🔧 PRO TIP
The 2017 Fiat 500x uses a 4-button smart key running on a CR2032. The fob houses an emergency insert blade that most owners never notice until the battery dies and the push-button start stops responding. On these, a weak battery doesn't always kill the fob outright. Instead you get inconsistent range, the vehicle security system showing a key-not-detected warning on the cluster, or the door handles ignoring your approach entirely. Swap the CR2032 first, seat it firmly against both contacts, and retest from about 30 feet before assuming the fob itself is dead. Also worth knowing: adding a new fob to this vehicle requires diagnostic equipment at the OBD port. There is no ignition-turn or button-sequence self-programming trick on this system. If someone sold you a blank fob online and told you to follow a YouTube sequence, that sequence won't work here.

2017 Fiat 500x Smart Key Replacement - Fast, Affordable & Professional

I got a call from a guy at the pickleball courts near Grossmont in La Mesa. He'd been playing a full set, came back to his 2017 Fiat 500x, and the fob just wasn't waking the car up. He pressed the start button, got a key-not-detected warning on the dash, and stood there in the parking lot doing the thing everyone does: pressing the button harder, like that changes anything.

He figured it was the battery. He was partly right. The CR2032 had enough juice to register with the car sometimes, but not reliably. That's the thing about these fobs on the edge of battery death. They don't fail clean. They fail sideways. Works twice, skips once, works again, then leaves you standing outside a car that technically knows your key exists but can't decide how it feels about it.

I pulled in, popped the fob open on the hood of my van, and the battery was original. Still had voltage, technically, but these cells get lazy before they go fully flat. Fresh CR2032, firm contact on both terminals, and the fob came back sharp. Range was solid, all four buttons responded, and the key-not-detected warning cleared immediately.

Then I did the part he didn't expect. I walked the perimeter. Tested lock and unlock from the driver side, from the passenger side, from behind the car. Ran all four buttons individually. Started the car, shut it off, walked away, started it again. Did that three times. He was watching me like I was doing something unnecessary.

I told him the extra five minutes isn't about doubting the fix. It's about knowing the fix held across a real use pattern, not just one button press in ideal conditions. He said he'd never had a locksmith do that before. I told him most don't.

The dealer would have had him tow the car in and wait for an appointment. This was done in his parking spot, same day he called.

Fiat 500x Mobile Service FAQ

Real costs, no dealer surprises

What is the most affordable way to handle all-keys-lost on my 2017 Fiat 500x?
Call a mobile locksmith before you call the dealer or a tow truck. All-keys-lost on the 500x requires connecting to the OBD port, reading the immobilizer data from the body control module, and registering fresh fobs to the system. It sounds involved, but I do it on-site at your location. No tow, no dealer appointment, no sitting in a waiting room. The price I give you on the phone is the price you pay. Dealers quote significantly more for the same job, and that's before any towing cost gets added in.
Can you wipe out a lost or stolen key so it can't be used on my 500x anymore?
Does the 2017 Fiat 500x smart key have a hidden emergency blade inside it?
My 2017 Fiat 500x starts fine but the key-not-detected warning keeps coming back. Is the fob failing?
I bought a replacement fob online for my 500x. Can I program it myself or do I need a locksmith?
