The keys that came with the 1963 convertible I got in July don't match the door locks. I probably won't lock the car often (or ever) because I've heard too many stories of tops getting cut to steal a couple bucks worth of change. However, I live in fear that someone will lock me out of the car. Plus, I just want to have working locks. I think I can get replacements with keys cheaper than getting the lock re-keyed.

I've read that there are short and longer lock cylinders and that they are not interchangeable. Is there any way to know which ones I've got short of taking the door apart? I know I will have to take it apart to install the replacements, but would like to do the dis-assemble and re-assembly at the same time if possible.

Also, any tips on changing out the locks. I plan to replace all  the locks in the car (2 doors, trunk, ignition, glove box).

Any and all help and tips appreciated!

IF you leave the convert open and empty out any valuables (to the trunk ) which I am sure is the best policy with a convert having owned one always my entire life and  have had locked ones vandalized by cutting trough the top ( in NY ) 

The odds are very slim  to none —-if you leave the car unlocked that someone else is going to come along and lock it  on you 

Should not be much of an issue from my own experience having done what you are suggesting for 50 plus years 

All is good —unless someone needs a 63 or 64 interior part for there car and they are a criminal and you interior is just the right color ( Oh never mind ) 


Some of the part suppliers on this site should be along and possible they could have the keys  cylinders and info you are asking for about the cylinders 


Karl, I have lock sets available.  From the factory, the door and ignition key are the same.  Trunk and glove box are the same.

I have just the doors or matching sets.  email me at

Short lock cylinders are for sedans, long cylinders for coupes & convertibles. I have the door locks with keys but not with matched ignition switch for $25. My email is
