AES EKPD-K, Wireless eKeypad includes eTrans50 Transceiver
The AES EKPD-K is a wireless eKeypad kit that includes the AES coin-battery-operated eKeypad and an eTrans50 transceiver. It is designed for select AES e-Loop, e-Trans, gate, door, and access control applications where a wireless keypad and compatible receiving transceiver are required together.
This kit is useful when a keypad needs to be added without running keypad wiring back to the gate operator or access control point. In the correct setup, the user enters an authorized PIN at the wireless eKeypad, the keypad transmits the command to the included eTrans50 transceiver, and the eTrans50 relay output is wired to the approved gate operator, door controller, or access control input.
The EKPD-K should be ordered by exact AES part number, required kit contents, receiver/transceiver type, code capacity, channel needs, and relay wiring requirements. Do not choose this kit only because a wireless keypad is needed, since EKPD, EKPD-K, EKPD-KT, and EKPD-KLT may include different receiving equipment.
What This Wireless eKeypad Kit Does
The EKPD-K provides a wireless PIN-code keypad and an eTrans50 transceiver for compatible AES wireless access control layouts. The keypad is battery operated and transmits wirelessly, while the eTrans50 receives the keypad signal and provides a relay output for the controlled device.
This kit does not operate a gate, door, lock, or access point by itself without proper installation. Final operation depends on the eTrans50 power source, keypad programming, relay assignment, gate operator input, access control wiring, receiver setup, antenna placement, and required safety devices.
Compatible With
Use the AES EKPD-K only where the AES documentation, site design, product label, or supplier cross-reference confirms compatibility. Compatibility depends on the keypad, included eTrans50 transceiver, 433.39 MHz wireless platform, relay output requirements, programming method, and controlled equipment.
- Select AES wireless eKeypad applications where EKPD-K is listed as the kit with eTrans50 transceiver
- Select AES e-Loop and e-Trans access control layouts requiring a wireless keypad and eTrans50 receiver/transceiver
- Gate operator input applications where the eTrans50 relay output is wired to an approved open, radio, push-button, free-exit, or access control input
- Door, pedestrian gate, lock, or access control applications where the receiving relay and wiring are approved for the controlled equipment
- Applications requiring up to 200 user codes, 1 supervisor code, and 3 keypad channels where supported by the installed system
- Single-relay applications where the eTrans50 relay output is suitable for the desired gate, door, or auxiliary function
- Sites where wireless keypad installation is preferred over trenching or running new keypad wiring
- Repairs or replacements where the original kit is marked, listed, or cross-referenced as EKPD-K
Important Compatibility Warning
The AES EKPD-K is the wireless eKeypad kit with eTrans50 transceiver. It should not be confused with the EKPD keypad-only version. If the site already has a compatible receiver/transceiver, the keypad-only version may be the correct item instead. If the site needs the eTrans50 receiver/transceiver included, EKPD-K is the more appropriate kit style.
Do not assume all AES wireless eKeypad kits include the same receiver. EKPD-K is commonly associated with eTrans50, EKPD-KT is commonly associated with eTrans100, and EKPD-KLT is commonly associated with eTrans200. Package contents should be verified before ordering or publishing final kit claims.
The eTrans50 relay output must be wired only to an approved low-voltage control input. Do not use the relay to switch high-voltage circuits directly or bypass gate operator safety inputs, access permissions, fire access wiring, monitored entrapment devices, photo eyes, or safety edges.

Technician Note
If the AES EKPD-K will not activate the gate or access point, troubleshoot both the keypad and the eTrans50 side of the system. Check the CR2450 keypad battery, keypad lock/unlock status, PIN programming, channel assignment, eTrans50 power, receiver coding, relay output, antenna placement, range, and gate operator input wiring.
If the keypad accepts a code but the gate does not move, the keypad may not be the problem. Check the eTrans50 relay output, relay wiring to the operator, access control input, operator status, fire access interface, and safety circuit before replacing parts.
If the range is inconsistent, look closely at the eTrans50 mounting location and antenna path. Metal enclosures, block walls, long distances, electrical noise, and poor antenna placement can make a properly coded keypad appear unreliable.
Before Ordering, Confirm
- The required kit part number is EKPD-K.
- The installation needs the wireless eKeypad with eTrans50 transceiver, not the keypad-only EKPD version.
- The package includes the wireless eKeypad, eTrans50 transceiver, and any listed mounting screws or accessories.
- The system requires the eTrans50 style receiver/transceiver rather than eTrans100 or eTrans200.
- The controlled equipment has an approved low-voltage input for the eTrans50 relay output.
- The eTrans50 relay count, relay rating, and channel assignment are suitable for the gate, door, or access control input.
- The keypad code capacity, 3-channel operation, and supervisor code functions meet the job requirements.
- The keypad battery type is CR2450 and the package contents are confirmed.
- The wireless range and mounting location are suitable for reliable communication.
- The issue is not caused by a dead keypad battery, missing programming, low receiver power, antenna issue, relay wiring problem, or gate operator input fault.
Installation and Service Notes
- Install and program the EKPD-K only on systems you are authorized to service.
- Follow AES instructions for coding the wireless eKeypad into the included eTrans50 transceiver.
- Confirm keypad channel assignment before wiring relay outputs to gate, door, lock, or auxiliary functions.
- Use the correct CR2450 keypad battery and observe battery polarity.
- Power the eTrans50 only within the voltage range and wiring method shown on the current label or manual.
- Do not connect eTrans50 relay outputs directly to high-voltage loads or unsupported operator terminals.
- Mount the keypad securely and avoid locations where water can sit behind the housing or vehicles can strike the keypad.
- Mount the eTrans50 where the radio path is as clear as practical and where wiring is protected.
- After setup, test each user code, supervisor code function, assigned channel, eTrans50 relay output, and controlled device response.
- Do not bypass monitored gate safety inputs, photo eyes, safety edges, emergency access equipment, access permissions, fire access wiring, or required entrapment protection during testing.
Professional Advisory
A qualified gate, access control, or low-voltage technician should install or service the AES EKPD-K when the system controls a gate operator, automatic door, magnetic lock, electric strike, intercom, telephone entry system, fire access system, or monitored safety circuit. Wireless keypad access should be programmed and tested carefully, and it should never be used to bypass required safety devices, access permissions, emergency access requirements, or gate operator protections.
Product Questions & Answers

No. EKPD is the wireless eKeypad only. EKPD-K is the kit version that includes the eTrans50 transceiver where supplied as listed.
Is AES EKPD-K the same as EKPD-KT?
No. EKPD-K is associated with the eTrans50 transceiver, while EKPD-KT is commonly associated with an eTrans100 transceiver. Package contents should be verified before substituting.
How many user codes does the AES EKPD-K support?
The wireless eKeypad included with EKPD-K supports up to 200 user codes and 1 supervisor code where programmed according to AES instructions and used with compatible equipment.
What battery does the EKPD-K keypad use?
The wireless eKeypad is commonly specified with a CR2450 lithium coin cell battery and 3V DC operation. Confirm the battery type, inclusion, and polarity before service.
What does the eTrans50 do in the EKPD-K kit?
The eTrans50 receives the wireless keypad signal and provides one relay output for an approved gate, door, or access control input. Relay wiring and channel assignment must match the controlled equipment.
What should I check before ordering AES EKPD-K?
Confirm the exact EKPD-K part number, included eTrans50 transceiver, keypad battery type, code capacity, channel requirements, relay wiring, power requirements, package contents, and whether the job needs this kit instead of keypad-only EKPD.
