How to Budget for a Smart Front Door Lock and Handle Set

Upgrade your home security with a smart lock and handle set by catching seasonal sales and spreading the cost sensibly.

VoAtlas editorial Updated · 3 min read
Typical cost $500 before anything else
Across the 0% window $27.78/mo 18 months, no interest

How we got that: $500 spread evenly across the 18-month introductory window on the Citi Simplicity® Credit Card. Checked · at the bank Carry a balance past the window and the standard APR applies to what is left.

You stop carrying house keys and stop worrying about who has copies the day your new smart front door lock and handle set is installed. The deadbolt turns smoothly from your phone, and temporary entry codes make life easier for dog walkers and visiting family. Swapping out the hardware takes about an hour with a screwdriver and a drill if the latch holes need a slight adjustment.

We look for Prime Day sales in the summer or autumn discount events to grab the hardware at a lower price. You also want to check the alignment of your doorframe before buying so you don't run into jammed bolts.

That 0% window is a hard deadline, not free money, and any remaining balance left when it ends will trigger standard interest charges on what you owe.

The steps

  1. 01

    Check your door compatibility

    Measure your door thickness and backset distance before you buy anything. Most standard US doors work with smart locks, but older or custom doors might need extra drilling.

  2. 02

    Time the purchase for Prime Day

    Add the lock set to your cart early and watch the price drop during major retail sales events. Buying during these windows usually saves you about twenty to thirty percent off the retail price.

  3. 03

    Line up your installation tools

    Gather a fresh set of batteries, a screwdriver, and a smartphone before you start taking apart the old handle. Give yourself an uninterrupted hour to handle the wiring and calibration without rushing.

  4. 04

    Spread the cost with your card

    The Citi Simplicity® Credit Card gives you 0% for 18 months on purchases and balance transfers from date of account opening. Spreading a five hundred dollar lock set across that window comes out to about $27.78 per month.

  5. 05

    Set up your backup entry methods

    Program your primary code and test the physical backup key before you let go of your old set. Keep the physical key somewhere outside, like a lockbox or trusted neighbor's house, in case the batteries ever die completely.

  6. 06

    Check the card terms before you commit

    Every figure we publish for the Citi Simplicity® Credit Card carries the date a person verified it against Citi and a link to where they checked. Intro windows and APRs change without notice, so confirm the current terms before applying.

Common questions

What happens if the smart lock batteries die while I am away?

Most models have a hidden physical keyway or terminal ports underneath where you can touch a nine-volt battery to wake the keypad. This gives you just enough power to punch in your code and get inside.

Can I install a smart lock on an apartment door?

Usually only if your lease allows changing the exterior hardware. Many landlords require you to keep the existing keyed deadbolt, which means you might need to look for interior-only smart solutions instead.

Do smart locks work if my internet goes down?

Yes, because they rely on Bluetooth or local numeric codes stored directly on the device. You just won't be able to lock or unlock the door remotely from miles away until your Wi-Fi comes back.

Are smart locks hard to rekey?

Some models let you match the cylinder to your existing house key in a few seconds using a special tool. If yours doesn't, you'll just use the physical keys that come in the box as your backup.
