If the keycard for your Renault Captur Mk1 (X87, 2013–2020) only works from up close, won’t lock the car, or the hands-free start has become unreliable, the keycard’s coin battery is almost always the cause — and it is a quick change. This guide shows how to renew the Renault keycard battery and what needs a dealer.

First, Rule Out the Battery
A weak keycard battery is the number-one reason a Captur remote becomes unreliable — short range, needing several presses, or hands-free entry/start failing. The Renault keycard uses a coin cell (commonly a CR2025 — check yours when you open it).
Replacing the Keycard Battery
- Press and hold the release button and pull out the emergency (mechanical) key from the keycard.
- Remove the battery cover revealed by removing the key.
- Lift out the old coin cell.
- Fit the new cell observing the correct polarity (the same way the old one sat).
- Refit the cover and the emergency key. Test the keycard.
After a battery change the keycard keeps its programming — no re-pairing needed.
Lost Keycard or Adding a Spare
The Captur cannot have a keycard programmed at home. A lost or extra keycard must be ordered and coded by a Renault dealer or an auto-locksmith with the right equipment — it is security-locked to the car. The home job is limited to renewing the battery in a card that already works.
If a Fresh Battery Doesn’t Fix It
- Check the cell type and polarity — a coin cell fitted the wrong way gives no response.
- Use the emergency key (hidden in the card) to unlock the door, and hold the keycard against the marked spot on the dash / in the reader to start with a flat battery.
- Still nothing? A receiver or card-reader fault may be involved — check the code on autodtcs.com.
Frequently Asked Questions
What battery does the Captur keycard take?
A coin cell, commonly a CR2025 — open the card to confirm before buying.
Do I need to reprogram after changing the battery?
No — programming is retained. Just fit the new cell the right way round and test.
Can I program a new Captur keycard myself?
No — the keycard is security-locked and must be ordered and coded by a Renault dealer or locksmith.
How do I start the car if the keycard is dead?
Hold the keycard against the marked location (often by the steering column / start button) so the car can read it, then press start.
If the keycard stopped working after a battery disconnection, see our Renault Captur battery disconnect/reconnect guide.
