Should I say 'I remember locking the door' or 'I remember to lock the door' when talking about my morning routine?

Asked byRavi AdminPosted Mar 22, 2026 8:16 PM3 answers27 upvotesCanonical URL

I'm a bit confused about the difference between saying "I remember locking the door" and "I remember to lock the door." This morning, I wasn't sure which one to use when talking to my friend about what I did before leaving home.

For example, if I want to talk about something I did before going to work, should I say, "I remember locking the door before leaving" or "I remember to lock the door before leaving"? They both sound correct to me, but I want to use the right one.

Could someone explain when to use each of these? Thanks!

What to KnowWhy It MattersExampleQuick Check
"I remember to lock the door each morning" = You don't forget to do it; you remember as part of your routine before leaving."I remember locking the door" = You did it already, and you remember the experience of doing it.This wording is correct because it matches the intended meaning in context.Can I explain why this form fits this sentence better than the alternative?
Writers often memorize a definition but miss the context cue that controls the correct choice.This helps you choose wording by meaning instead of surface form.A different phrasing is better when the literal meaning would be clearer.Did I choose this form for meaning, not because it looked familiar?

Explanation:

A practical pattern to remember is:

  • "remember + -ing" = you recall doing something (the action is finished).
  • "remember + to + verb" = you recall that you need to do something (your memory prompts the action).

Examples:

  • "I remember locking the door" = You did it already, and you remember the experience of doing it.
  • "I remember to lock the door each morning" = You don't forget to do it; you remember as part of your routine before leaving.

Self-check: Next time, ask yourself: "Am I talking about an action I did?" (use -ing) or "Am I talking about remembering to do something before I do it?" (use to + verb).

Practice: Try these: "I always remember (bring) my keys." "I don't remember (turn off) the oven."

Explanation:
Imagine you are at the door:

  • If you want to say, "I remembered that I needed to lock the door, and so I did it," you use 'I remembered to lock the door.'
  • If later, you think back and recall the moment when you turned the key, you use 'I remember locking the door.'

Examples:

  • "I remembered to pack my lunch" (you didn’t forget; you did it).
  • "I remember packing my lunch" (you recall the act itself).

Practice Tip:
Before you speak, ask: Am I remembering before (to do), or after (the action itself)? Try making examples about remembering to call a friend, and remembering calling a friend.

Explanation:
Many learners mix these forms, so let's correct sample mistakes:

  • Incorrect: "I remember to locking the door every morning."
    Correct: "I remember locking the door every morning." (Here, you're recalling the act itself.)

  • Incorrect: "I remember lock the door before work."
    Correct: "I remember to lock the door before work." (Here, you don't forget; it's your habit to remember and then do it.)

Guided Reminder:

  • Use -ing for memories of doing something.
  • Use to + verb for remembering to do it at the right moment.

Self-edit tip: After writing, check: Did the remembering cause the action (to)? Or am I recalling the action itself (-ing)? Try fixing another example: "I must remember (call/calling) my mom tonight."
