Driver door lock issue

Has anyone experienced the key not being able to unlock the door manually. The key still works the ignition no problems so I think the tumbler inside the door lock has adjusted itself. Looking for advice on how to readjust the tumber back to except my key again.

Thanks

If the driver's door manual lock is seldom used, it may have "gummed up".

A shot of WD-40 into the lock from outside will usually free up the mechanism.

You can also try some powdered graphite in the lock. Available at your local hardware store and it's made for locks.

I tried the lub thing with various products with no results. It also seemed that when using the key fob the door would not unlock or lock as well. Im thinking either the tumbler is messed or the entire unit. I have it apart and with just the cartridge alone and the key it still will move freely.

So do you think a new unit is required?

Sounds like the inkage to the latch s stiffening up. Check the rods for binding

took the unit apart. The "linkage" was messed up pretty bad. Replaced the guts with a series of # 2 and # 4 linkages. Also due to the crap weather in Canada I packed the unit with white greese. Just got to put it back into the car. Thanks to those who helped me out. Now just got to figure on how to get the picture attached to my profile chat area lol.

Take the opportunity to graphite the lock as suggested above. I found that to be the only long term solution to the tumbler seizing up.
