🔧 PRO TIP
The 2020 Challenger smart key runs on a CR2032, but a weak battery doesn't always kill the fob outright. What you get instead is intermittent range loss, the start button ignoring the fob from a normal seating position, or a key-not-detected warning that clears when you move the fob closer to the dash. Here's the thing owners miss: if the fob stops triggering the push-button start, press the fob body directly against the start button and push. There's a backup inductive reader built into that button for exactly this situation. It bypasses the standard RF path and reads the fob at close range. Swap the CR2032 first, seat the battery contacts clean, and retest range before assuming the fob or the vehicle security system has a deeper problem.

2020 Dodge Challenger Smart Key Replacement - Fast, Affordable & Professional

A sound engineer working a show at an outdoor venue near North El Cajon lost his fob somewhere between load-in and load-out. By the time the last piece of gear was in the truck, the fob was gone and the 2020 Challenger was going nowhere. Two of his crew members told him all-keys-lost on a push-to-start Dodge was dealer territory, period.

He found me and I drove out to the lot.

Push-to-start all-keys-lost is a different animal than adding a second key to a car that already has one working. There's no fob present to put the system into a pairing mode. The immobilizer has to be accessed through the diagnostic port, old key data cleared, and then new fobs enrolled fresh. I backed up the relevant module data before starting, then ran the all-keys-lost sequence. His replacement five-button fob, the factory FCC ID matching what Dodge specifies for this car, came up clean. Tested every function: lock, unlock, trunk, remote start if equipped, and the push-button start itself.

He was watching the whole time. When the engine fired in that parking lot, he just stood there for a second.

All-keys-lost on a push-to-start Challenger isn't dealer-only. It's tool-dependent. And the tools came to him.

Dodge Challenger Mobile Service FAQ

Real costs, no dealer surprises

How much does a 2020 Dodge Challenger smart key replacement cost?
Call for the exact number because it depends on whether you need one key, two, or an all-keys-lost situation. What I can tell you is that the dealer breaks it into separate line items: the fob itself, the emergency insert blade, and programming as a third charge, sometimes with a diagnostic fee on top of that. It adds up fast. With EZ Car Keyz it's one price that covers the fob, the cut blade, programming, and mobile service to your location in North El Cajon or wherever you're stuck. No surprise line items.
Is a mobile locksmith actually cheaper than the Dodge dealer for a smart key?
Does your price include cutting and programming, or are those extra?
My 2020 Challenger shows a key-not-detected warning but the fob battery is new. What's going on?
I bought a replacement fob online for my 2020 Challenger. Can I program it myself?
