Changing your smart lock’s PIN is one of those simple maintenance tasks everyone should know — whether you are refreshing security, removing an old guest code, or updating access after someone moves out. Knowing how to change password on smart door lock units takes only a minute once you know where to look. This guide walks you through both the keypad and app methods, plus tips for a strong, safe code, so your smart door lock stays secure.
Why and when to change your password
It is good practice to change your smart lock’s password periodically, and essential at certain moments: after sharing a temporary code with a guest or worker, when a tenant or helper leaves, if you suspect anyone has seen your PIN, or simply as routine security hygiene every few months. Knowing how to change password on smart door lock units means you can keep access tight and current without ever calling a locksmith. The process is quick and can be done as often as you like, so there is no reason to keep using a code that has been shared too widely or grown stale.
How to change password on smart door lock: the methods
There are two main ways to change a code, summarised in the table below, with detailed steps following.
| Method | Steps in brief |
|---|---|
| Keypad admin menu | Enter admin PIN, open settings, set new PIN |
| App | Open the lock, edit user, update the code |
| Add guest code | Create a new temporary PIN in the app |
| Delete a code | Remove any old or shared PIN |
| If you forget admin PIN | Reset per manual; re-enrol users |
Method 1: Using the keypad admin menu
Most smart locks let you change the password directly at the door. To do this, you enter the lock’s administrator (master) menu, usually by pressing a function or asterisk key and entering your admin PIN. From the settings menu you select the option to manage or change user codes, choose the code you want to update, and enter a new PIN, confirming it when prompted. The exact key sequence varies by model, so keep your lock’s manual handy the first time. Once confirmed, the old code stops working immediately and the new one takes effect. This keypad method is handy when you are at the door and want a quick change.
Method 2: Using the app
The easier and more flexible way to change a password is through the app. On a Covlor® lock, open the Tuya / Smart Life app, select your lock, and go to the user or password management section. There you can edit an existing user’s code, delete an old PIN, or create a new one, all from your phone — even remotely. The app method is ideal because it gives you a clear overview of every code and user, lets you manage access without being at the door, and makes it simple to add time-limited guest codes. For most people, the app is the most convenient way to keep codes current.
Adding and deleting guest codes
Part of good password management is handling temporary codes properly. When you give a guest, cleaner or delivery partner access, create a separate guest PIN rather than sharing your own, and delete it once it is no longer needed. In the app you can create a time-limited code that expires automatically, which is even better. Knowing how to change password on smart door lock units includes this routine of adding and removing guest codes, so access always reflects who currently needs it. Keeping guest codes separate from your main PIN means you can revoke them freely without ever having to change your own everyday code.
Choosing a strong, safe PIN
When setting a new password, choose it wisely. Avoid obvious codes like 1234, 0000, or your birth year, and do not reuse a PIN that others may have seen. Pick a number that is easy for you to remember but hard for others to guess, and use the lock’s anti-peep feature — which lets you pad your real PIN with random digits — when entering it in view of others. If your lock supports multiple user codes, give each family member their own, so you can manage access individually. A thoughtfully chosen PIN is a simple but important part of keeping your smart lock genuinely secure.
If you forget the admin password
Occasionally someone forgets the administrator PIN, which is needed to manage other codes. If this happens, do not worry — most smart locks have a documented reset procedure in their manual, typically involving a reset button inside the lock and re-initialising it, after which you set a new admin code and re-enrol users and fingerprints. Because this clears existing settings, keep a record of your admin PIN somewhere safe. For Covlor® locks, the app and manual guide you through recovery. Knowing this fallback exists means a forgotten admin code is a minor, recoverable hiccup rather than a serious problem.
Keeping your lock secure over time
Changing passwords is part of a broader habit of keeping your smart lock secure. Review your list of codes periodically and remove any you no longer recognise or need. Protect your app account with a strong, unique password and two-factor authentication where available. Keep the lock’s firmware and app updated. And teach family members good habits, like using anti-peep padding and not sharing the main PIN casually. Knowing how to change password on smart door lock units is the practical core of this routine, letting you keep access current and tight with just a minute of effort whenever something changes.
Choosing a lock with easy management
If you are still choosing a lock, look for one with straightforward password management — a clear keypad admin menu and, importantly, a good app that makes adding, changing and deleting codes simple. Covlor® locks offer both, with the Tuya / Smart Life app giving you full, remote control over users and codes, including time-limited guest access. Easy management means you will actually keep your codes current rather than leaving a shared PIN in place for years. Combined with reliable build quality and backup power, convenient code management is a feature well worth prioritising in any smart door lock.
Managing multiple users and codes
Most households have several people who need access, and knowing how to change password on smart door lock units extends naturally to managing multiple users. Give each family member their own PIN or enrolled fingerprint rather than sharing one code, so you can see who entered and update or remove any individual’s access without affecting the others. Keep a mental or written note of which code belongs to whom, and review the list occasionally to remove anyone who no longer needs access. The app makes this easy, showing all users in one place. Managing codes individually like this is more secure and more convenient than a single shared PIN, and it is a small habit that keeps your household’s access tidy and under control.
