2020 Mazda CX-3 Smart Key Replacement - Fast, Affordable & Professional
The OEM versus aftermarket question on 2020 Mazda CX-3 keys deserves an honest answer. OEM Mazda keys come from the factory supplier with the logo and the price tag. Aftermarket keys use the same blade profile, same chip type, same button layout, and same circuit board design. The daily-use difference is zero when the aftermarket blank is quality sourced.
An English professor at the bookstore in Escondido asked me straight whether the key would be "as good as dealer." She had a 2020 Mazda CX-3 and wanted a spare she could trust daily, not just an emergency backup. Fair question.
I carry aftermarket blanks tested across hundreds of Mazda jobs. The blade is the same MAZ24 profile cut to spec. The transponder chip is the same generation the immobilizer expects. I decoded her door lock with my MAZ24 Lishi, cut the blade, and programmed the chip through OBD. Her key, FCC ID WAZSKE11D01, was a 4-button remote. The aftermarket shell has the same button feel and fit as factory.
Her total was $257. Dealer charges $443 for the OEM version. Where aftermarket goes wrong is cheap blanks with brittle shells. I test every batch before it goes in the van.

“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.”
“About 15 minutes after calling, he was already at my home. I had lost my original Ford key and he made and programmed a new one on the spot. Very fast, very professional.”
