So, as for Mazda Key Fob. I only got one for my 2023 Mazda 3. The sales guy said if I go buy one, they will knock $20 off the programming ($169 my cost, so $189 is what they charge of you bring your own FOB. Thats in Charlotte, NC.) I thought that was reasonable, even though I thought I should have gotten two keys. Business guy said service lost it and they should buy me one....Keyfobs from the dealer are wildly overpriced.
Get a generic off of Ebay or Amazon and have a locksmith reprogram it. If you have a working one, they shouldn't have a problem.
I learned about this when I thought I would have to replace one of the fobs for my Mazda. I could have gotten a set of two 'generic' fobs for my CX5 for $150-200 and the automotive locksmiths I contacted wanted between $150-200 for programming up to two fobs. They all asked if I still had a working fob. I seem to remember my dealer quoting in the $500 range for ONE fob and programming.
Anyway, I opened the key and got the part number, FCC number and some other number (forget what it was.) Searched eBay for part number and found several vendors that had it (inlcuding all the correct FCC numbers, etc.) Found one fairly close to me that had like a million reviews. Cost me $24.99 delivered. Took it to Mazda and they programmed it, and cut the key inside. Went to pay and the guy handed me the invoice and said "Have a nice day." No charge. I don't know if sales guy took care of it or the business guy, but they did cover it.
