Remote stopped locking your Fiat Talento (2016–2021)? It’s almost always a flat fob battery — and the good news is the van still gets you in and started using the key blade built into the fob.
The Talento was Fiat’s badge-engineered version of the Renault Trafic III, built from 2016 until Fiat Professional withdrew it in 2021; it revived the ‘Talento’ name Fiat had last used on a small van in the early 1990s.
Will It Still Start?
Yes. Even with a weak remote battery the key still starts the van — the immobiliser reads the key’s transponder, which needs no battery. A dead fob battery locks you out of the buttons, not the van.
Get In and Start
- Release the key blade — press the fob button and the metal switchblade flips out.
- Unlock the driver’s door with the blade (on some vans behind a cap on the handle).
- Start as normal — key-start vans just turn the key; keyless vans, press start with your foot on the brake and, if it doesn’t detect the fob, hold the fob against the start button.
- Replace the fob battery so remote locking works again.
Replace the Fob Battery
- Open the fob case at the slot with a small flat screwdriver.
- Swap the coin cell, matching the type and polarity marked on the cover — check the marking on your own fob rather than guessing. It lasts about two years.
- Clip the cover back firmly — a loose cover is a common cause of a fob that only works now and then.
There’s no owner resync step; the remote works as soon as a good cell is fitted. If the 12 volt battery was disconnected, the van’s ACCESS mode resets to default.
Frequently Asked Questions
Is the Fiat Talento just a rebadged Renault Trafic?
Yes — the 2016–2021 Talento is Fiat’s version of the Renault Trafic III, sharing its running gear with the Nissan NV300 and Vauxhall/Opel Vivaro. Fiat dropped it in 2021 when it switched to the Stellantis (Peugeot-based) Scudo and Ducato range.
Will my Fiat Talento start with a dead key fob battery?
Yes — use the built-in blade to open the door, then start as normal; the transponder works without a battery.
Where is the emergency key?
It’s the metal switchblade inside the fob — press the release button and it flips out for the driver’s door lock.
What battery does the fob take?
Check the type marked on the back of the cover — a standard coin cell lasting about two years. It varies by trim and year, so read your own fob.
Is it the same as a Renault Trafic?
Yes — as a rebadged Renault Trafic it uses the same fob and key, so the get-in-and-start method is identical across the Renault Trafic, Nissan NV300 and Vauxhall/Opel Vivaro.
