Sentry 300 050520 Wireless Keypad Overview
The Sentry 300 050520 wireless keypad provides code-based gate access for compatible USAutomatic and Sentry wireless receiver systems. Instead of carrying a remote, an authorized user enters an access code at the keypad, and the keypad transmits a wireless command to the compatible receiver. It is commonly used on residential driveways, ranch gates, estate entrances, and similar Sentry 300 swing gate installations.
This keypad uses the USAutomatic/Sentry wireless platform and should be matched to the receiver technology. It is commonly associated with 433.92 MHz operation and fixed-code style compatibility. If the operator has been updated with a different receiver, or if the customer needs a hardwired keypad, this may not be the correct part.

Technician Note
Before replacing a keypad, try a fresh battery, inspect for water damage or worn keys, and confirm the receiver still responds to a handheld transmitter. A receiver or antenna issue can look like a failed keypad.
Before Ordering Checklist
- Confirm the gate system has a compatible USAutomatic/Sentry wireless receiver.
- Verify whether the existing keypad is 050520 plastic wireless keypad or another model such as a metal keypad.
- Check code capacity, desired access codes, and mounting location.
- Replace the battery and test a known working transmitter before diagnosing keypad failure.
- Do not use a wireless keypad where a hardwired access-control keypad is required.
Professional Advisory
Keypad programming should be tested with the gate area clear. For shared properties, update access codes when tenants, vendors, or staff change.
