If the key fob on your Lynk & Co 01 (2017–2024) has gone weak or the 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.
- The fob’s own mechanical key blade.
Replacing the Cell
- Pull out the mechanical key.
- Remove the key cover, then the button-cell cover.
- Renew the cell with a CR2032, observing the correct polarity.
- Refit the cell cover, key cover and mechanical key, then 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 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.
- Use the mechanical blade to unlock the door in the meantime.
- Still intermittent? A receiver fault can store a code — look it up on autodtcs.com.
Frequently Asked Questions
What battery does the Lynk & Co 01 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 key myself?
No — a replacement must be ordered and coded by a dealer.
The fob is dead — can I still get in?
Yes — use the mechanical key blade to unlock the door.
If the fob stopped working after a battery disconnection, see our Lynk & Co 01 battery guide.
