Why modernizing your access control system is indispensable

The reasons for modernizing existing access control systems are manifold, ranging from acute security concerns to economic considerations. Outdated systems are often vulnerable to tampering, offer inadequate logging, and considerably complicate the management of access authorisations. This leads not only to potential security gaps but also to increased administrative effort and associated costs. Digital transformation and the growing interconnection of building technology also require an integration that older systems simply cannot deliver. A further decisive factor is the constantly evolving threat landscape: cyberattacks and physical break-ins are becoming more complex, meaning the protective mechanisms of access control systems must be continuously adapted. Without modernization, companies risk falling behind current security standards and exposing themselves to unnecessary dangers. Investing in a modern access control system is therefore an investment in the future security and operational resilience of the entire company. According to a report on wireless access control for 2025, wireless systems have overtaken wired solutions for the first time, underscoring the need to keep pace with technological developments.

Challenges and risks of outdated access control systems

Outdated access control systems bring a range of significant challenges and risks that go beyond mere inefficiency. One of the biggest problems is inadequate security. Older technologies are often easier to circumvent, whether by copying mechanical keys or reading unencrypted transponders. This not only creates entry points for unauthorised access but also makes it harder to trace events without gaps, which can have serious consequences in the event of a claim. High operating costs are another characteristic of outdated systems. Managing physical keys is time-consuming and expensive, especially in the event of loss, which often necessitates replacing entire locking systems. In addition, older systems lack the scalability and flexibility to adapt to growing staff numbers or changing building structures. This leads to an undesirable dependency on a manufacturer, since spare parts or software updates can often only be obtained from a single provider, meaning high costs and low innovation capacity in the long term. The lack of integration capability with other security systems, such as fire alarm systems or video surveillance, also prevents a holistic security strategy and complicates the central management of security events.

The market for access control systems is developing rapidly, driven by digitalisation and the desire for greater security and user-friendliness. In 2026, several key technologies and trends are shaping the modernization of access control systems. Biometric procedures, such as fingerprint or facial recognition, are becoming increasingly important, as they offer a high degree of security and comfort by eliminating the need for physical identification tokens. Mobile access solutions, which use smartphones as digital keys, are also on the rise. A 2025 report shows that the use of fully mobile credential environments was confirmed by 17 percent of respondents, more than three times as many as in 2023. Cloud-based access control systems offer flexible, scalable and often more cost-effective management, since they reduce local infrastructure and enable remote access. Artificial intelligence (AI) and machine learning are used to analyse behavioural patterns, detect anomalies and minimise false alarms, considerably increasing the efficiency of security measures. In addition, contactless access solutions, originally driven by the pandemic, have become a necessity for efficiency and hygiene. These technologies enable seamless integration into existing building management systems, creating an intelligent, networked security architecture.

Our goal is to deliver you a solution that is not only technically mature but also economically optimal and maintainable in the long term, by selecting certified installers and objectively evaluating their services.

Modernizing an access control system is inseparably linked to compliance with relevant legal provisions and technical standards. In particular, the General Data Protection Regulation (GDPR) places high demands on the processing of personal data, which inevitably arises with access control systems. This concerns the collection, storage and use of identification features and access logs. Companies must ensure that the planned systems meet the principles of data minimisation, purpose limitation and transparency, and that the rights of the data subjects are preserved. In addition, technical standards such as DIN EN 60839-11-1 are of central importance. This standard sets out the minimum functionality, performance requirements and test methods for electronic access control systems and their components. In addition, VdS guidelines, such as VdS 2358 for requirements and VdS 2367 for the planning and installation of access control systems, provide valuable guidance for proper implementation. The guidelines of the German Federal Office for Information Security (BSI) on identity and authorisation management must also be taken into account. Legally compliant, standard-compliant planning is not only a statutory duty but also a decisive factor for the acceptance and long-term success of the modernised system. Through its expertise, PLANATEL® ensures that all relevant requirements are integrated into the planning from the outset.

Economic aspects and return on investment (ROI) of a modernization

The decision to modernize an access control system is not only a security question but also a strategic investment that should deliver a clear return on investment (ROI). The initial costs of the modernization can be more than offset by long-term savings and efficiency gains. A key factor is the reduction of operating costs: modern, digital systems eliminate the effort of managing physical keys, the loss of which can necessitate expensive replacement of locking systems. Automating access processes also saves valuable working time and minimises sources of error. Precise logging of all access events increases transparency, which facilitates investigation in the event of a claim and reduces potential liability risks. Improved security also minimises the risk of theft, vandalism or espionage, the financial and reputational consequences of which can be considerable. Modern systems are also more scalable and flexible, which increases investment protection, since they can more easily adapt to future requirements and avoid dependency on a manufacturer. The European market for access control hardware is estimated at USD 2.63 billion in 2026 and is expected to reach a value of USD 3.54 billion by 2031, representing annual growth of 6.12% and underscoring the growing willingness to invest in this area. A detailed cost-benefit analysis, as prepared by PLANATEL®, is decisive for transparently presenting the economic added value of the modernization.

Integration options and synergies with other systems

Modern access control systems only unfold their full potential through seamless integration with other building management and security systems. This networking creates synergies that go beyond mere access regulation and enable a holistic security strategy. Central integration can, for example, link access control with fire alarm systems (BMA), to automatically release escape routes in the event of fire and ease access for rescue personnel. Coupling with intrusion detection systems (EMA) is equally sensible, to immediately trigger an alarm and secure the relevant areas in the event of unauthorised access. Video surveillance systems can be connected to access control, to automatically activate the relevant cameras during access attempts and visually document events. Integration with time-recording systems is also a common use case, simplifying personnel administration and increasing efficiency. Central control and monitoring of all systems via a shared platform optimises processes, shortens response times, and reduces administrative effort. PLANATEL® plans such complex integration scenarios on a manufacturer-neutral basis and ensures that the interfaces function smoothly and that the overall solution meets the highest requirements for security and functionality. Creating an intelligent, networked security architecture is a central trend in security technology in 2026.
