CX-90 keys & remotes
Remote buttons can work while proximity does not
For your model
The 2025 CX-90 manual describes a key power-saving function that switches off advanced keyless entry and pocket-or-bag starting while leaving button remote operation available. That behavior is different from losing the registered key.
Before arranging the work
Tell us whether buttons, door-handle access and starting each work. Include the year and whether the vehicle is a PHEV so the correct instructions and replacement are checked. Keep a retained remote available even when its indicator does not flash.

Key questions
Do working CX-90 buttons prove the proximity system must also work?
No. Mazda’s 2025 manual describes a power-saving setting with different behavior for those functions. Check your vehicle’s instructions and report which functions remain before buying a new remote.
