🔧 PRO TIP
The 2017 Hardtop 4 Door is F55 generation, running the CAS4+ (Car Access System 4 Plus) module with a Hitag Pro 49 transponder chip inside the NBGIDGNG1 fob. A dying CR2032 throws "No key detected" or "Key invalid" on the center display, and the Comfort Access touch sensors on the door handles stop responding before anything else. Swap the battery first, but make sure the contacts inside the fob shell seat flat. A cockeyed CR2032 mimics a dead key perfectly.

2017 MINI Hardtop 4 Door Smart Key Replacement - Fast, Affordable & Professional

Got a call from a guy at Pacific View Mall in Ventura. He had finished shopping, walked out to his 2017 MINI Hardtop 4 Door, grabbed the door handle, and nothing happened. Comfort Access just dead. He pulled the fob out of his pocket and hit the unlock button manually. That worked. Car started fine too. But the touch sensors on both front handles acted like they didn't exist.

He sat in the parking lot for a while Googling it and convinced himself the CAS4+ module was failing. Already had a dealer quote in his head and was not happy about it.

I got there and started simple. Popped open the NBGIDGNG1 fob on his hood. The CR2032 had maybe a whisper of charge left, enough for the button press at close range but not enough for the passive polling that Comfort Access needs. That passive signal is always broadcasting, and it drains a weak battery before the active buttons stop working.

New CR2032 in, contacts seated correctly, and I walked him through the test. Left handle, right handle, hatch button, start button, lock on walk-away. Everything came back. He kept opening and closing the door like he was testing it for a fifth time.

No module issue. No programming. Just a battery that was too weak for the passive side of the system. Took about ten minutes and saved him a trip to the dealer.

“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”

MINI Hardtop 4 Door Mobile Service FAQ

Real costs, no dealer surprises

What battery does the 2017 MINI Hardtop 4 Door smart key use, and can I swap it myself?
CR2032. You can do it yourself. The NBGIDGNG1 fob has a small release on the back to slide out the emergency key blade, then the case pries apart at the seam. Pop the old battery, drop in the new one positive side down, and snap it shut. No reprogramming needed after a battery swap. The car keeps the fob's registration in the CAS4+ module memory. If the key still acts up after a fresh battery, the issue is somewhere else and that is where we come in.
