Firebird, what keys do you have originally with your Blazer??????

Reason I ask is we used to have a '70 NOVA, bought brand new, that had the square key for the ingnition and an oval key for the doors and trunk. All of the GM vehicles I've had after that all had the same key setup, square for ignition and oval for doors/trunk. We have members here that use the square key for ignition and doors. I just replaced all my locks, and of course they come with square for ignintion and oval for doors.

Confused

Thanks

We have several 60'-70's classic cars with original keys as well as the Blazer. I just checked a few of them, here is how they work on ours.

71 Ventura the square key works the ignition and the doors. The round key works the trunk and glove box. Original GM keys.

72 Chevelle is the same way, with original GM keys.

70 Firebird is the same way also with it's original GM keys.

56 nomad one key does everything, and you don't need an ignition key to start it if it's unlocked, talk about simple

My Blazer however, which also has the original GM keys is a bit different. The ignition is it's own key and works nothing else. The doors and rear hatch work with it's own key. My wife has the original GM keys at the moment, she drove the blazer to work today so I can't verify if her door key is round or square. But I can tell you I have my own set of GM keys for the blazer (probably cut as extras at some point many years ago, possibly could be an original extra set but seem to be too nice for that age) and they are both square, but one is ignition and the other is doors and hatch....I color coded them so I can tell them apart. I'll have to check my wifes original set when she gets home. But one thing is consistent with it,,,the iginition key is it's own, and the doors and hatch are another.

I checked my 79 chevrolet pickup, which I have original GM keys for and it differs from my cars. Square key is ignition only and the round key is used to open the doors and glove box.

At some point during the 70's and obviously on some models, GM changed the square key from working doors and ignition to working just the ignition only and the round key took on more responsibility (so to speak )

Thanks Firebird for checking all those keys. Wish I had a garage full of vintage metal.

Now that you said it and I've had more time to think back I do believe the NOVA was the same as your cars, square door/ignition key and oval trunk/glovebox key. Makes sense, when you use a valet you give them your square key to get in and move the car but you don't want them in the trunk or glovebox.

As far as the new set of door/ignition locks I bought they only came with a square key, not what I said in previous post. I should really get out into my garage more often.

Thanks for clearing this up for me, I can finally get a good nights rest.

Not a problem, your question really peaked my curiosity so I went out to check some of them. Now that my wife is home with the original blazer keys, I can tell you they are both square too, just like my pair.

You know, I never really thought about it at all until you brought it up.
