Key & lock issues 1972 250 sedan (W114)

Scratching my head just a bit.

Okay - I received one key with the car (1972 250) and it works just fine in the ignition, but not in the door/trunk/glovebox locks. (Feel free to laugh at me - I've only just discovered this - have had no reason to lock it up since bringing it home in January but now I want to head out on a bit of a road trip so securing my stuff at least in the trunk would be a Very Good Thing.)

As I understand it one key should work on all the locks for this year/model, UNLESS I have a "Valet key" in which case it should work in the doors and ignition but not the glovebox/trunk.

But the key won't work in either door (and yes, I've tried every which way & wiggled it and teased it and even forced it as much as I dared). The key will turn the lock buttons just fine - though a bit stiff - but no "click" happens.

I am left wondering if the ignition was swapped out at some point.

So I'm thinking the best solution will be to have a new key cut for the doors/trunk/glovebox, assuming these are indeed all the same. Talked to a locksmith and he says to bring in one of the tumblers and he can re-key it for me. So now I'm wondering if any of you MB experts can give me a few pointers on how best to go about removing said tumbler. Anything I should know before I start poking around?

Or any other words of wisdom on the key/lock situation greatly welcome.

I own a 1969 250, one key works in the ignition only and the other key works in the door, trunk & glove box only. I think you are missing the door, trunk, glove box key. I don't know if the keys were different for 1972.

A 1971 250 should be a single key system. Sounds like the ignition lock was replaced. Get the datacard for the car and it will give the original key code, which will probably match all of the other locks. Then order that key (from MB or from key-men.com). That should open everything else. The key code also might be on the side of the glove box cylinder (easy to remove) or on the inside of the door locks (also easy to remove).

I have no suggestions regarding re-keying the ignition to match the rest of the car.

Thanks for the responses.

Thank you both for the responses!

I'm going to go with the "2nd key" plan - no problem packing 2 keys - will pull one of the lock cylinders and see where that leads me. Local locksmith said he could make me a key from that so I'll try him first - otherwise will see if I can order the correct one.

Good to get the confirmation that the 1972 car should have only one key for everything - that's what I thought so was surprised when it didn't work on the doors. The ignition has probably been swapped out sometime in the past 40+ years - logical explanation.

Cheaper and faster to order the key cut to code - maybe $14 total. Just FYI. Plus no labor on your part.
