RFID locker lock or keypad lock: which suits your site?

An RFID locker lock opens when an authorised card, wristband or key fob is held against the locker door, so users carry no metal key and staff can cancel or reassign access without changing hardware. A keypad locker lock does the same job with a PIN code. The right choice depends less on the number of lockers than on how they are used: fixed lockers assigned to one person, or shared lockers that change hands every day.

How does an RFID locker lock work?

The user presents a credential to a reader on, or behind, the locker door. The lock checks whether the credential is authorised for that locker and, if it is, a small motor releases the latch. When the user closes the door and presents the credential again, the lock re-engages.

General Kilit card locker locks such as the DK119 and the DK111 read MF and RF credentials at 13.56 MHz and 125 kHz. Because they read reliably through up to 40 mm of wood without an external antenna, they can be mounted out of sight inside wooden lockers, drawers and cabinets. Other points from the product data:

• a user capacity of 100 (DK111) or 10,000 (DK119), expandable on request;
• around 10,000 openings from the lithium battery, with a low-battery warning;
• on the DK119, a warning followed by automatic opening before the battery is completely flat;
• emergency opening with an external battery if the battery does run out;
• an audible signal when a card is read on the DK119, and operation from −25 °C to +70 °C at up to 95 % humidity;
• straightforward programming of the DK111 without a PC or software.

How do keypad locker locks differ?

Keypad locks such as the DK112 and DK116 use a PIN instead of a card. They can be set for permanent codes, for a locker assigned to one user, or temporary codes, where each new user of a shared locker sets a fresh code. After four wrong entries the keypad blocks for one minute, while an authorised manager can open the locker straight away with a master code. They run on four 1.5 V AAA alkaline batteries, give an audible low-battery warning and show a busy or free status by LED. General Kilit's product pages also list a stainless steel face, an optional power adapter connection and an alarm when the locker door is forced.

Three variants solve specific operating problems:

• DK112 OA: opens automatically after 12 or 24 hours, so day-use lockers are released overnight even if a user forgets to empty them.
• DK113: combines the keypad with MIFARE card use, and a master card can replace the master code.
• DK116: adds a latch handle and is offered as a rechargeable model.

Which lock suits gyms, spas, dormitories and staff rooms?

• Gyms with member cards or wristbands: an RFID locker lock lets members use one credential for the entrance and the locker, provided the card technology matches. Test the existing wristbands on a sample lock.
• Day-use spas and hammams: keypad locks in temporary-code mode avoid issuing and collecting credentials, and automatic-opening models free lockers at the end of the day.
• Student dormitories: lockers are usually assigned for a term, so either student cards or permanent PIN codes work well; see the student dormitory solutions.
• Staff changing rooms in hotels, hospitals and factories: fixed assignment with staff cards simplifies starters and leavers, because access is changed in the lock rather than by collecting keys.
• Offices and furniture makers: hidden card locks such as the DK111 suit drawers and cabinets where no visible keypad is wanted.

What happens if a code is forgotten or a battery runs out?

Plan this before installation, not after the first complaint. Keypad locks open with the master code, and card locks with a master card. Low-battery warnings leave time for scheduled replacement, and for card models that are already flat, an external battery supplies power for emergency opening. Lockers should be opened only by authorised staff, following a written procedure that records who opened which locker and why. Routine questions are covered on our support pages.

What should you check before ordering hundreds of locks?

In large projects, mechanical fit matters as much as the electronics. Before ordering 500 or 1,000 locks, confirm:

1. the credential technology, tested with the site's real cards or wristbands;
2. the locker material (timber, MDF, compact laminate or metal) and the door thickness;
3. the mounting position, cam or latch geometry and strike alignment;
4. the battery type, the expected openings per day and the replacement routine;
5. the master access and emergency opening procedure;
6. a sample installation on the actual locker before mass fitting;
7. spare parts and local technical support.

Locker manufacturers planning an OEM integration should involve the lock supplier at the design stage, so that mounting holes, lock position, cable routing and battery access are built into the locker rather than adapted afterwards.
