Question 1

Are you licensed and insured to work on Mazda vehicles?

Accepted Answer

Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services (BSIS License LCO#6792) and carries full liability insurance. For a 2009 CX-9 smart key job, that matters because this vehicle uses a security system that requires proper diagnostic equipment and authorized key data to program correctly. Not every locksmith who shows up in a search result carries the right tools or credentials for this generation of Mazda. We do, and we can walk you through exactly what the job involves before we arrive.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Scam locksmiths follow a pattern that Mazda owners know well from forums: a low quote over the phone, a generic fob that may not pair cleanly, and extra fees added on site once they have your keys. Some deliver a fob that appears to work but throws a key warning on the dash within a day or two because it was never properly registered to the vehicle.

A real automotive locksmith gives you a firm price for your specific vehicle before showing up, explains the process, and has a verifiable business presence you can check. We have over 100,000 followers across our YouTube and TikTok channels showing the actual work, on actual vehicles, with no bait-and-switch. You can watch a fob programming job before you ever call us.

Question 3

Will the replacement key work exactly like the original?

Accepted Answer

Yes. A properly programmed smart key for the 2009 CX-9 registers to the vehicle's immobilizer and communicates the same way the factory fob does. The engine starts, all four buttons respond, and the security system recognizes it as a valid key. We test every function on site before we hand it to you.

One thing worth knowing: a key that was programmed with the wrong fob for this year, or one that was paired incorrectly, can leave a key-related warning showing on the dash even if the car starts. That's a sign something wasn't done right. We use the correct fob for this vehicle and verify the result before we leave, so you're not finding out about a problem the next morning.

Question 4

I only have one key left for my 2009 CX-9. Is it worth getting a spare before I lose it entirely?

Accepted Answer

Yes, and the gap between add-a-key and all-keys-lost is significant on this vehicle. When you have one working key, I can register a second fob alongside it without touching the existing security memory. The original keeps working exactly as it did.

When that last key is gone, the job becomes an all-keys-lost reset. The security memory gets cleared, new keys get enrolled from scratch, and the process takes longer because of a built-in timed sequence in the programming cycle. It's a bigger job, and it costs more. Getting a spare while you still have the original is always the smarter move, and it takes less time on site.

Question 5

My 2009 CX-9 fob range dropped off suddenly. The car starts fine but I have to be right next to it for the buttons to work. Is the fob dying?

Accepted Answer

Short range like that on a 4-button fob usually points to the CR2025 cell being low, not a dead fob. The CX-9's smart key system will still start the car when voltage drops because the vehicle can read the fob at close range or through the backup antenna, but the remote functions need a stronger signal and those go soft first.

Swap the CR2025 before assuming anything else is wrong. If range comes back, you're done. If it stays weak after a fresh cell, the next thing to check is whether the fob has any physical damage or moisture inside. A cracked housing lets humidity in and corrodes the contacts over time. That's a fob replacement, not a programming issue.
