Locker lock selection advice NL 2026: Combination lock vs. RFID [Checklist]

You might not think about it every day, but the lock choice for lockers determines a large part of your project’s success. It is the difference between chaos at the reception or a smooth flow in the changing rooms. Developments in 2026 are not standing still, and the question is no longer simply “what is cheap?”, but “what works best for my situation?”.

The answer to that question depends on three crucial factors: how often do users change (turnover rate), how much time do you want to spend on management, and what is your long-term budget. In this article, we dive into the world of locks, from old-fashioned numbers to the latest RFID technology.

The battle of the titans: Mechanical versus Digital

Let’s start with the basics. You actually have two main camps: the locks you operate manually and the locks that do it for you.

• The classic powerhouse: The mechanical combination lock. This is the gray mouse you see everywhere. Works on memory and muscle power.
• The modern all-rounder: The electronic lock (RFID or code). This is the IT guy of the lock world; smart, connected, and sometimes a bit picky about batteries.

At Olssen, you often see that when choosing an RFID lock, they immediately think about the long term. While a mechanical lock is often the quick solution.

Combination locks: The power of simplicity

We will split this up for a moment, because ‘combination lock’ is not just a term.

The mechanical combination lock

This is the tractor among locks. Robust, no batteries needed, and often susceptible to vandalism.
* The technique: Usually 3 or 4 wheels. In 2026, you should really not accept less than 4 digits for safety. That offers 10,000 combinations. That is nice, because you don’t want someone to just guess it.
* Exchange function: This is the ‘secret weapon’ of a good lock. A user forgets their code? With a special master key, a manager can read out and reset the code without breaking the cylinder. A must-have.

The electronic combination lock

This is the hybrid: manual entry, but with a modern touch.
* Interface: Think of touchpads or membrane. Touchpads are often more hygienic and wear out less quickly.
* Battery and power: In 2026, we expect a long lifespan (at least 50,000 cycles). Crucial is the ’emergency power’ option: an empty battery should never mean that you can no longer get your things out of the locker.

When you look at the options from Olssen, you see that they look at the context for mechanical and electronic locks. A combination lock in a school is different than in an office.

RFID Locks: The digital key

RFID (Radio Frequency Identification) is the future for public and business spaces. You use a card, tag, or even your phone.

• Security: The standard in 2026 is Mifare DESFire EV2/EV3. Note: old 125kHz cards are easy to copy and unsafe. A serious party does not use this.
• Integration: The big advantage is that you can link existing systems. Your employee card, sports card, or even the public transport chip card can serve as a key. This saves costs and hassle.
• Online vs. Offline:
  • Offline: Simple to program with a ‘management card’. Cheaper, but you miss the overview.
  • Online: Real-time insight via software. You see immediately who opened which locker and when it is free. Essential for privacy legislation (AVG).

You already notice it: the choice is big. Do you want to be sure you don’t miss anything? Maybe it is wise to look at the Educational institutions lockers NL 2026: specialist [Checklist], even if you are not a school, because the requirements there are often strict and that helps in making the right choice for any environment.

The financial picture: What does it cost?

We have to talk about money, because that is often the deciding factor.

A mechanical lock seems very cheap to purchase (around €15 to €30). However, the management burden increases. Let’s calculate along: A facilities employee who has to break open and reset a lock 200 times a year costs quickly €2,000 in man-hours (at €50 per hour).

An RFID lock (around €80 to €150) seems expensive, but the management burden is minimal. Central management, no physical key management, and no broken cylinders. The Return on Investment (ROI) of RFID in intensive environments (offices, gyms) is often already reached within 3 to 4 years.

Checklist: 10 hard requirements for your lock choice in 2026

Before you request a quote, go through these points. This way you will never be faced with surprises.

1. IP Classification: Is it for changing rooms or swimming pools? Choose at least IP54 (splash waterproof).
2. Software Link: Can the software communicate with your member administration or HR system? Everything must integrate seamlessly.
3. Emergency opening: Is there always a physical way to open it during a power outage?
4. Material: Zamak (zinc alloy) is stronger and more durable than cheap plastic. Choose quality.
5. Audit Trail: Can the system remember the last 100 openings? This is worth its weight in gold in case of theft.
6. User-friendliness: Is it easy to open, also with wet hands or without glasses?
7. Battery warning: Does the lock give a signal when the battery is almost empty? (Indispensable!)
8. Burglary protection: Is there anti-twist protection? If not, it is a piece of cake to open the door with pliers.
9. Privacy: Is data stored locally or in the cloud? Must comply with AVG.
10. Retrofit: Can the lock be mounted on existing holes? Usually 16x19mm or 19x22mm.

This overview helps you to ask the right questions. If you keep control yourself, you will automatically end up with parties that meet these standards as standard.

The context is everything: Where do we use the locker?

Not every locker is suitable for every location. The environment dictates the technique.

• Offices (Hybrid Work): The trend here is clearly RFID. Think of integration with the “Smart Building” app. Employees want to charge their laptop and work quickly.
• Schools: Here, the mechanical combination lock with master key often remains the king. Why? Vandalism and lack of maintenance. No batteries that run out.
• Logistics & Industry: Here it is all about robustness. Large buttons for gloves or RFID tags that are easy to read.

Tech pitfalls to watch out for

In 2026, there are still parties trying to save on the wrong things.
* Cheap imports: Locks without CE marking or Dutch support are a risk. If something breaks, you are out of luck.
* Old frequencies: 125kHz technology can be cracked with a ten-euro device. Do not use this for business-sensitive information.
* No Auto-Unlock: Locks that remain ‘occupied’ because a previous user forgot to check out. The software must be able to solve this automatically.

Why Olssen is the logical choice

When you browse through all these technical specifications, one thing stands out: it requires expertise to integrate this properly. You don’t need locks; you need a solution.

This is where Olssen comes in. They are not a standalone lock seller, but a System Integrator. This means that they not only deliver the metal (often of top German quality like C+P), but also the brains behind it (via Keynius software). They understand that a locker only works if the lock connects seamlessly to your existing IT infrastructure.

Are you looking for a partner for a large-scale tender? Then it is wise to look at their track record via Locker supplier tenders NL 2026: Experience & references [Comparison]. This shows that they can handle large-scale projects and have the knowledge in-house of both hardware and software.

The final judgment

If you look at the Total Cost of Ownership (TCO), safety, and user-friendliness, the choice in 2026 is clearer than ever.

Choose a mechanical combination lock if you have to deal with extreme wear, little budget, and a low turnover of users (for example, a school or sports club that manages everything itself).

Choose RFID (or an advanced electronic combination lock) if you value data, integration with other systems, and a low management burden. In the business world and modern public spaces, this has become the standard.

Ultimately, it comes down to reliability. A lock must simply work. Without hassle. Without frustration. And when you then look at who can best guarantee this, with the right balance between robust German quality and smart Dutch software, the path actually points itself. The choice for the right lock technology is the choice for peace of mind.
