Guide to keypad access control systems and door locks

What is an access control keypad system?

Keypad access control systems typically consist of credential readers installed in selected entry points. The digital combination door lock device is a type of commercial door lock featuring an interface with numbered buttons or a touchscreen access control panel. To gain access to a property, users must input a pre-approved series of numbers or a PIN code into the keypad system.

By operating a door access keypad, property owners are able to allow access to tenants, staff and guests while securing select locations from unauthorized persons and potential threats.

The scope of an installed keypad system will depend on the use case. Standalone single-access keypad readers or PIN door locks can be utilized to secure private properties and homes from intruders, while integrated keypad access system networks can be developed for commercial enterprises with multiple entrances to secure.

How does a keypad access control system work? 

Keypad access control systems are used to replace traditional key-based locks with a more reliable and traceable method of controlling access. Rather than carrying physical access credentials that can be easily lost, misplaced or copied, users simply input a PIN code into the commercial keypad lock to gain building access.

All commercial door keypad lock devices require a dedicated power source, with some modern systems configured to communicate using an Internet connection, allowing admins to monitor, adjust and manage the network remotely via smart devices or computers.

When operating an IP or cloud-based keypad reader security system, admins can update directories, assign new PIN codes and edit access permissions from a web-based dashboard, while local keypad control systems must be manually updated and maintained by on-site security staff and IT teams.

Where to install door access control keypads

As access control keypad devices are generally small in size, these entry point solutions can be utilized to secure most doors and gates. 

Keypad commercial door lock systems are typically used to secure: 

• Building entrances and exits
• Gated community access points
• Private residential areas
• Storage closets and staff rooms
• Garages
• Warehouses
• Office complexes
• Self-storage units 

Depending on the intended use of an installed keypad combination door lock, property owners should seek out devices with specific features to ensure smooth operation and optimize security. For example, exterior keypad door lock readers used to secure outdoor locations should be waterproof and weather-resistant with an IP65 enclosure rating.

Types of commercial keypad readers and combination door locks

Door access control keypad systems come in a wide range, with certain types being more cost-effective for particular use cases.

Additionally, business and property owners must consider where individual devices are to be installed. An exterior keypad door lock used to secure an outdoor entry point will have different requirements than a storage closet combination door lock, both in terms of hardware design and security features.

Further considerations include the type of locking mechanism, whether the system would benefit from Internet connectivity and how security teams intend to integrate existing technology with newly installed readers. Below are four common keypad lock types:

The pros and cons of keypad door access control systems

As with any commercial access control system or building security device, there are benefits and drawbacks to the installation and operation of a commercial code door lock or keypad access system. The positives of a keypad door access system generally involve improved convenience and a relatively cost-effective approach to building security. However, a keypad door access control system is not always the most secure way to control access.

Pros:

• Cost-effective — Unlike key card or Radio-Frequency Identification (RFID) fob access systems, business and property owners will not be required to purchase and manage sets of physical credentials when operating a commercial PIN door lock, helping to reduce overall operational costs.
• Simple operation — Staff, tenants and guests will not be required to carry physical keys or credentials, which can easily be lost or stolen. Instead, simple codes can be distributed via encrypted email with admins able to adjust active codes, should a suspected breach occur.
• Multi-layered security — Keypad access readers can be integrated with existing or newly installed security devices to develop MFA. For example, access to high-security areas may be granted using biometric readers that require a PIN code to engage the scanner.
• Versatility — Security teams can issue multiple PIN codes used to secure different areas of the property, with options to easily change these codes if a breach is suspected. This removes the need for employees or residents to carry multiple sets of keys on a day-to-day basis.

Cons:

• Administrative issues — When operating a keypad access system, security and IT staff must be prepared to provide ongoing technical support to address common issues, such as forgotten codes or faulty hardware. This often requires on-site troubleshooting to resolve.
• Frequent maintenance — PIN codes must be reset regularly to reduce the likelihood of security breaches, and batteries may need to be replaced in some styles of keypad readers. For larger deployments featuring multiple devices, this task can be both time- and labor-intensive.
• Security exploits — As PIN codes are not tied to individual users and are shared by all residents of the property, it can be hard for security teams to ensure that codes are not learned by unauthorized users. Also, physical indicators like worn-down buttons can allow intruders to guess active codes. For these reasons, many security teams choose to operate keypad access devices alongside additional access control security systems.

Considerations for installing keypad access systems

When installing keypad access systems across a facility, several key factors must be considered to create a robust, user-friendly solution. These key considerations can be split into two categories:

Pre-installation

• Determine requirements: Assess the facility to consider which type of keypad access system is required, the chosen doors, potential weather conditions if installed on exterior doors, traffic flow and user access permissions.
• Budget: Consider the total cost of the installation. Take note to factor in the cost of hiring a third party to carry out the access control installation and potential maintenance costs.
• Choosing the right solution: Consider whether the chosen keypad access system fits with the door frames and integrates with other security systems on the premises, including video security.

Installation

• Third-party support: Consider hiring a professional installer to ensure the installation is correct and complies with regulatory requirements.
• Wiring: If installing a wired solution, consider the wiring plan to ensure it complies with the manufacturer’s instructions.
• Hardware: When installing the keypad access control system, consider the orientation of the keypad, its height and whether it is in a user-friendly location

Key features to look for in an access control keypad system

Selecting the most appropriate and effective keypad access control system will largely depend on the unique nature of the property and the level of security required. The following are key features all organizations should look for in an effective access control keypad system: 

• Internet connectivity and mobile access: Choosing a keypad access system equipped with Internet connectivity and mobile credentials features allows security teams to issue temporary credentials and PIN codes to visitors via a secure mobile app, allowing for easily monitored access without requiring in-person visitor management.
• Multi-factor authentication: Seek a solution with multi-factor authentication (MFA) capabilities to enhance security. MFA is the use of multiple methods of verification, such as combining a keypad PIN with mobile access credentials, keycards and biometric identification. Research suggests that the use of MFA can prevent up to 90% of common cyber attacks that cause property access passwords to be compromised.
• Access security features: A keypad access system that provides unique PIN codes, up to 16 digits long, for each user can further enhance security and prevent unauthorized individuals from gaining access.
• Integration capabilities: To simplify daily management processes and reduce time and labor costs, property owners should look for keypad access systems equipped with open API and systems that support third-party hardware and software integrations. This helps ensure that all existing and future devices can be seamlessly connected.
• Cloud management: By operating a keypad access control system in a cloud-based platform, admins can update directories, manage permissions and view system usage through remote management. Cloud access control operators can also receive automatic updates and create integrated dashboards, combining keypad access controls with wider security features.

Conclusion

Keypad access control systems are often viewed by property owners and security teams as one of the most convenient and cost-effective access management solutions on the market. Keypad readers are generally compact, easy to install, simple to operate and able to be integrated with wider security features.

While the benefits of installing keypad access systems are numerous, property owners should be aware of some potential flaws before settling on a particular device. Consider implementing MFA for any commercial keypad lock systems, and look for devices capable of issuing longer PIN codes, as well as access control hardware units equipped with real-time alerts and cloud-based functionality.

To choose the best keypad access control system for a building, property owners should consult commercial PIN code door lock and access control providers to develop an integrated network capable of operating with existing technologies. Integrating different parts into one holistic system allows operators a comprehensive view of security, enabling a faster response to potential issues and enhancing overall safety.
