How to Fix ELK Keypad Time Not Updating Correctly
- Panel time set incorrectly
- No NTP sync (no M1XEP/network)
- Daylight-saving not handled
Problem Description
The Elk M1 keypad displays the wrong time — the clock is off by minutes, hours, or resets to a default time after power events. The M1 panel does not have network time sync, so the time must be set manually, maintained by the backup battery during outages, and adjusted for Daylight Saving Time transitions.
Why This Happens in Real Homes
The Elk M1 keypad displays the panel's clock, so a wrong time means the panel's time is off — either it was set incorrectly, it's drifting without an internet time sync, or daylight-saving isn't being handled. Keypads don't keep their own time; they mirror the panel.
Set the panel's time and date correctly (via a keypad or ElkRP), and if you have an M1XEP Ethernet module, enable NTP time synchronization so the panel keeps accurate time automatically from the internet. Configure daylight-saving handling and verify the timezone. Without NTP, the panel's clock drifts and needs periodic resetting, and a weak RTC backup can worsen it. With NTP via the M1XEP, the time stays correct on its own.
Symptoms
- Keypad shows the wrong time
- Time not updating
- Clock drifts
- Wrong time on the keypad
- Time off after DST
- Time won't set
- Clock incorrect
- Time resets wrong
Recognize these? Here's what usually causes it.
Common Causes
- Panel time set incorrectly
- No NTP sync (no M1XEP/network)
- Daylight-saving not handled
- Clock drift over time
- Timezone/DST settings
- Backup battery/RTC issue
- M1XEP not syncing time
- Programming time entry wrong
Most fixes happen in the first 3 steps.
Do not troubleshoot timed events until panel and keypad clocks are aligned.
Tools & Requirements
Step-by-Step Solution
Set the correct time in the M1 panel via ElkRP
The M1 panel is the time source for all keypads. If the panel time is wrong: all keypads display the wrong time. In ElkRP: connect to the M1 > System > Date/Time. Set the correct date, time, and timezone. Click 'Write to Panel.' All keypads update within seconds. The M1 does not have NTP (network time sync) — time is set manually and maintained by the panel's internal clock oscillator. It drifts a few minutes per month without correction.
Set the time directly from the keypad
If you do not have ElkRP access: set the time from the keypad. Enter the installer code (default 111111 unless changed) > access the programming menu > go to System > Date/Time. Enter the current date and time using the keypad numbers. Press the pound (#) key to confirm. The updated time syncs to all other keypads on the data bus. Check with your installer if you do not know the installer code.
Check the panel's backup battery
The M1 panel has a backup battery that maintains the clock during power outages. If the battery is dead or disconnected: the clock resets to a default time after every power loss. Check the battery: open the M1 panel enclosure. The backup battery is a 12V 4-7Ah sealed lead-acid battery. Measure its voltage: should be 12.5-13.8V when on charger. If below 12V: replace the battery. After replacing: set the correct time. The clock should now persist through power outages.
Check for power interruptions causing clock resets
If the time resets to the same wrong value periodically: the panel is losing power (main AC + battery both failing). Check the panel's AC power transformer: is it plugged in and providing 16.5VAC? Measure at the panel terminals. If voltage is low or absent: check the outlet, breaker, and transformer. If main AC is present but the battery is dead: the panel runs on AC but resets the clock during brief power blips (brownouts). A healthy battery bridges these blips.
Configure Daylight Saving Time settings
The M1 has DST settings that can cause the time to be wrong by exactly 1 hour twice a year. In ElkRP: System > Date/Time > DST settings. Verify DST is enabled if you are in a DST-observing timezone. Set the correct start and end dates for your region (US: second Sunday of March, first Sunday of November). If DST is disabled: you must manually adjust the time twice a year. If DST dates are wrong: the clock shifts an hour at the wrong time.
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.
Consistent clock settings are critical for schedule-dependent security logic.
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.

- No NTP sync (no M1XEP/network)
- Daylight-saving not handled
- Clock drift over time
- Timezone/DST settings
