Features

Three things every car key should do.

Everything lives in one slim, precisely fitted case — no extra tag on your key ring, nothing to clip on.

Always findable

Built-in Apple Find My tracker. See where your keys are in the Find My app on your iPhone — around the house or across town.

Light in the dark

A bright LED at the end of the case, switched by a flush side button. Find the keyhole, your door lock or a dropped item at night.

Hear it, feel it

A buzzer and haptic alert help you locate your key when it's buried in a couch, a bag or a coat pocket.

How it works

Your key goes in. The smarts go behind it.

  1. The case holds your original key

    The top shell is shaped to your exact key model. Your factory key slips in whole — no opening it up, no swapping its board, no reprogramming.

  2. Electronics in a slim back pocket

    The tracker, LED, buzzer and switch sit in a thin tray behind the key, so the buttons and range of your key work as before.

  3. Tool-free battery

    A standard coin cell sits under a twist-off door. Swap it in seconds, no screwdriver needed.

Use cases

Made for everyday moments — and the bad days.

Find lost keys

Ring them from your phone or check their last location in Find My.

Light in the dark

Parking garages, late nights, dark driveways and front doors.

Stolen keys or vehicle

Location info that can help you and the authorities recover what's yours.

Teens and family

Peace of mind for shared family cars and new drivers.

Avoid a costly smart-key replacement

Modern smart keys are expensive to replace and program at a dealer. Keeping yours findable — and protected in a fitted case — is the cheaper path.

Patent pending

An original design, protected.

LumiFob's custom-fit case with an integrated light, tracker and alert is patent pending — a US provisional patent application was filed in October 2026.

Our long-term vision: tracker, light and haptic alert built into every new car key, through licensing with automakers.
