    Default My keys don't work in my car doors??

    The wife and I went to an outdoor show Sunday and I locked my doors for the first time since buying the car back in October 2006. We come back to the car and the keys won't unlock the doors ? It works in the ignition and the round key works in the trunk and glove box. Does this mean my doors were changed back when it was painted 20 years ago?? Has anyone else experienced this? Is this something that a competent locksmith can easily change without damage?

    Yup - my 70 is the same way. Someone in the past changed the steering column and not the ignition. At least I have the keys. I don't know if it would be easier to change the doors or the ignition. I would likely change the door locks. Year One or OPG might sell repro's, or watch ebay for a set with keys. I suspect any 1969 GM car will fit. You will carry an extra key, but I don't mind. Makes it a little harder to steal the car.

    I am no expert, but you might be able to get the code off the lock (I think they are stamped???) and get keys made, but by then you have the lock in your hand and you could just replace it.

    All of the locks are easily re-keyed by a locksmith. I updated all locks (including ignition) on my car to work on a single key.

    Scotty,
    Pull off one of the door panels, and remove a door lock. Take it with your trunk key to a good locksmith and have him keyed to the trunk key.

    At least you weren't a bonehead like I was.

    I had forgotten that the ignition key is also the door key on these cars, after years of using a round key to unlock my car doors.
    For a couple of years I wouldn't lock the car. I assumed someone had changed the trunk cylinder.
    Then, one day out of nowhere it dawned on me.
    The ignition key also unlocks the doors!

    Right remember the old GM's like our GS's used the door key for the ignition. I am not sure 100% but I do not think you can key the doors and the trunk. BUt you can key the trunk and the glove box

    Default Re: My keys don't work in my car doors??

    I had a similar problem when I got my car. I had three sets of keys. All round trunk keys worked, and all keys square keys worked in the ignition. However, only one square key worked in the doors very well. I went to a locksmith, and he thought that they were not original keys. When keys get made several times, from copies, the prongs and squares, become rounded and not sharp crisp angles. To make a long story short, he was able to match up the keys in some sort of books, and find the correct code, or something. Now I have 3 sets of perfect keys, that work like butter. Not saying that this is your situation, but it would not hurt to check, before rekeying everything. Unless you want to. I am sure not all locksmiths are exceptional, but this one seemed to be. Good luck.

    Regards, John.

    Cool - more good posting - so find a good locksmith. If they say "GS what???", look somewhere else! Also, if you need help getting to the locks try a competent body shop. They usually have mechanics that do that kind of work.

    Sometimes the keys and locks lose the ability to match up. they get worn done and stiff with age.I have one original key that doesn't work on the passenger side, the other key does, they both work on the driver side.

    Good points.

    My trunk key won't even fit into the door lock. I am using a set of copied keys. I put the originals away for safe keeping.

    I'll try the originals in the doors (Thanks Johnny)

    On the cars like ours the ignition and doors were the same key the trunk and glovebox is the same key. The round trunk key should not have the same grooves and flats in the side of the key not the actuual tumbler strikers. If a set of later locks were installed then you might be abe to use a round key.

    Exclamation Re: My keys don't work in my car doors??

    Square key = Ignition and doors

    Round key = console, glove box, trunk

    That is the correct GM way from 68-72.

    I think it has been well established that the square key works for both the doors and the ignition. And the round key for the trunk and glovebox.

    That was never at issue, at least how I read it.

    Scotty,

    That is awesome news! No need to re-key, or sell. Ha, ha,ha. Take your originals, to a real locksmith, A.S.A.P. Don't have the 18 year old, at the ACE, make your new sets. I am convinced that there is a difference. It may cost a few dollars more, but nothing is too good for you and your "baby".

    You may even get some real G.M. marked keys, at a locksmith. They might have some old stock at those places, my guy did.

    Regards, John.

    Johnny,

    Normally, when I drive my Buick it is to a car show or else I pull it up front at the place and leave the windows down and unlocked.

    The next time I go somewhere where it should be locked I'll bring the originals.

    Thanks buddy!!

    Most good, real locksmiths can do it all. You can take your car in and they know how to take off the panels correctly, and in my case, they took the tilt column apart and changed the lock cylinder for me when I added a tilt column.

    While I read it as some people might not know that the older Gm used the square for the door and the ignition. I will at this time admit to maybe having a few cold refreshments before reading the thread. But still I was right , right?

    Trunk lock went bad on my GN recently. Key opened the doors but not the trunk.

    I had a new trunk lock on hand, but it would obviously needed re-keying before I installed it.

    Took both locks to a real locksmith who said my old key was worn out and crummy, and he couldn't re-key to it. I told him I'd check around the house for a better one.

    Three hours later, he calls me back, says he just went ahead and looked up the correct GM codes and re-cut my key and the others to factory specs. All keys now worked both locks, plus he freed up the bad original.
