Twingo key fob battery issue

I experienced a similar predicament not long ago with my Vauxhall Corsa. The symptoms you describe – the insistent 'low battery' warning, the failure of the keyless entry system, the sporadic unlocking behavior – all mirror my own experience. Given the convergence of these indicators, it seems highly probable that the battery within your Renault Twingo key fob has indeed reached the end of its operational lifespan.

Interesting! So, with your Corsa, was it definitely just the battery? Did you try anything else before figuring that out?

Yes! In the instance of my Vauxhall Corsa, replacing the battery within the key fob proved to be the solution. Prior to undertaking this measure, I engaged in a thorough diagnostic process, scrutinizing the vehicle's central locking system for any aberrant behavior or error codes. However, upon discovering the ubiquity of the 'low battery' warning and the coincident failure of the keyless entry, I adjudged the battery to be the most probable source of the malfunction. If replacing the battery doesn't resolve the issue, I would recommend consulting a qualified technician to conduct a more exhaustive diagnostic analysis. Be sure to inquire about the cost; it might be worth it instead of tinkering!

Thanks for the detailed info! I took it to the shop as you suggested. Turns out it was just the battery in the key like we thought. Cost me 37€ all in to get it sorted. Appreciate the help!
