Replacing a locking system: costs in 2026 at a glance

Many buildings still rely on traditional, mechanical locking systems. The advantages of an electronic locking system are however compelling enough that more and more companies as well as private households are considering an upgrade. This article shows what replacing a locking system realistically costs in 2026, which factors influence the price, and how to save money in the long run.

‍

When should a locking system be replaced?

Replacing a locking system is worthwhile above all after a lost key, frequent staff turnover, outdated technology, or a break-in. In these cases, either security drops or administrative effort increases noticeably.

Typical reasons for switching include:

•  Lost or stolen keys: With a mechanical locking system, a lost key often means replacing the entire system, including all cylinders and keys. The article Lost key: Replacing locking system shows how expensive this can get.

•  Frequent staff turnover: In office buildings with high turnover, managing physical keys quickly becomes confusing and error-prone.

•  Outdated or worn technology: After many years in use, the reliability of mechanical cylinders declines.

•  Break-in or security incident: After a break-in, it is advisable to review, and often replace, the affected locking system.

•  Renovation or expansion: New doors or additional building sections require an adjustment of the existing locking plan.

Cost factors: how much does replacing a locking system cost?

Replacing a locking system costs, depending on building size, number of doors, and chosen system, anywhere from a few hundred euros for a single cylinder to several tens of thousands of euros for a complete corporate system.

An electronic locking system offers a range of advantages. It is convenient, provides a high level of security, and can be configured flexibly. While electronic locking systems are generally considered more expensive than traditional systems, these costs are quickly put into perspective by their many benefits.

A particular advantage is security in the event of a lost or stolen key. While a traditional locking system requires the entire system to be replaced, this is not necessary with the electronic variant. This saves significant costs in the event of a replacement. Users should therefore focus on the substantial savings potential.

Costs for an electronic locking system vary depending on the manufacturer and features. Anyone looking to replace their system should expect several cost items. As with any purchase, both installation costs and follow-up costs are relevant when switching. To determine the total cost, both cost items are added together.

The following cost factors should be considered when replacing a locking system:

•  Number of locks required: How many doors should be equipped with a lock and included in the system?

•  Installation: How complex is the installation of the locking system? Is specific technical equipment a prerequisite?

•  Security: The higher the quality, the more secure a system is. However, high quality usually comes with higher costs. In any case, you should look for high security standards and special encryption, such as those used by BlueID.

•  Access medium: Electronic locking systems do not use traditional keys. Instead, alternative access media such as key cards, RFID key fobs, fingerprint sensors, or transponders are used. Costs vary depending on how many electronic keys are required.

•  Maintenance and administration: Electronic locking systems are particularly advantageous because they can be managed via a digital key management platform. A monthly fee is often charged for this. This gives you access to all permissions at any time and lets you adjust them flexibly.

Material costs per locking cylinder

Material costs differ significantly between mechanical and electronic systems. A simple mechanical cylinder typically costs between 80 and 150 euros per door. An electronic knob cylinder from BlueID with NFC and Bluetooth technology is available from 400 euros per door, but covers both the inside and outside of the door and requires no replacement in the event of a lost key.

Installation costs

Installation costs depend heavily on the chosen system. Battery-powered electronic cylinders, like those used by BlueID, require no wiring and can usually be installed in existing doors without structural changes. This significantly reduces installation effort compared to wired systems, noticeably lowering total costs for companies.

Ongoing costs: maintenance, software, and batteries

In addition to acquisition costs, electronic locking systems incur ongoing costs. These include the monthly fee for management software and battery replacement, which modern systems require on average only every two years. In return, costs for reordering keys and replacing them after loss are eliminated entirely.

Cost example: what does a locking system cost by building type?

Costs for a locking system vary greatly by building type and number of users. The following overview shows typical benchmark figures for a replacement. These figures are estimates and do not replace an individual quote.

Costs for private households and single-family homes

For a single-family home with few doors, an electronic locking system typically costs between 500 and 3,000 euros, depending on the number of cylinders and desired functionality.

Costs for multi-family buildings

For a multi-tenant building with several units, costs rise with the number of residential units and shared doors, such as the main entrance, basement, or garage. Realistic costs here range between 2,000 and 8,000 euros for the complete system.

Costs for companies and office buildings

In companies with many doors and employees, cost variation is greatest, ranging from around 1,000 euros for small offices to several tens of thousands of euros for large building complexes with hundreds of access points. BlueID offers tiered packages for this, from the Starter model at a one-time 50 euros plus 1 euro per lock per month, up to the Integrator package for large portfolios with 100 included locks.

Cost comparison: purely mechanical or digital locking system?

Costs between purely mechanical and digital locking systems vary. Traditional locking systems are usually cheaper. The following cost factors must be considered:

•  Number of locking cylinders

•  Security level

•  Number of keys

•  Master key system or keyed-alike configuration

Ongoing costs also differ between mechanical and electronic variants. Maintenance contracts are common in both cases. With electronic locking systems, however, software-based management is added.

As a rule, the additional cost of an electronic locking system is worthwhile. After all, you benefit from significant advantages and save money in the event of a lost key. 

Electronic locking system: What benefits justify the higher cost?

An electronic locking system costs more to purchase than a mechanical system, but offers clear advantages in security, flexibility, and management.

Key benefits include:

•  Security to recognized standards: BlueID components are VDE-certified and meet requirements such as EN 179 for emergency exits and IP66 for outdoor weather resistance.

•  Central management: Permissions can be granted, adjusted, or revoked in real time via a cloud platform, without any key exchange.

•  Offline functionality: BlueID locks work reliably even without a permanent internet connection.

•  Scalability: New doors or users can be added at any time, which is especially relevant for growing companies and PropTech projects.

•  Traceability: Access logs make it easier to meet security and compliance requirements.

Do costs for replacing a locking system vary between companies and private individuals?

Anyone looking to replace a locking system and switch to an electronic variant has certain costs to expect. But do these vary between companies and private individuals?

Basically, the cost components are the same. However, the scope of the locking system usually differs significantly. While private individuals generally need only a few digital locks, a company requires a much larger number. In addition, more people enter and exit a company building, meaning more digital keys must be issued and managed.

For this reason alone, the cost of replacing a locking system is usually higher in a business setting than in a private household.

Step by step: how replacing a locking system works

Replacing a locking system generally follows a clearly structured process:

•  Needs analysis and locking plan: First, the number of doors, users, and access levels required is determined.

•  Offer and configuration: Using the BlueID locking system configurator, the right solution can be put together in just a few steps.

•  Hardware delivery: Cylinders, door fittings, or wall readers are shipped.

•  Installation: Since BlueID components are battery-powered, complex wiring is not required in most cases.
