Remote key or Smart Key?
Hyundai’s official Indian i20 and i20 N Line manual, marked October 2023 onwards, describes both remote keys and Smart Keys. It also covers standard and optional equipment, so not every description applies to every vehicle.
This is an Indian-market example. For a vehicle in Israel, check its production year, starting system and appropriate manual. Mention whether the current key is original, a replacement or has a replacement shell.
Detection and battery messages
In that Indian manual, “Key not detected” describes failure to detect the Smart Key when the start button is pressed. “Low key battery” is a separate message relating to the key battery when switching off. The manual also includes “Press START button with key.”
Photograph your exact message and any indicator. These describe different conditions; none alone establishes that a new key is needed. Use the manual for your particular vehicle for backup operating instructions.
Changing response and comparison with a spare
The checked Indian i20 manual discusses interference from phones and electronic equipment near a remote or smart key. Mention whether the problem varies with location or nearby objects. This differs from a permanent fault following a drop.
If you have a spare, report whether it unlocks and starts under the same conditions. A working spare provides information but does not prove the cause is only the battery. If neither key produces a response, describe the dashboard too.
Key detection interference: useful comparisonsA battery number is not a dismantling guide
The Indian i20/i20 N Line manual from October 2023 onwards lists CR2032 for its described remote key types and Smart Key. However, opening illustrations and construction differ between types. A shared battery number does not make the opening procedure identical.
Check your key and its instructions before replacement. If the issue began afterwards, report the cell installed and what still works. Mention water exposure or a shell that came apart before buying another part.
Preparing a spare or replacing a lost key
With a working key, define the spare’s functions and request testing with the car. Without an available key, explain whether it was lost, stolen or locked inside. After loss, ask separately about the old key’s status.
