Keys and locks.

Door cyls.,trunk & G/box Cyls. should have the lock code on them. You;ll have to remove all of them to find it. If you can't find them, while you have them all out, a locksmith, will be able to re-code all the cyls. to ign. key for doors & trunk key to G/box.

Your glove box warranty book with protecto plate also has the key code to your car on the last page. Four numbers like 9452 size of pins within tumblers. I'm with Pete, take'm to any locksmith, can key cylinders even without keys. Original key blanks are still available.

Thanks! That's awesome news to hear! I have to tear into everything to redo the harness that's in it so I'll tear the locks out and take a look as well!

You could also get "lucky" & have the Original' keys that "might " still have the code on the "punch out' tab on key!!! My 52 had a original set of keys with tab still there, & so did the 64 Catalina!!! But someone may have changed something along the way on yours?? pete

That's quite helpful! I am starting to get the impression someone has changed out the door locks previously as I find the passenger side has been installed slightly incorrectly. If I get the key codes can I get new door lock cylinders to match my ignition key?

I believe a good locksmith should be able to do that.

I'm not sure if anyone answered your question about what key should open what. As you state on your 70 Bonneville (same as my 70 Canadian Pontiac's), the square ignition key does the doors, and the round trunk key does the glove box.

Hopefully one of the Carl's will chime in re 1966 on what key does what.

I think the original keys would have been "Briggs & Stratton", and good locksmiths should have them. I'm not sure if they're different each year, but I think so. Similar to 1970 uses a J code square ignition key, and a K code round trunk key. 69 ignition key was E code, 71 ignition key was A code, and 72 ignition was C code.

After all of the above I'm guessing that original coded keys will work on everything else besides the ignition. Ignition is the one most prone to failure. If I'm right get the original codes and a set of keys cut then have the ignition tumblers set to match the original.
You do know how to remove the cylinder from the ignition switch?????

You are almost correct in your guess; trunk works in glovebox, ignition works in ignition but nothing works in doors. Ignition doesn't look too hard to remove, have done tons of column style ignition replacements but this is my first in dash style so if there is any special tricks to hit, feel free to enlighten me!

It's been so long since I had a 66 GP on the road I forget for sure!

I would say door/ignition is the square key, trunk/glove box/console is the round key.

As I seem unable to navigate your site to find anything related to keys, would you be able to provide me with an ignition/door lock combo that work off the same key?

The most simple suggestion to you without interfering in weather or not you purchase any items, would be for you to remove the drivers door lock and the ignition cylinder to retrieve the stamped codes off of them... The door cylinder is self explanatory while the ignition cylinder too is fairly simple.... Turn the ignition back to accessory, find yourself a normal sized paperclip... Unwind the clip, insert into the little hole that's present in the cylinder to push on a detent plunger that's there... When you push on the plunger, you will feel the spring action! While pushing the plunger, twist the key a little more to the counterclockwise position and remove the cylinder and key.... There you will (should) be able to read the code.... As previously stated, a 4-digit number....

I code, have keys and do this often... Let us know what you find!

I thought '66's had the octagonal ignition key and the round key for trunk/door/glove box/console. They're key blank B10 and B11 if my memory serves me.
The later, rectangular ignition keys usually work if you can't find the earlier blanks.
What year did they start using the rectangular ignition keys anyway? I thought it was when they moved the ignition switch to the steering column in, was it, '68?

1969 was when the ignition went to the column, and with it the larger square/rectangular key.

I know it's been a while so figured I would update with my progress! (Life seriously got in the way)

Pulled out all the locks to find a complete mismatch of numbers.. none were the same and each lock was keyed differently. Ended up ordering a complete set for a 66 Impala to find out that most were close... but not quite right.

The trunk was completely out to lunch. So today I tore all the locks out, replaced the ignition and door locks which were identical, disassembled the glovebox lock and swapped latch arms, and disassembled the trunk locks, swapped lock cylinders out, and reinstalled new cylinder inside old mechanism back into trunk.

I can now lock everything! Key is hexagonal and don't think it's correct, but I am not sure if the square and pear seat I had were period correct either.

With my car being in the driveway as my garage still isn't finished from the fire I figured this needed to get done so I could worry less about breakins. Not sure if there is a set out there that's identical to the Grande Parisienne but you can modify an Impala set to work I found.

Had to swap latch arms by removing spring, pressing in and back to slide arm pivot out of groove, then up and out. Reversal to reinstall.

Impala trunk lock is held in place similar to door locks with forked spring clip to hold in place. GP used two 7/16' nuts to hold in place so removed the lock cylinder and swapped internals. The Impala lock cap did not survive this process but wasn't needed.

Old mechanism with new cylinder. Replaced key door springs and key door as well when swapping, cleaned up cap that goes over top from previous owner overspray and reinstalled. All worked perfectly.

Great information and thanks for posting it in such good detail Mark.

It's ingenuity like this that makes the old car hobby fun.

MarkV · Addicted!

Not a problem Carl! I'm more than happy to spread any bit of info I come across! I do enjoy tinkering and it is rather fun to find ways to make things work, just wish the Canadian Pontiacs were a little more... standard! Haha

Seems to me you had wiring grief way back when. Have you worked on that part of it yet?

MarkV · Addicted!

Yea, I've got most of that taken care of.. will just be a few odds and ends to clear up... until I decide to start this manual conversion which will open up a whole new can of worms with reverse lights and starter interlocks... hopefully will go smooth tho!
On that topic.. couldn't find anyone reproducing the console door lock so will most likely never get that lockable!

4SPEED427 · A Poncho Legend!

Are you doing the interlock just for safety reasons? You do know they never had anything like that originally in 66?

MarkV · Addicted!

Yea, there is going to be a few things a little different from original with the wiring and operations. Will eventually be running an electric fuel pump so there will be an oil pressure killswitch with that as well as I want to interrupt the starter line with the clutch pedal just for safety reasons. Last thing I need is accidentally putting the car through the far end of my garage when trying to start it!
