic thieves and provide a sign of tampering.

Cable ties are more than adequate for travelers seeking a cheap and quick solution to securing their luggage, as per TravelPro.

Luggage straps

Integrated locking mechanisms in luggage straps offer an extra level of security. These mechanisms also make it more difficult for thieves to access a bag's contents and secure zippers that might otherwise be pried open.

Hard-shell luggage

For added protection, high-quality hard-shell luggage also makes a significant investment. These are more resistant to cutting and puncturing than their soft-shell counterparts, making them a better option for lockable belongings.

Smart luggage

Tech-loving travelers may find that smart luggage with built-in security features such as GPS tracking and Bluetooth-enabled locks can help ease their minds. Though costlier, they are much more powerful and secure.

Some tips on luggage security

Travelers can mitigate their risk of being inside a hotel with a thief by doing the following:

• Do you have valuables in a checked bag? Pack valuables — such as jewelry, electronics, and important documents — in your carry-on. Checked bags are at a higher risk of tampering and theft.
• Use tamper-evident solutions: opt for alternatives like cable ties or tamper-evident seals to warn you of possible breaches.
• Choose inconspicuous luggage: choose simple, nondescript suitcases to avoid drawing attention. Branded or brightly colored luggage may identify you as a target.
• Invest in travel insurance: Travel insurance offers complete financial protection against theft or loss.
• Label your luggage clearly.
• Clear labels with your name and contact details: It can help prevent accidental loss or theft.
• Stay vigilant
• Keep an eye on your luggage while passing through transit whenever possible, especially in crowded situations such as baggage claim.

Your luggage matters when it comes to keeping your things secure.

For example, hard-shell luggage offers more resistance to tampering or puncturing, and built-in locks mean no external padlocks can be broken. Brands that specifically focus on travel security often implement anti-theft zippers, reinforced seams, and lockable compartments into their designs, providing true peace of mind when traveling.

Smart luggage, which comes with advanced locking mechanisms and GPS trackers, is also a great pick for those who value safety and convenient transportation. Here is a list of some of the best bag types for better-locking security:

• Hard-shell suitcases with integrated TSA-approved locks: These are more cut- and tamper-resistant, so they are best for those who travel frequently.
• Anti-theft backpacks and bags: Made with slash-resistant material, lockable zippers, and RFID-blocking compartments to keep valuables safe.
• Smart luggage — When tech-savvy travelers want all the features, such as biometric locks, GPS tracking, and the ability to lock luggage remotely via a mobile app.
• The expandable suitcase comes with a double zipper design to prevent forced entry.
• Duffel bags with hidden compartments: These bags have hidden compartments that don’t come in handy for everyone, but they provide more security for your valuables!

No lock is entirely safe

Combination locks might seem like a way to secure your luggage, but they offer slight protection from theft. Their vulnerabilities (from easily being picked to the risks of TSA-approved locks) leave travelers vulnerable.

If you are not relying only on these locks, you can use cable ties, luggage straps, or hard-shell suitcases to ensure better security for your luggage.

Be aware of the limitations of combination locks. The first step to making more intelligent travel choices is to know their limitations. However, by using best practices and considering alternative solutions, you can mitigate the risk of theft so that you can rest easy on your adventures.
