Different Door Keys

Post by erco »

My '67 Monza has always had different keys for driver door (also the ignition key) and passenger door. Kind of a pain to have 2 different keys. My driver door key doesn't even really fit in the passenger door. I always assumed the passenger door lock was haphazardly replaced at some point. I just called a locksmith to inquire about re-keying the passenger door lock and he told me that GM did that on purpose from the factory.

True or false?

I wouldn't use that locksmith. GM did not do that.
I would guess someone replaced the driver's lock and ignition switch at some point.
What letter do the keys have on them? That will tell you if they are even from the right year. '66 and prior have the same key blanks but in '67 they started rotating them every 4 years. My old brain can't keep all the years and letters straight but they never used a different blank for the driver vs passenger door or differently cut key for that matter. You can check the key cut against the number on the lock cylinder to see if it has been changed.

From 1936 through 1966 GM used the number 15 Groove on their key blanks.
The blanks were made by Briggs and Stratton.
The Hex Head part number is 32318 from B&S, H1098LA from ILCO, and B10 from Curtis and others.
The Pear Head part number is 32319 from B&S, O1098LA from ILCO, and B11 from Curtis and others.
In 1967 GM went to the "A" key for ignition (Rectangle head) but also used the old style Octagon head.
In 1967 GM went to the "B" key for the glove box (Oval Head) but also used the old style Pear head.
In 1968 GM went to the "C" key for ignition (Rectangle head)
In 1968 GM went to the "D" key for the glove box (Oval Head)
In 1969 GM went to the "E" key for ignition (Rectangle head)
In 1969 GM went to the "H" key for the glove box (Oval Head)
In 1970 GM went to the "J" key for the ignition (Rectangle head)
In 1970 GM went to the "K" key for the glove box (Oval Head)
In 1971 GM went to the "A" key for ignition (Rectangle head)
In 1971 GM went to the "B" key for the glove box (Oval Head)
They continued rotating the blanks from year to year until they went with the double sided convenience key that could be inserted either way.

I just checked my late '66 Sport Sedan. The hex head key opens both doors and the ignition. The pear head key opens the trunk and glove box. Both blanks are the same style as all previous year Corvairs.

One more question for the key master:

I need just the trunk lock shaft/rod for my '67. Clark's only lists one for 60-64: http://www.corvair.com/user-cgi/search.cgi?part=C1232

That rod looks just like this one for a '67 GTO:

NAPA sells the whole lock kit for under $10: https://www.napaonline.com/en/p/ECHTLK11

Seems like a part Dorman would sell.

Give one of the Corvair vendors a call. I'm sure you'll find one. I have several laying around but I don't know what they fit.
