She Has Learned the Code: Spotting the Keypad Before the Door Opens

A keypad lock is meant to keep the door closed to anyone who does not know the number. For a person with dementia, the number is not always the barrier it appears to be. She may watch your fingers across the keys for months without any sign that she is paying attention, and then one afternoon she presses the sequence herself. The early signs are small, and they show up at the keypad before they show up at the door.

What to watch for

She stands at the keypad for a long time, or returns to it after you have walked away. She presses digits in a rhythm while you are in another room. She says the numbers aloud, or asks what the code is. The keys near the code wear shiny sooner than the rest. Any one of these can be coincidence. Two or three in the same week means the code has stopped being private.

How the code gets learned

Codes tend to get learned in ordinary ways. The same number has been used for years and never changed. A helper or neighbor types it in front of her. A guest mentions it without thinking. The code is written on a card taped near the frame, or on a sticky note in the drawer by the door. The lock works well for the house and poorly for the person it was meant to protect.

What to check this week

Walk to the door once as if you had never seen the code. Look for writing near the frame, worn keys, and any spot where someone in the hall can see your hands. Then change the code to something with no family dates, phone numbers, or addresses in it, and keep the new number off paper in the house. Tell each helper and visitor the new number in person, not by text where she might see the screen.

Check the way out from inside

Before you change anything, confirm that the door opens from the inside without a code. A lock that traps everyone in the house is a different hazard, and a keypad should never be the only way out. If you are unsure what the rule is for your home, ask your local fire department or building inspector. Then test the inside release yourself, with the door closed, so you know exactly how it feels to open it.
