Question 1

My key broke off in the ignition. Can you get it out?

Accepted Answer

Yes, broken key extraction is a standard call for me. I carry the tools to pull a broken piece out of the ignition cylinder without damaging the cylinder itself, which matters on a Miata because the ignition housing sits in a tight column and a botched extraction can turn a simple job into a cylinder replacement.

On the NB-generation Miata, owners report the key snapping near the tip after years of the same insertion angle and worn cuts catching on the cylinder wafers. Once the piece is out, I cut a new key to your vehicle on the spot and you are done.

Question 2

What kind of key does the 2003 Mazda Miata actually use?

Accepted Answer

A straight metal key, cut to your car, nothing else. No remote, no fob, no battery to replace. The same key works the ignition, the driver door, and the passenger door. Replacement is a cutting job, not a programming job.

Question 3

My Miata will not start and I am getting some kind of warning. Could it be the key?

Accepted Answer

On a 2003 Miata with a standard metal key, a no-start usually points somewhere other than the key itself. Check the obvious first: is the key turning all the way, or is the steering column lock binding it? That is a common one on these. Push the wheel left or right with light pressure while you turn the key and see if it frees up.

If the key turns freely but the car will not crank, you are looking at the battery, the starter circuit, or the ignition switch, not the key blade. If the key feels sloppy or worn and the cylinder is not catching cleanly, that is when a worn key or worn cylinder comes into the picture. Bring me the key and I can tell you in about thirty seconds whether the cuts are still good or if it is time for a fresh one made to code.

Question 4

I lost my only key for my 2003 Miata. Do you need the car to make a new one, or can you work from the door lock?

Accepted Answer

I can work from the lock. On these Miatas the door lock cylinder can be decoded directly, which means I read the depth and spacing of the cuts right out of the lock and use that to cut a working key. No original key needed, no towing to a dealer.

If the vehicle identification number is available I can also pull the key code through the proper data channel and cut from code instead. Either way, all-keys-lost on a 2003 Miata is not a production. I show up, I decode or code-cut, I test in the ignition, and you have a working key. The dealer route on a lost-key situation like this tends to take days and cost noticeably more.

Question 5

The key is getting hard to turn in the ignition. Is that the key wearing out or the cylinder?

Accepted Answer

Could be either, and on a 2003 Miata that has been driven daily for over twenty years, both are worth looking at. A key that has been copied from a copy loses sharpness in the cuts over time, and a worn key will drag in a cylinder that a fresh-cut key would turn cleanly.

The cylinder itself is also a real possibility. The NB Miata ignition cylinder sees a lot of cycles and the wafers inside can wear unevenly, especially if the key ring is heavy and puts side load on the key while driving. If I cut you a new key to the original code and it still drags, the cylinder is telling you something. Either way, catching it before it gets to the broken-key stage saves you the harder job.
