Hide behind the taint = tranny tuck.

 

In the original configuration, the "main" key should operate all locks- ignition, doors, trunk, glovebox, center console.

Some later-model Miatas (not sure when this started) also came with a Valet key, which opens the doors and operates the ignition, but does not open the trunk, glovebox or center console. Or maybe they were always like that and I've just never bought one that still had the Valet key.

 

My key works everything except the trunk. Bought the car this way. Hmm interesting nonetheless.

 

Funny story.

The key I've been using has a small crack in it and hasn't been opening the door lock without a fair amount of force. I'm a little worried to say the least.

So I grabbed one of the many keys I got from my dad who he got from the guy my dad bought the car off. Following me? This key opened the driver's door beautifully, I was seconds from swapping it with my cracked key, but since I had just read this thread I decided to try it in my center console and trunk. No dice.

TL;DR, my '93 did indeed come with a valet key.

 

I have a 90 which I got from my aunt (she was the original owner) and it came with a valet key. So looks like they all came with a valet key. My valet key does not have the black stuff (not sure what it is) around the top of the key from mazda, but my "main" key does. Of course with a copy all bets are off

 

FYI, any Miata-like key works in my green car. I had to valet it once and the guy tried to explain to me that one Miata key goes to the ignition, the other the trunk. I assured him that each key was for a specific Miata, he insisted I was wrong. That's why he's parking cars and I'm eating Petrossian in his shitty hotel.

 

Victor Petrossian? I went to school with him, I didn't know you two were dating.

 

Remove lock, take it to a locksmith. He will give it a good servicing. Problem solved.

I did this for the ignition switch on an impala last year and it cost $45. It works good as new with the original key.

 

stop shoving big black keys into your trunk lock all the time
