OT: Kinda "Sorta" : Key Code Related 1936-1966 GM Vehicles
Posted by: Caraholic4life ()

Have any of you wondered if you could figure out the Key Code for your 1960-1966 Corvair or other 1936-1966 GM Vehicle based on decoding the cuts and looking through the code book? I have and it is close to impossible in my opinion, as i was never successful at it.

I was a bit bored the other evening and decided to figure out an easy way to do this and took on the project just for the tedium of it.

I set up an Excel Spreadsheet and proceeded to enter all 1500 Key Codes and their Six cuts in Code Order. Yes this took several hours.

Once that was accomplished, I did a "Data Sort" to rearrange things into the Key Cut order along with the corresponding code.

The code with the shallowest cuts across the board is 9356 having 222245 cuts.
The code with the deepest cuts across the board is 9151 having 555532 cuts.

Now, with all that said....
If any of you know what the six cuts on your keys are and would be interested in knowing what the key code for it might be, I can now look at my spreadsheet and let you know.

Keep in mind this is for the B10 & B11 style Octagon & Pear Shape head keys (Groove 15) prior to 1967.
Doing this for the later Letter Code Keys is more than I am willing to take on.

Rather than do this publicly, a Private Message would probably be the safest method of getting this done.

Interesting -- I have a couple of the Clark's repro locks and keys and they DO NOT have codes on them. It would be nice to have a code in case I need to have keys cut.

When I get to it I'll drop a PM.

Is the code printed on the side of the cylinder?

First year for a B10-B11 blank is 1935.

Neat!

Interesting side note, I replaced my missing trunk lock with a generic one off the internet. Not from Clarks or California or anything like that.

I keep all my keys on a big tangle of chains that I call my key archive. Seriously, I still have keys to the original apartment I had when I first married my first wife in 1996. And the keys to a poor little Volvo I owned in Alaska. Not that I would expect them to work.

Just for the fun of it, I went to my torver section and tried all the trunk keys. Two of them worked! I'm very curious as to what the odds of that are.

Eric -

I've got a huge ball of Corvair keys - I have a very high success rate at finding keys to fit locks / gloveboxes / ignitions of cars I buy, missing keys, or lock sets I find.

1500 unique cut depth codes. Millions of cars. so, 1 out of 1500 initial odds, then add to that keys that are worn, so they might do the lock they were made for, and also the lock with one or more lower cuts with jiggling.eye popping smiley

Well, probably not what you want to hear.

I would take the keys to a hardware store and have a duplicate set cut - before they start to wear.

That is what I have done with my Corvair keys over the decades.

I would strongly advise AGAINST having keys duplicated at a "Hardware Store", especially the big box variety.

I say this for several reasons, these are the top two reasons:

Often the individual making the duplicates does not have any proper training.
Often the key machine is not checked for accuracy once it is purchased.

The rare exception these days might be in an old family owned Hardware Store where the people actually have some training and maintain their equipment to stay within specification to insure accuracy.

Yes, you are correct. I was going by memory and didn't verify the year range first.

Initially I was going to put down 1960-1966 Corvair's but decided to offer a broader range for those who might have other GM vehicles.

In my defense, these codes still work for 1936-1966. grinning smiley

You don't actually need the 4 digit code. All you need is the 6 digit code for making the key. I believe the first few pages in the '61 shop manual tell you how to measure the key to get the code.

Thanks for the warning.

I was being a bit flip because I did not think that key shops had a physical store anymore.

I looked ant the one I used years ago is still in business. I just never drive that section of the street.

Confused, Matt

I do not have a problem. I was just commenting on having keys made.

I have not had keys made in many years. I checked and I still have fresh backups for my Corvairs. Except my wife has been organizing (split keys / locks into two drawers) and It looks like I need to group things better.

Should delete this post - serves no real purpose. Thanks.

I rode home from the hospital when I was born in a 35 Chevy coupe, and I remember my Dad telling me it was the first year for the new key design.

He said that when he was a kid that if someone lost a key or was locked out of there car at church, everyone with a GM vehicle would bring there key and try it. He said 90% of the time they would find a match.

I had a similar story but it only involved two people.

At the time, probably in 1966, my Dad had a 1965 Corvette and a friend with another Corvette was visiting.

One of them, I can't remember dropped their keys in the snow and could not find them. They eventually tried the keys for the other Corvette and they worked.

Knowing what I do today, I know the chances of that happening are slim but back then I can't help but remember thinking that all Corvettes must use the same keys.
After all, I was only about ten years old at the time.
