The lockbox is still within the range of the receiver when it is mounted to the rear window. This will cause the key fob to continuously transmit a RF (radio frequency) to the receiver. It is recommended to use a lockbox with RFID shielding to block the RF signal and prevent battery drain.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10196583-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10196583-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10196583","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"HYUNDAI","model":"ELANTRA","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_hyundai_elantra"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
