Hyundai Santa Fe: Remote key / Remote key precautions

Hyundai Santa Fe (TM) 2019-2024 Owner's Manual / Convenience features / Accessing your vehicle / Remote key / Remote key precautions

The remote key will not work if any of the following occur:

The key is in the ignition switch.
You exceed the operating distance limit (about 10 m [30 feet]).
The remote key battery is weak.
Other vehicles or objects may be blocking the signal.
The weather is extremely cold.
The remote key is close to a radio transmitter such as a radio station or an airport which can interfere with normal operation of the remote key.

When the remote key does not work correctly, open and close the door with the mechanical key. If you have a problem with the remote key, it is recommended that you contact an authorized HYUNDAI dealer.

If the remote key is in close proximity to your mobile phone, the signal could be blocked by your mobile phone’s normal operational signals.

This is especially important when the phone is active such as making and receiving calls, text messaging, and/ or sending/receiving emails.

Avoid placing the remote key and your mobile phone in the same location and always try to maintain an adequate distance between the two devices.
