Advice on lubing door locks

[pagluy]

All my locks keep freezing shut. I put some loctite de-icer & lube in the driver door and now it's fixed, but how do I add the lube to the other doors with no key slot? Doesn't look like there's a good spot to spray it where it latches to the frame.

I would not use any lube in the key way other than a zero residue spray cleaner, electronic contact cleaner....Gun Scrubber works well also. As for the latch, white lithium grease spray for all latches, hood release, and trunk release.

My F-150 had issues with the locks. I tried lots of things to get the keys to work properly. Hands down, without question PB Blaster was the best by far. One shot in the lock keeps it free for over a year.

+1 on the white lithium grease. It is still working great after about 6-7 months.

Thanks guys. The old farts I work with were all telling me other stuff that didn't sound like the best idea.

I've only had the problem on one vehicle in the past. I used good ol WD-40. I coated it thoroughly and never had a problem again. Your mileage may vary.

Mileage definitely may vary. My last LS didn't have this issue once, and I've only ever had it in the past when there was a coat of ice covering the car. With this one it's every night, and can and does happen to all 4 doors. Maybe all my other cars previous owners always put on the grease...
