In my 46 Chevy. truck.
How do remove the cylinder/key to a new key?
Is there a code for a new copy?

Is the key the same door lock and the lock box the same?
Thanks,
Harold

The door lock and ignition switch use the same key. A second key is used for the box lock.

I am unaware of a code number stamped on the locks. But, from the factory and when new there would have been a number stamped on the key on a small removable tab attached to the key. Those tabs would have been removed by the new owner or upon delivery by the dealer. That number would have been or was recommended to have been recorded for future reference as needed.

A locksmith might have a ring of keys, or know of someone that might have such, that should be able to help?

There is a number on the lock inside, secret disassembly steps required if you lost key and didn’t write it down
It’s 4 digits
Canada and USA share the same lock number lookup table
With those 4 numbers your locksmith can cut a key without seeing the lock or the truck
My local locksmith took apart a glove box and ignition lock for me in Canada
Emailed a guy he knows in the USA who looked up the key machine settings for him and he produced a perfect key for my grandpas old farm truck.

On the AD trucks, there's a code on the door lock cylinder. If you can pull the door lock out, you should be able to get the code off it.
The codes were the same from 1935 thru 1966. More info in this post. Scroll up 2 posts from there and DADS50 posted a pic of where the code is on the door lock.
Most any locksmith (not the key duplicators at the hardware stores) can cut you a key if you have the code.


If all else fails, send me your ignition lock and I can see if I have a key that will fit and send it back to you. I've collected about 150 different keys.

Great info on the number location!

It will require removing the entire lock assembly from the door, which is more hassle but not a problem.

You shouldn’t have to remove the latch, just the lock which is held in place by a retainer located under the weatherstrip.

Could be. But, here’s some photos from the assemblies on my ‘46.

The piece at the yellow arrow pulls out to release the lock.

You are right Kevin, but in his case the latch mounting plate is overlapping that clip. Unless he is going to do some "bending", latch plate at least needs to have mount screws loosened/removed to push it out of the way to pull the clip and then reinstall.

Sorry Sparky!

Maybe there's enough slop in the slot that the clip can be pried out from behind the latch plate. On my truck, there were prongs (or barbs) on the spring steel clip that keep it in place. Maybe the one on Sparky's truck is aftermarket without the prongs.

I could be all wet on this install, but having had that lock assembly on and off multiple times when doing the restoration because of assorted problems with more than just the lock, this set up was the only one that seemed to work??? At least it has so far. If another option is better/correct I’m all for making a change.

Sparky, Here's the same style door lock retainer that's on my truck. Link

The filling Station also sells a universal lock retainer clip Link

Notice that both have a smaller portion that shows on the outside edge of the door. Yours appears to be much bigger there, and enough to lap under the latch plate.

Agreed. There is a big difference between these. Off hand I don’t recall which vendor I used. I don’t think it was either of those listed.

Thank you for replying to your replies.
All instructions are appreciated

I moved to my truck and try the ignition keys. Can the cylinder get paired with another cylinder?

Harold, you could probably take it to a locksmith and have them pick it open in order to get the cylinder out. I'm not sure if the pins for matching it to your key are still available for the Briggs & Stratton lock cylinders. They could drill out the cylinder and replace it with a reproduction cylinder, which are widely available, and you could get a matched set if desired. I don't know what the quality would be as I haven't bought any.

I had a locksmith re-pin two locks on my '52 GMC about 8 years ago so both doors, the glove box and the ignition were all the same.
