I have an older relative who is panicked over losing one of the keys. The dealer quoted her near $400, even more panick ensued! Evidently these keys are coded to the vehicle.

Assuming she doesn't find it soon, what's a solution to obtaing a new one w/o paying the dealer?

You can try getting a used fob off eBay or see if a locksmith has one stocked. The hard part is programming it to the car, many locksmiths do have access to the factory-level diagnosis system but getting a used fob to work is going to be hit or miss.

If the Ford/Mazda diagnostics system allows for the immobilizer portion of the PCM to be erased of all existing keys and then a new seed value(a big long string of numbers) to be written to it along with any keys/fobs to be programmed you might be lucky.

bdcardinal would know more about this.

It does cost that much. My dad bought a 14 Mazda5 former rental, only 1 key, and the used car dealer said bring the receipt for the extra key plus programming from the Maada dealer, it cost $500.

Keep looking for the other key. I've heard people who lost one keep the key inside the car and use a cut dumb key to get in and out, so that they don't have to pay $4-500 to replace it.

Locksmith.

I had a second key (just the key, I had two Advanced Key "fobs" but one was missing the removable traditional key with transponder chip)

It was $65 to have the addtional key made and added to my car.

I suspect you could get a locksmith to make a key for 1/3 to 2/3rds of what a dealer charges.

Edited to add. My car is a newly acquired 2012 Mazda3

oilBabe lost one of the keys to her former 2010 Altima, and having only one made me nervous, so for under $200, the locksmith was able to make a new Nissan Intellikey or whatever it's called.

On something that new, I doubt the aftermarkets got it covered yet

Especially if it's push button/smart key

Shop around dealers is my best advice

She swears it's inside the house. Her + son have looked 'everywhere' but no joy. I'm willing to contribute my keen eye + very bright light however she's not currently accepting visitors....unfortunately this just added more stress to her health problems. Finding it would be a great relief to her, however.

Therefore, it'll have to wait. Maybe they'll get lucky...

Anyone see anything remotely insane about a KEY costing $400?? Is it really necessary?

That is about right when you factor in labor for programming. There is only one option for the key on a CX-5 and it is sold as a fob and key. The vehicle is push button start so you cannot just get a key, you need the expensive fob. Mazda programming requires the technician to go to Mazda's tech webpage and enter personal data if you do it the correct way. We have locksmiths calling all the time wanting us to give them the required access code and we can only do it when the MDS (Mazda's scan tool) is hooked up to the vehicle.

The key will show up after you pay the $400 for a new one. It always turns out that way. Keep looking. Someone will find it.

They have trackers now for items like keys. Just attach the tracker to the fob. It's a good idea for those who lose things regularly.

Must be a very decent area to live, full of upright people. Sadly most of us live in metro areas. The one I am in is known for car theft.

People still steal newer cars, if anything the new proximity-based systems make it easier in some cases. There are devices on the black market that can grab the RF transmissions and guess via algorithms which code will grant access to the car and start it.

I read that she still has one working key. We have a local family hardware store that makes chipped key copies from your key for $125. I have heard that some dealers get up to $400 if you don't have a key or key number for them. Shop around. Ed

You've never owned a car in NYC, have you?

Chipped keys have silenced wailing alarms, while disarming would be joyriders and opportunistic thieves
