Trunk lock interchange
« on: July 05, 2009, 11:06:27 PM »

The lock on the Chrysler has been acting up a little, and I am considering replacing it.
 
Based on what I've seen online, and the two cars I've got, this seems to be the way the locks break down.
 
1964-65 use a key blank with no groove on the back side.  (these are harder to find to get copies made)

 
1966-68 use a key blank with one grove in the middle of the back side.

 
1969-72 use a key blank with one groove close to the edge of the back side.

 
All of these are locks held in with a clip.  1973 and newer uses the same key as 69-72 but the lock is theaded and held on with a big nut.
 
At some point they switched from a solid lock body, to one that has a clip on cover that provides access to the tumbler pins.

 
 
----------------------
Based on this, I think that I could use a 69-72 lock on my '65 and re-key it to match the one from the Dart.
Can anyone confirm that the later locks will fit?
If so, anybody got a lock they want to sell?

Did you try lubing the lock up?  PB Blaster will work it free in no time
 
Standard Ignition makes a universal Chrysler truck lock.  Other than the key, you can't tell the difference

I haven't tried anything in there yet, but PB Blaster is a great idea.   It's been working fine this week.
 
I'm still thinking about replacing it with a later style.  I only have one key, and it's looking pretty worn, and the '65 blanks are definitely less common.   Seems like it would be handy to have both trunks keyed the same.
