- Keypad not paired to the lock
- Code not created/synced in the app
- Keypad out of Bluetooth range of the lock
Problem Description
You are setting up the August Keypad to control your August smart lock with PIN codes. The keypad mounts outside your door (attached with adhesive or screws) and communicates with the lock via Bluetooth. This guide covers installing the keypad, pairing it with your lock, and programming access codes in the August app.
Why This Happens in Real Homes
The August Smart Keypad lets you unlock with a PIN instead of your phone, but it only works once it's paired to the lock and codes are created in the app — the keypad relays the code to the lock over Bluetooth, so range and pairing matter. A code that "doesn't work" is often unsynced or the keypad out of range.
Pair the keypad to the lock in the August app, create your entry codes there, and mount the keypad close enough for a solid Bluetooth link so codes reach the lock. Add codes with the lock online so they sync, use valid codes within any schedule, and keep both units' batteries fresh. If a code is accepted but the door doesn't open, the issue is deadbolt alignment, not the keypad.
Symptoms
- Setting up keypad entry codes
- Keypad not unlocking with a code
- Code rejected
- Keypad won't pair to the lock
- New code not working
- Keypad unresponsive
- Backlight but no unlock
- Codes not syncing
Recognize these? Here's what usually causes it.
Common Causes
- Keypad not paired to the lock
- Code not created/synced in the app
- Keypad out of Bluetooth range of the lock
- Low keypad or lock batteries
- Wrong code or expired schedule
- Lock offline when the code was added
- Firmware out of date
- Deadbolt binding (code accepted, won't open)
Most fixes happen in the first 3 steps.
Always keep a physical backup key accessible outside your home in case of total lock failure. Never perform a factory reset while locked out as this may disable all electronic access. Ensure battery level is above 50 percent before firmware updates to prevent corruption.

Step-by-Step Solution
Install the keypad
The August Smart Keypad mounts outside your door using the included adhesive strip or screws. Position it within 5-10 feet of the lock — the keypad communicates with the lock via Bluetooth, so it needs to be close enough for a reliable connection. Mount it at a comfortable height for entering codes (about 4 feet). Insert two CR123A batteries and the keypad powers on automatically with a backlit display.

$6.96Pair the keypad with your lock
Open the August app, go to your lock settings, and select Keypad. Tap Set Up Keypad and follow the prompts. The app searches for the keypad via Bluetooth — keep your phone near both the lock and the keypad. Once found, the app pairs them. The keypad is now linked to your specific lock. If the app cannot find the keypad, pull one battery out, wait 10 seconds, reinsert it, and try again.
Create access codes
In the August app under Keypad settings, tap Add Access Code. Create a 4-8 digit code and assign it to a person. You can create multiple codes — one for each household member, one for a dog walker, one for a cleaner. Each code can have a schedule (always active, weekdays only, specific hours) or be a one-time code that expires after a single use. Avoid simple codes like 1234 or 0000.
Use the keypad
Walk up to the keypad — the proximity sensor wakes it and the backlight turns on. Enter your code on the touchscreen and press the August logo button (or the checkmark, depending on model) to confirm. The lock should respond within 2-3 seconds. If the code is correct, the lock unlocks. To lock, press the August logo button without entering a code. The keypad beeps to confirm each action.
Fix keypad not unlocking
If you enter the correct code but the lock does not respond, check the Bluetooth connection between the keypad and lock. Move the keypad closer if it is at the edge of range. Make sure the access code is active and not outside its scheduled hours. If the keypad display lights up but no codes work, the keypad may have lost its pairing — remove it in the August app and re-pair. If the keypad does not light up at all, replace the CR123A batteries.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the keypad rejects valid codes, a lockout timer may be running — five failed entries locks most keypads silently for 5–10 minutes.
Set up auto-lock to engage 30 seconds after the door closes so you never accidentally leave it unlocked. Create temporary access codes for guests and service workers that automatically expire after a set time period.
Most smart lock failures people label as hardware issues turn out to be a code wiped during a sync, or a setting reset nobody remembers triggering.
