What Sets Off Walmart Door Alarms? [Must Read!] 

Walmart loses billions of dollars a year to theft in their stores, so they take security and tracking very seriously.

How Do Walmart’s Door Alarms Work?

Security sensors are placed on either side of Walmart’s public entrance and exit doors, searching for active and attached security tags.

The door alarms will sound a response signal when they detect a live tag frequency, alerting security of a possible shoplifting offense.

How Do Walmart Security Tags Work?

Walmart usually secures its goods with wired radio frequency tags, AutoPeg tags, or sticks on magnetic labels.

Security tags must be dismantled or deactivated by a store associate using specialist tools at the checkout. Live tags are designed to trigger door sensors when they are near.

If a customer were to attempt to remove the tag themselves would run the risk of setting off a separate alarm or cause the item permanent, irreversible damage.

Which Items Does Walmart Security Tag?

Walmart attaches security tags to high-value items such as electronics, batteries, clothing, furniture, jewelry, make-up, and desirable home accessories.

Thieves are most likely to target profitable items and therefore receive the most protection.

Walmart tends to leave lesser valued items such as candy bars, toilet paper, and unloaded gift cards as they will not incur a significant loss to Walmart should they be stolen.

What Happens If I Accidentally Set Off Walmart Alarms?

If you have innocently triggered Walmart’s door alarm, simply wait at the exit for a store associate to approach you.

On rare occasions, store associates may miss a tag, leaving it attached to purchased items. Make sure you have your receipt ready to prove the purchase of each item.

Security tags left on items from other stores may also set Walmart’s door alarm off upon entrance. You’ll need to head back to the previous store to have the tag deactivated or removed.

Do Barcodes Set Of Walmart Door Alarms?

No, barcodes will not set Walmart’s door alarms off. Barcodes are only compatible with store scans which indicate an individual item’s price and product information. RFID tags are often located near the barcode, which will set the alarm off.

Do Walmart Identify Thieves That Avoid Door Alarms?

Yes, alongside door sensors, Walmart equips stores with CCTV cameras that can detect shoplifters’ identity, even if they manage to avoid the alarm.

Additionally, Walmart undertakes stock checks which highlight unauthorized missing items.

Conclusion: What Sets Off Walmart Door Alarms?

Walmart’s door alarms are triggered by active security tags by sounding a response alarm at public entrances and exits.

Security tags are often attached to high-value items such as electronics, clothes, and selected make-up and must be deactivated by the cashier. Show your receipt to a store associate if you’ve accidentally sounded the alarm.
