Question 1

What is the cheapest way to handle all-keys-lost on my 2000 Miata?

Accepted Answer

Call a mobile locksmith who can decode the lock or pull the key code through the VIN. On a 2000 Miata, all-keys-lost is not the complicated scenario it is on newer vehicles. There's no immobilizer to reset, no module to clear. A locksmith decodes the lock cylinder or traces the factory key code, cuts a new key, and you're back in business on site. No tow to the dealer, no waiting for parts to be ordered, no overnight. We come to you in the Loma Alta area and handle it in one visit.

Question 2

I had my key stolen. Can someone use it to break into or start my 2000 Miata?

Accepted Answer

Honestly, yes, they can if they have the physical key, because the 2000 Miata's security is entirely in the lock cylinders. There's no electronic key authorization to revoke. The practical answer if you've had a key stolen is to rekey the locks. A locksmith can repin the door and ignition cylinders to a new cut so the stolen key no longer operates anything. That's your best move here, and it's something that can be done mobile, at your location.

Question 3

Is there a hidden emergency blade inside a 2000 Miata key?

Accepted Answer

No. The 2000 Miata uses a traditional metal key, one piece, no fob housing around it. There's nothing to pop open. What you have is a standard cut key that operates the ignition and the door locks directly. If you're locked out, the answer is a locksmith with the right picks or a decoder, not a hidden blade. Keep a spare cut and stash it somewhere smart.

Question 4

Can any locksmith or hardware store cut a replacement key for a 2000 Miata, or does it have to be a dealer?

Accepted Answer

Most experienced locksmiths can handle it, and some hardware stores with key-cutting machines can too if you bring a working original for them to copy. The cleaner route is a locksmith who can pull the key code or decode the lock, because a direct copy of a worn original can introduce errors that make the new key finicky over time. Worn originals often have peaks and valleys that have drifted from the factory spec after years of use. A code-cut or decode-cut gives you a crisp key made to the correct depth specs, not a copy of a tired one. The dealer can do it, but you'll pay more and you'll need to schedule an appointment when a mobile locksmith can come to you in Loma Alta the same day.

Question 5

My 2000 Miata key turns hard and feels gritty in the ignition. Is the key worn out or is something wrong with the cylinder?

Accepted Answer

Could be either, and it matters which one. A worn key will feel gritty or resistant in multiple locks, ignition and both doors. If it's rough only in the ignition, the cylinder itself is the likely culprit. Miata ignition cylinders from this era are known to develop wear after heavy use, and sometimes the wafers inside get stiff or corroded. A little dry lubricant like graphite can help short-term, but if the cylinder is genuinely worn, a new cut key to the correct factory specs can sometimes smooth things out by giving the wafers a crisp edge to ride against. If it's still rough after that, the cylinder may need service or replacement. Either way, don't keep forcing a stiff ignition, because that's how you end up with a broken key inside the barrel.
