Door Lock Not Turning Suddenly

[shovenose]

Yesterday it was fine, this morning I took some jiggling, and now it's not turning at all now matter how long I sit there and mess with it. In GM's infinite wisdom the passenger door doesn't have a lock so the drivers door lock is the only one. What do I do now? lol the key works fine in ignition so not an issue with the key. Thanks in advance!

Hello

Unless the component broke i wouldn't know what it would be.

Before you go tearing into the door panel, you can try picking up a can of door lock lube like pictured below. It maybe dried up...


Make sure what ever you pick up has Graphite in it.

Hope this helps!

No keyless entry?

Hm... Makes me wonder if my door's keyhole ever worked, I hadn't used it in years

Come to think of it, I haven't tried my Silverado's key hole either.

Sorry, forgot what thread I was in.

But more on topic, I think I've only used the key hole maybe once in the last 3 years. Should probably try it more often to prevent a bad situation if keyless entry craps out.

Like me on my Saab, never tried the key since I bought it, always used the RKE. Then in winter, I started it with the key to warm it up and locked the doors while I went in to the office. Came back, RKE wouldn't unlock the door (some weird thing with Saab only because this trick worked with the TB). Tried the key, frozen solid, tried everything, WD40, Lock Lube, nothing worked. At 3AM, only option left was a tow truck to break into it ($140 ). When I later checked the lock itself, the tumblers were corroded solid. Nothing could free it up. Wound up replacing it with one from the pick-a-part off a Voy (key was stuck in ignition ) so I have a different key for the door.

Bought me some of this stuff at O'reilly and it's like new now

How do I add a passenger side key hole to prevent this issue in the future? Was it an option? Perhaps I can swap out a passenger size handle/lock unit from a 'voy with the option?

Also, I supposedly also have RKE but previous owner lost the thing. Do I get that at the dealership?

No, you can pick it up used or on eBay or Amazon. Heck, for this pair on eBay for $17!

For passenger side key lock, I don't think that animal exists unless someone can correct me.

Edit: Before buying the remotes, check your RPO codes in the glove box for code AU0.

You might have the wrong truck! It happens when you get old.

The passenger door key lock was supplied on vehicles without keyless entry.
Few and far between but they do exist.

@Wishbone might have a passenger keyhole then because his was as barebones as they get.

 

[Mooseman]

They should have called it the ELS (Even Less Stuff)

 

[shovenose]

Great! I ordered the pair of key fobs from eBay... I'm 100% sure it has keyless entry since previous owner told me he had it but that the thingies were long lost.

I guess I'll give up a passenger side key hole if it was not a popular option. At least I will have some redundancy with drivers door lock + RKE.

Consider yourself corrected @Mooseman

You are correct @ddgm

I do have a passenger door keyhole...

Lock is still working great, but I got my key fobs, and keyless entry works great. That's the first time I've ever had it I think I'll use keyless entry as much as possible to prevent wear on the lock, but I will still use it once in a while to prevent it from seizing up.
