If the key fob on your Genesis GV70 (JK1, 2020–2024) has gone weak or the central locking has become intermittent, the coin cell inside is almost certainly flat. It’s a quick swap with a CR2032.
Battery First — What You Need
- A CR2032 coin cell.
- A small flat screwdriver (wrap the tip with tape to avoid marking the fob).
Replacing the Cell
- Slide out the mechanical key blade.
- Insert the taped screwdriver in the seam and remove the key cover.
- Remove the old cell.
- Fit a new CR2032, observing the correct polarity.
- Refit the cover and check the remote locks and unlocks the car.
Lost Key or Adding a Spare
A cell swap keeps the existing coding. A lost or broken key can only be ordered and programmed by a Genesis dealer with a diagnostic tool — there’s no owner sequence.
If a Fresh Cell Doesn’t Help
- Check the polarity — an upside-down cell won’t work.
- Hold the fob to the start button to start with a dead fob (it reads the transponder).
- Still intermittent? A receiver fault can store a code — look it up on autodtcs.com.
Frequently Asked Questions
What battery does the Genesis GV70 key use?
A single CR2032 coin cell.
Do I need to reprogram the key after the swap?
No — the coding is retained for a battery change.
Can I program a new GV70 key myself?
No — a replacement must be ordered and coded by a dealer.
The fob is dead — can I still start the car?
Yes — hold the fob against the start button and press, then use the mechanical blade to unlock.
If the fob stopped working after a battery disconnection, see our GV70 battery disconnect/reconnect guide.
