I have a 2012 Buick Lacrosse that the key fob or the key itself will not open the doors or trunk. How can I get in this vehicle? ---

There appears to be a lock cylinder in the drivers door handle, press the button on the key to extend the key blade. ---

> [@Steve19](#): > > key fob or the key itself will not open the doors I have found that if the lock cylinders are not used for a number of years, they can stick. I know you shouldn’t use WD40 on locks but still it might help free up the cylinders. Then once a year work them a little. Or call a lock smith. ---

Might be a dumb question, but have you ever been able to get into the car? ---

If your physical key , inserted directly into the door lock cylinders, won’t open any of the doors, you’ll have to visit a dealership. There, you’ll be asked to to prove you own the car. If there were another way to do this, the car’s locks wouldn’t be effective at keeping out thieves. ---

When I couldn’t find graphite at the store I bought this product, and the difference in how smoothly my locks (home, auto, mailbox) function is nothing short of amazing.

I’ll have to look, but hopefully it’s a little cheaper than $72 for two on Amazon. ---

When I bring it up onscreen, it shows $5.24 for one can of Houdini lock lube at Amazon. I think I paid about the same price at Lowe’s. ---

Figured as such. Never know though in Minnesota. I get the same thing with Menards sometimes where the price lists in the thousands for something. Maybe a private seller trying to make lunch money. ---

Also, the price from the same Amazon seller can be variable–within a matter of just a few minutes. My brother pointed this out to me, and I have confirmed it. ---

If you don’t have any of the dry-lube product, one work-a-round is to rub the key a little with a pencil lead. That will get some graphite on the key’s surface, some of which will transfer to inside the lock. ---

I don’t think the locks are the problem . I think they do not know there is a key in the remote fob that fits the door lock. But I doubt if we will ever hear if that is correct.
