Metal Keypads and Encrypted Keypads for Access Control
Access control keyboards grant or deny entry to spaces, buildings and secure areas, and they are normally mounted at the door or barrier itself where anyone can reach them.
Access control keyboards grant or deny entry to spaces, buildings and secure areas, and they are normally mounted at the door or barrier itself where anyone can reach them. KEYU manufactures the metal keypads, side keypads and backlit keyboards that sit at that point of contact, for door controllers, gate systems and integrated security panels. Because PIN codes can be changed or revoked at any moment, the hardware around them has to stay serviceable for far longer than any single credential.
What Goes Wrong On Site
- An entry device mounted in a public corridor or on an outside wall is handled constantly and is the first thing attacked when someone is refused entry
- Printed or moulded digits rub away under heavy daily traffic, leaving a pad that still works but can no longer be read
- PIN entry at an exposed door needs protection at the keypad itself, since the code travels from the keys to the controller
- Integrators have to make one keypad work across several door controller types, and a device with a fixed interface limits which projects it can be used on
- Mixed credentials on one door, such as a PIN together with a card or biometric reader, leave very little panel space for the keys
What Buyers In This Sector Need
- A metal front plate and key construction that survives forced handling as well as ordinary use
- Legends that stay legible over years of traffic rather than wearing off the key surface
- Encrypted PIN entry for doors where the code is the primary credential
- Backlighting so codes can be entered in unlit corridors, stairwells and outdoor entrances
Typical Installations
- Door-mounted PIN keypads in office buildings and residential blocks, integrated with an existing controller
- Gate and barrier entry points at industrial sites, where the pad is outdoors and unsupervised
- Secure areas inside hospitals, schools and data rooms where access is restricted by time of day or by zone
- Multi-factor readers where a PIN keypad is combined with a card, fob or biometric stage on the same panel
- Side keypads for narrow door frames and mullion mounting where a square keypad will not fit
- Turnstile and lift-access panels that log every attempt and need an input device matching the rest of the security hardware
How A Project Runs
Step
Tell us the controller you are integrating with, the key layout and whether the code path needs to be encrypted
Step
We select a base platform from our existing molds or start a new front plate if the opening demands it
Step
Drawings and a 3D model are issued so your mechanical and electrical teams can check fit and pinout together
Step
We produce a sample for bench testing against your controller before committing to tooling
Step
Production follows sample approval, with sheet-metal processing handled under our ISO 9001:2015 quality management system
Step
We keep the drawing and tooling records so a later project on the same door hardware reorders without redesign

Access Control Questions
Can your keypads integrate with our existing door controller?
Send us the controller interface and pinout and we build the keypad to match it. Matrix output and common serial or USB interfaces are all things we handle at the design stage rather than asking you to adapt.
What makes a metal keypad better than a plastic one at a door?
A door keypad is touched by everyone who passes and hit by anyone refused entry. A stainless steel plate and metal keys take that treatment, and the legends are produced into the surface rather than printed on top, so they stay readable.
Do you make keypads that fit a narrow door mullion?
Yes. Our side keypad format is designed for narrow columns and frames where a standard square pad cannot be mounted. We can also design a new plate outline to your frame dimensions.
Is the PIN protected between the keypad and the controller?
For applications that require it we supply encrypting pin pads, where the entered code is encrypted at the device rather than passed on as plain key data. Tell us the security requirement your project works to and we will match the right product type.
Can we order a small quantity for a pilot installation first?
We normally build a sample from your approved drawing before any production run, precisely so you can install and prove it on site. Discuss the pilot quantity with our sales team and we will confirm what is workable for your build.
Specifying Input Devices For Access Control
Send the panel cutout, the interface your controller expects and the environment the terminal sits in.
