2024 Mazda CX-90 Smart Key Replacement - Fast, Affordable & Professional
I got a call from a guy up near the CSUSM Area in San Marcos. He had found me through YouTube, watched a Mazda smart key job, and saved my number before he ever needed it. When his 2024 CX-90 started throwing a key-not-detected warning and the range dropped to almost nothing, he already knew the call to make.
He had already tried a new battery. It helped for about two days, then went back to the same behavior. That pattern usually tells me something before I even touch the car.
When I got there, I asked him which battery he had put in. He pulled out the packaging. CR2032. Close, but not right for this fob. The CR2025 is thinner, and putting in a CR2032 can seat unevenly against the contacts, which gives you intermittent connection rather than a clean failure. Sometimes it works fine. Sometimes it does exactly what his did.
I swapped in the correct CR2025, reseated the contacts, and closed the fob properly. Then I walked every function: lock, unlock, and the remaining buttons, checked door handle response, and ran three start cycles. All of it clean.
He did not need a new fob. He did not need programming. He needed the right battery seated correctly. That took less time than the drive over. The dealer route would have meant towing, a wait, and a bill that had nothing to do with the actual problem. He was back to normal before the parking lot got hot.

“I needed two keys made for my Honda Element. Friendly, fast, fair pricing, and far better than any other locksmith I have used in the area. Best service by far.”
“I lost my Honda Passport key and called EZ Car Keyz. He came out and made a new key in under five minutes. Legendary service.”
“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”
