Post subject:  Can I have a trunk lock that uses an ign key
I was wondering if anyone knows of any trunk lock that uses an ignition key blank instead of the normal trunk key. I would like to only carry 1 key if possible. The car is a 1965 so it would need to be the key blank from that era. Thanks in advance.

This isn't practicable, no. The key blank is entirely different in its profile, so it's not just a matter of having all the lock cylinders equipped with the same tumblers. You could probably figure out a way to do this but it would involve spending a great deal of money and possibly defacing your car. Best and easiest solution is to keep on carrying 2 keys...or rig up a remote trunk release so that you can use your one-and-only key to get into the car to press the button!

I think I have to disagree with ya Dan. I have 2 different locks on the cargo doors of my van, and I have talked to 3 different locksmiths on this subject and was told by them that it can be done. And would cost about $20-30. Now, if only I'd get off my lazy butt and yank it to have it done is another story.

I rigged up a remote like on new cars (a remote with the lock, unlock, and trunk buttons) so I can just open it with that. The lock button pops the drivers door open, the unlock button pops the passenger door, and the trunk button pops the trunk :).

I did this because I shaved off all the door handles and locks so the remote or the hidden button on the car is the only way in (short of reaching in the wing window and popping the inside latch). There is also a button for the trunk mounted in the glove box so I can reach int he glove box and pop the trunk that way.

Cargo doors are doors, not trunks. The locks used on cargo doors are the same variety as those used on driver and passenger doors. That's not the case with car trunks, which use a totally different lock.

I have to disagree too. I had my car with only one key for the front doors and trunk, with minimum adaptation required to make a door cyl work in the trunk. Now I got a correct 2 keys combination front door locks/ignition and trunk/glovebox at ebag for under $50, NOS stuff with 2 keys each set.

I find it hard to believe you can't rig up a door lock to open the trunk. My ignition and doors use the same key. Are door locks that different from a trunk lock that you can not put one in the trunk?

Why not have a lock smith just change the tumblers in the trunk lock cylinder?

The '88 Diplomat Cop Car I had use the same key for door, trunk and ignition. From what I understand, the police departments specifically requested them that way.

At the same time, I think what Dan is saying is that if the horizontal grooves in the keys are different between the two kinds (door and trunk), then it isn't as easy as just swapping tumblers to match.

Sure was handy on that Dippy. Chrysler must have figured that out later as my wife's old Status was the same way.

DionR is absolutely correct. My '68 Dart is currently a 1-key car, but I had to make a modification to make it happen.
I did this back about 25 years ago, but there's no reason, assuming you can find what's needed, that you can't do it today.
Chrysler fleet vehicles were 1-key cars. If you can find an old taxi/police/etc. car, the trunk lock mechanism should go right in place of yours.
Mine happened to come out of a '74? B-body taxi, was re-tumblered to match the key for my ign/doors, and it's done good ever since. I'm not even going to venture a guess as to whether one can still get the lockbody/cylinder from anyplace, though.

Not a problem for a good locksmith. I had it done on a Charger I had; it cost me $30. Then I ended up shaving the lock anyway, like ross did; I still have it stored in a box somewhere...

Door lock turns both ways from neutral/key-entry position, and is not spring loaded, and turns a bellcrank. Trunk lock turns one way from neutral/key-entry position, is spring loaded, and turns a longitudinal rod.

That said, I find P/Ns in the 1985 FPC for single-key lock cylinder packages for Diplomat/Gran Fury cars as follows:

4172 957: Pkg, Cylinders w/key, police/taxi, door, deck lid, glovebox; w/single-key, w/o tilt steering.

4246 763: Pkg, Cylinders w/key, police/taxi, ignition, door, deck lid, glovebox, w/single-key, w/o tilt steering, up to 1-2-85

4378 030: After 1-2-85

4196 943: Pkg, Cylinders w/key, police/taxi, ignition, door, deck lid, glovebox, w/single-key, w/tilt steering

Seems to me buying any of these numbers would get you 80 to 90 percent of the way there.

Different longitudal groove patterns, door key won't go into trunk cylinder

My 65 Coronet (which is in the process of being parted out) uses the same key for the trunk as the doors and ignition. Also used the remote release from an 83 Imperial for use while inside the car.

I understand how the locks turn, the latch only turns one way so even if the lock can turn both ways the latch would disallow this, so a door lock could be used by simply adapting the rod to fit the back of the door lock.
