Frozen Door Lock

[Yardsale]

I have a '98 F-150 and the driver side door lock wont turn. The passenger side door lock will turn unless it's cold out (<50°F). I have the same low temperature problem with my '01 Job 1 ST on the drivers door lock. The remote and keyless entry both work fine.



Any idea what the heck is this??

Spray some WD-40 inside the cylinder.

I tried that on the F-150 and it didn't work, but I haven't tried it on the ST, so I will.



Thanks for the reminder ("duh")!

Better off using lock lube... WD40 is great for 1 thing,, attracting more dirt and dust !!!!!!



Also i noticed on many fords you have to wiggle the key while turning and even push it in harder or pull it out slightly from the bottom and turn...

Ya Todd, I have done the key wiggle dance, but with little success.



Maybe I'll open it to see if I can tell where it's hanging-up.
