The Enforcer PR-K1S1-A proximity card group is used for adding or replacing card credentials on compatible SECO-LARM and ENFORCER access control systems. This listing is written for the 50 cards group shown in the product name. The card technology is EM125 / 125 kHz proximity, which is common on many SECO-LARM keypad/card-reader and Wiegand reader installations used at pedestrian entries, gate access points, office doors, apartment entrances, storage facilities, and controlled commercial access points.
These cards do not operate a gate or door by themselves. A PR-K1S1-A card is presented to a compatible reader, and the reader or access controller decides whether to activate a door strike, maglock, gate operator input, barrier gate input, or other access relay. For that reason, the most important ordering detail is not the physical card shape alone; it is the credential technology accepted by the installed reader. If the existing system is built around SECO-LARM EM125 card readers, these cards are commonly used as additional credentials for new users, replacement cards, tenant turnover, employee changes, and property management inventory.
Correct fitment matters because access cards that look similar are not always interchangeable. HID Prox, MIFARE, iCLASS, DESFire, encrypted smart cards, Bluetooth credentials, and garage-door RF transmitters use different technologies. A 125 kHz EM card must also be enrolled properly through the reader or controller programming process. Before ordering, verify the reader model, the accepted card type, and whether the site administrator has permission to add new card numbers to the system.

Use this compatibility section as a reader-family guide, not as a substitute for checking the access control manual. PR-K1S1-A cards are intended for SECO-LARM proximity readers that use 125 kHz EM125 card technology.
The following numbers and terms are commonly associated with this card family. Some are exact card references, while others are related search variations or credential-family references.
When a customer says a card will not read, check the installed reader technology before blaming the card. A reader designed for another credential format may not react at all to an EM125 card. If the reader beeps or flashes but does not grant access, the card may be readable but not enrolled, assigned to the wrong user level, or blocked by schedule or controller programming.
For access-controlled gates, doors, and community entries, credential programming should be handled by the property manager, system administrator, or a qualified access control technician. Do not bypass locks, gate safety devices, entrapment protection, or access control relays to make a credential work. If the reader wiring, relay output, power supply, door hardware, or gate operator input is not functioning correctly, have the system inspected by a qualified technician.
This listing is written for the 50 card group shown in the uploaded product name. Because the manufacturer PR-K1S1-A is commonly referenced as a pack-of-10 card item, the group quantity should be verified against the store packaging before upload or fulfillment.
These cards are for SECO-LARM and ENFORCER proximity readers that accept 125 kHz EM125 cards. They must be enrolled into the reader, keypad, or access controller before use.
No. PR-K1S1-A cards are EM125 / 125 kHz proximity cards. They should not be ordered for HID Prox, MIFARE, iCLASS, DESFire, Bluetooth, or other access credential technologies unless the system documentation specifically says it accepts EM125 cards.
No. These are access credentials, not gate operator transmitters. They work only when presented to a compatible proximity reader that is connected to the gate, door, or access control system.
They are normally added to the access system during installation or user setup. Programming depends on the reader or keypad model, the controller setup, and the site administrator permissions.
