Keypad locks fail in predictable ways, and a good share of the calls about them end with new batteries. Work through these before booking a visit.
Start with power
Batteries are the cause far more often than anything else, and cold accelerates it. A Colorado winter will take a set of alkalines from working to dead in the space of a cold snap.
- Replace all batteries at once with a fresh set from the same pack — never mix old and new.
- Use the battery type the manufacturer specifies.
- Check the contacts for corrosion or a loose battery tray.
- Some locks offer an emergency external power contact — check your manual.
Then check the door, not the lock
If the keypad beeps and the motor whirrs but the bolt does not move, the lock is working and the door is not. A door that has swelled or dropped puts the bolt out of line with the strike, and the motor cannot force it.
Test it with the door open. If the bolt throws cleanly in mid-air and jams when closed, it is an alignment problem, and the fix is the strike plate or the door, not the electronics.
Codes and connectivity
If a specific code has stopped working, it may have been an expiring or scheduled code. Try the master code. If the lock connects to an app, check whether it is online and whether a firmware update is stuck halfway.
A factory reset is a genuine option, but it wipes every code, so make sure you have a mechanical key or another way in first.
Winter-specific behaviour
Moisture that gets into the keypad and then freezes will make buttons unresponsive without anything actually being broken. So will a frozen latch. Both usually clear up when the temperature does — and if a lock does this every year, it is a sign the lock is not the right one for an exposed door.
When to call
New batteries, a tested alignment, and a master code that all fail together point at the lock body or wiring. At that point it is worth a call — and worth asking whether the lock is a model that tends to fail this way.
