Door, glovebox, and rear trunk locks cross reference to other chassis?

[drooman]

Recent acquisition came with ignition key only. Can door, glovebox and trunk locks come from a 111 or 112 or 114 chassis or ?
This car is later production 250SL with VIN  over 4900. Thanks for any insights here.

Is it 250SL or R107?

[drooman]

Typo in my first post, now corrected.

W113 68 250SL with VIN over 4900.

I think that as of chassis number  043 002979 you are supposed to have one key for all locks.

Not sure if this works on a late 250SL, but on my early one, the key number is stamped on the handle casting.  You may also want to get the data card from MB ($$$); that will have key numbers.

Are we sure about this? pretty sure my car has the older style lock types requiring the smaller keys in the glovebox doors and trunk. It is a bit of a mongrel though as it has a 280SL engine, so other things could have been swapped around.

Where on the casting? As in "handle removed from door to see it" location?

I think if your ignition key does not open other locks, someone might have messed around with them.

That was the case with my car - I tool all the locks to the locksmith who made them fit my ignition key. This was after I checked the ky number on the data card and the locksmith confirmed my key was of that exact number.

One other thing to keep in mind - after purchasing my car (came with 1 key), I couldn't get it to work in the trunk, and I was all set to have the trunk re-keyed, until I remembered that the car originally came with a valet key too, which won't work on the trunk. So I ordered a new master key from the dealer, and lo and behold, it works everywhere. So I had been driving around using my valet key all the time!

Careful - I have a very late 250 with all original keys - THREE keys.    I "think" the change to ONE key was later in the 280 years.

You can order new set of keys from Dealer/classic Center.   Very cheap.  If your locks are original, you will be good to go - if they are not, the dealer keys may not work.

Yes!

I don’t know at what point the single key was introduced.  My 280SL (007749, Jan 1969) has three keys.  The change to ONE key came sometime after my car was produced.

Good you chimed in. I am not 100% sure if what I stated was true - about the change at chassis 043 002980 was based on this (among other pieces):

For ignition:
A 000 460 00 04 LOCK CYLINDER WITH MASTER KEY Plantinformation

and Plantinformation: As of ident. no.: 043 002980

Then there was another change of some sort that I have not yet figured out at chassis number 044  0 12690. At this number there is a difference in part numbers for:
Lock Cylinder Ignition
Cap on Lock Cylinder
Master key (there is a part number until 012690, but I do not see part number after).

For door:
One change happened at 043 002980 - door handle and lock (door handle as a whole assembly)
At that chassis number the door lock itself changed and so did inner handle and safety lock.

Another change happened as of 044 010356 - for door handles and a key as a part

For trunk:
Change of lock (whole assembly) happened at 044 010356

For glove box:
Change of lock at 044 010356
Key - same chassis, I do not see part number after 010356, all notes say it is the same as trunk key

Now it is a question of interpretation of these changes. What I thought was that the main change happened at 043 002980 and then there was a introduction of the master key itself. The changes in door, glove box and trunk at 044 010356 were related to other elements of assemblies as there was no change at that stage to the master key.

But what I am beginning to think after your posts is that at 043 002980 a master key "future idea" was introduced only, starting from ignition lock that received a future master key and that this master key idea might have materialized at 044 010356 for other locks.

Awesome information everyone. Thank you.

[Pawel66]

Not so awesome, I am afraid, I might have not given you precise info and we are not sure (yet) when the change happened...

[drooman]

Im new here, but I am very well known in the rennlist Porsche forums under the same user name. In the 928 forum we have collectively been deep diving into the minutia of technical info, running productions changes, history, etc for many years. Porsche produced many conflicting documents and procedures over the years especially the further back you go, and the real world observations of individual cars continually reveal production "irregularities"

Any MB model from the 1960s is sure to have similar characteristics.

I am very happy to see a similar level of commitment to the constantly evolving correct information and to the willingness to jump in immediately to help the new guy here ... it's the same in the 928 forum.

I am not new to pagodas and hope to be able to contribute where I can here as well.

Next stop: dealer for data card, and im going to take a crack at their key service.  With Porsche cars from the 70s the Key by VIN system seems to average around a 50 percent success rate.

[Pawel66]

I was checking on your original question of lock cylinders fitting from other models.

Ignition - yes, vast majority of models have the same part.

Glove box for 113043: A 110 689 00 01 LOCK
SAME LOCK AS REAR LID LOCK STATE LETTER AND NUMBER OF LOCK WHEN ORDERING

Used in: 108, 110, 111, 112, 114, 115

Door locks are specific to W113. Can the cylinders from door handles be used for w113 - I am not sure if they hey were exactly the same. Someone with more experience may say this.

But as you say: datacard first. I ordered mine from the dealer, just had to prove car ownership.

You could try the Classic Center for the data card and keys. I ordered keys from them using my datacard keycodes, and they were reasonably priced, but only one of three worked (echoing your Porsche experience).

I looked through the list of changes for the 280 SL (Pagoda World 25) and there was no mention of the key change, although there were a number of ignition and key related items.

There were quite a number of changs made to the US cars for the 1970 model year, at VIN ending 11948, June 1969. My 280 SL is VIN 12730 and it has the single key.

[Pawel66]

Yes, for the US and Canada market the changes were:

For ignition:
A 000 460 00 04 LOCK CYLINDER WITH MASTER KEY Plantinformation

and Plantinformation: As of ident. no.: 043 002980

same as the other markets,

and then the same changes as for the world, but a bit earlier, not from 012690, but from 0 11948, as you say:
Lock Cylinder Ignition
Cap on Lock Cylinder
Master key (there is a part number until 011947, but I do not see part number after).

The rest - doors, glovebox, trunk lock - same as the other markets, change at 010356.
