Changing a keypad lock code takes about two minutes on almost any electronic deadbolt: find the programming code on the sticker inside the lock, enter programming mode, delete the old user code, then enter the new one twice to confirm.
Most people don’t think about their keypad code until they need to change it fast. A roommate moved out. A contractor still has the number. Someone shared it with a dog walker two years ago and forgot all about it. The good news is that changing the code is one of the simplest things you can do on a keypad deadbolt, and you don’t need a locksmith for it in most cases. Here’s how it works across the three brands that show up most in San Diego County homes: Schlage, Kwikset, and Yale.
How do you change the code on a keypad deadbolt?
Nearly every electronic keypad lock uses the same basic four-step method, even though the exact button sequence differs by brand and model.
- Find your programming code. This is usually a 6-digit master code printed on a sticker inside the lock’s battery compartment or listed in the manual that came with it. It’s different from the everyday user code you type to unlock the door.
- Put the lock into programming mode. This is typically done by entering the programming code followed by a specific function button (often labeled “Program,” “Schlage,” or a lock icon depending on the brand).
- Delete the old user code. Programming mode gives you an option to remove an existing code before adding a new one, so old codes don’t linger unused.
- Enter the new code twice. Most locks require you to enter a 4 to 8 digit code twice in a row to confirm it was typed correctly, then the lock beeps or flashes to confirm the save.
If you’ve lost the programming code sticker, check the manual (most manufacturers post PDFs of every model online) or look at the printed code on the back plate of the lock, which is visible once the interior cover is removed. If none of that works, a factory reset is the fallback, and we’ll cover that below.
How to change a Schlage keypad lock code
Schlage splits into two families, and knowing which one you have determines the steps.
The mechanical BE365 uses a 6-digit programming code printed directly on the back of the lock, visible from inside the door once you remove the interior cover. You enter that code on the keypad, which puts the lock into programming mode, then follow the on-lock prompts to add or delete a user code.
The electronic Camelot, Encode, FE595, and BE469 keypads work differently. You enter the programming code, press the Schlage button (sometimes labeled with the Schlage logo), then choose the add or delete function to manage user codes. The programming code lives on a sticker inside the lock housing or in the printed manual that shipped with it. If you can’t find either, Schlage support can walk you through a reset based on your exact model number, which is printed on the interior mounting plate.
If your Encode keypad is glitching, delaying, or not accepting codes at all, that’s usually a connectivity or firmware issue rather than a code problem. Our guide on Schlage Encode problems and fixes covers the most common causes.
How to change a Kwikset SmartCode code
Kwikset’s SmartCode line, including the 909, 914, 916, and Halo models, follows a program-button pattern.
With the door open, press the Program button on the interior side of the lock, enter your new code on the keypad, then press the Kwikset button (or the lock icon, depending on model) to save it. Deleting a code follows a similar path, usually by holding the Program button down longer to enter a delete mode before selecting the code slot to remove.
Kwikset locks ship with a default programming code, and if that’s never been changed, anyone with the manual could technically access it. It’s worth checking that your programming code was updated from the factory default when the lock was first installed. If you’re not sure it ever was, that’s a good reason to have it reset properly, either yourself following the manual step by step or through a quick visit from a San Diego locksmith.
How to change a Yale Assure keypad code
The Yale Assure touchscreen uses your master PIN as the gatekeeper for any code change.
Enter the master code followed by the # key to open the menu, then use the on-screen or keypad prompts to add or delete a user code slot. The master PIN is set during initial setup, and if you never changed it from the default, that’s the first thing worth updating. Yale’s manual walks through the exact menu navigation for your specific model, since the touchscreen interface has changed slightly across generations.
If the touchscreen is unresponsive, lagging, or not registering the master code at all, that’s more often a battery or calibration issue than a lockout. Our post on Yale Assure lock problems and fixes covers the most common failure points before you assume the worst.
What if the keypad code won’t change or the lock won’t respond?
Weak or dying batteries are the single most common reason a keypad won’t accept a new code, even before mechanical failure.
Most keypad deadbolts warn you with a flashing red light or a low-battery chime well before they fail outright, but plenty of people ignore it until the lock stops responding to any input, including code changes. Swap the batteries first, always, before assuming anything else is wrong.
If fresh batteries don’t fix it, a factory reset clears every stored code and returns the lock to its default programming code, which lets you start over from a clean slate. Every brand has a slightly different reset sequence, usually involving holding a button combination for 10 to 30 seconds, and it’s detailed in the manual for your exact model.
If the programming code is lost entirely, or the lock is glitching in a way a reset doesn’t fix, that usually means a hardware issue rather than a settings problem. At that point it’s worth having it looked at rather than fighting with it for another hour. For a broader troubleshooting rundown across brands, see our smart lock troubleshooting guide. If the battery died mid-lockout and you’re stuck outside right now, we’ve also covered what to do when a smart lock battery dies and you’re locked out.
When should you change your keypad code?
Change your keypad code any time someone who had it no longer should, and on a routine schedule even if nothing specific happened.
The most common triggers: a roommate or tenant moves out, you move into a place that already has a keypad deadbolt installed, you shared the code with a contractor, cleaner, or dog walker for a one-time job, or you simply haven’t changed it in over a year and can’t remember everyone who’s had it. None of these require replacing the lock itself, just updating the code, which takes minutes once you have the programming code in hand.
If you just moved into a home with an existing keypad lock and don’t trust that the previous programming code was ever changed, that’s a case where a full rekey of your locks (including the mechanical cylinder behind the keypad, if your model has one) is worth doing alongside the code change. Swift Key can connect San Diego County homeowners with locksmiths who handle both the electronic reprogramming and the physical rekey in the same visit, available 24/7 and same-day across the county.

Frequently asked questions
Can I change my keypad lock code myself without calling a locksmith?
Yes, changing a keypad code is designed to be a homeowner task and doesn’t require any tools beyond the code itself and the lock’s keypad.
What do I do if I never got the programming code for my keypad lock?
Check the sticker inside the battery compartment or the back plate of the lock first, then check the manufacturer’s website using your model number, since most brands post manuals as free downloads.
How often should I change my keypad lock code?
There’s no fixed rule, but changing it after any roommate, tenant, contractor, or service provider no longer needs access, or roughly once a year as routine upkeep, keeps the list of people who know it short.
Will a factory reset on my keypad lock delete all my codes?
Yes, a factory reset clears every stored user code and returns the lock to its original default programming code, so you’ll need to reprogram user codes from scratch afterward.
Is a keypad deadbolt less secure than a regular deadbolt if I keep changing the code?
No, changing the code doesn’t weaken the lock’s physical security at all. It’s the same bolt and cylinder either way, and rotating who has access is one of the better security habits a homeowner can keep up with.
