How to Buy a Smart Electronic Deadbolt

Get a keyless keypad lock on sale and spread the cost out without paying interest.

VoAtlas editorial Updated · 3 min read
Typical cost $220 before anything else
Across the 0% window $12.22/mo 18 months, no interest

How we got that: $220 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.

A solid smart deadbolt keeps your keys where they belong—out of the picture—while letting family and dog walkers in with a quick tap. You want one built with solid metal housing and reliable auto-lock so you only buy the thing once instead of replacing a jammed motor in two years.

Keep an eye on the release cycle right now. Brands drop new security hardware every fall, which means holiday doorbuster events are the exact right time to grab last year's model at a steep discount without losing out on core features.

That 18-month window is a hard deadline, not free money. If you still have a balance left when the clock runs out, interest charges will kick in on the original purchase amount.

The steps

  1. 01

    Pick your doorbuster window

    Smart locks hit their lowest prices during major holiday sales events in November and December. Track the model you want now so you recognize a real price drop when it hits.

  2. 02

    Check your door fit

    Measure your backset and bore hole before you buy anything. Most standard US doors work fine, but thick doors or older mortise setups need special mounting kits.

  3. 03

    Map out the math

    A typical $220 smart lock comes down to manageable chunks if you spread out the payments. You can use the Citi Simplicity® Credit Card, which gives you 0% for 18 months on purchases and balance transfers from date of account opening.

  4. 04

    Test the manual backup

    Never buy a deadbolt that lacks a physical key override or a hidden 9V terminal for dead batteries. Technology fails, and you do not want to get locked out in the rain.

  5. 05

    Install and test codes

    Put fresh lithium batteries in right out of the box and program your permanent codes before you throw away the box. Test the auto-lock feature three times before you trust it.

  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

Do smart locks drain batteries fast?

Most decent keyless locks run for six to twelve months on four AA batteries. Cold weather drains them faster, so stick to lithium batteries if you live somewhere with freezing winters.

What happens if the power goes out?

Smart deadbolts run on internal batteries, so your home power grid going down will not affect the keypad or auto-lock. You are only in trouble if the batteries die completely and you forgot the physical backup key.

Can hackers open my deadbolt?

Most smart locks use encrypted Bluetooth or Z-Wave signals that are tough to intercept. Physical break-ins through a kicked-in door frame are way more common than high-tech remote hacking.

Will it fit my existing deadbolt hole?

Almost all standard US residential deadbolts use a universal 2-twist bore hole. You can usually swap out a dumb lock for a smart one in about fifteen minutes with just a screwdriver.
