Seicento key fob battery issue

Hi, I've got a 2005 Fiat Seicento with a gasoline engine, and the key fob is throwing a 'key battery low' warning. Now, the keyless access is completely dead, and I even pulled the error memory which confirms a low voltage issue with the key. Unlocking and locking the car is becoming a real pain. Mileage is 116933 km. Anyone else had this?

A 2005 Fiat Seicento owner experienced a 'key battery low' warning, leading to a complete failure of the keyless access system. The issue was confirmed by error memory indicating a low voltage problem with the key. While initially considering a simple battery replacement, advice from another owner suggested the possibility of needing key reprogramming. Ultimately, replacing the key fob battery resolved the issue, restoring functionality.

I had a similar problem with my Seicento. Keyless entry stopped working altogether. Have you tried anything besides reading the error codes?

Beyond checking the error codes, I haven't done much else. I assumed it was a simple battery issue, but thought I'd check if there's anything else I should consider before replacing it. What did you end up doing?

In my case, replacing the battery didn't solve the issue. The workshop had to reprogram the key. So yes, it might be just the battery, but better be prepared to visit the workshop. Good luck.

Thanks for the info! Turns out it was indeed just the battery in the key fob. A quick replacement at the workshop cost me 37€ and everything's working perfectly again.
