De-icer works in the short-term . . . not good for long term. When you're car was built, it undoubtedly had some sort of lubricant in the lock, linkages, latches. Alcohol based products will remove that. Once the door is unlocked, some people swear by WD-40......I prefer lock graphite: the auto parts store will have a little container of a graphite/lubricant mix made for the purpose.

We don't help things: now that most of us have key-fob remote openers, we seldom use the keys to unlock the doors.......we should from time to time. I use the key to open the "keyhole", squirt some of the graphite in and get some on the key as well.

Lock de-icers are basically isopropyl alcohol or rubbing alcohol which you can buy much cheaper at stores or pharmacies...you might have some in the medicine cabinet...buy a small squirt bottle to use as well for applying the alcohol to locks if you don't have an old one laying around. Squirt some in locks or outside keyholes and work the lock/key after a few minutes or so.The alcohol will melt any ice in the locks.

After the alcohol is evaporated., spray down the locks with WD-40 which displaces any water or moisture and prevents refreezing.

You first need to use a blow dryer or heat gun on the edge of the door aimed at the latch. This takes care of the frozen mechanism. Then hit it down good with WD-40 to displace any remaining moisture and lubricate the latch assembly. Put the straw that comes with the WD-40 into the key hole as well and soak everything down until it's a mess. Then clean things up'

A lock de-icer works wonders. I spray it in all my external car locks twice a year and never have an issue with frozen locks or lock cylinders seizing ( a common problem with remotes since most people never actually use the key to unlock the door until the day that the remote stops working ).

There are even some electric de-icers around designed to thaw iced up car door locks by inserting a heated copper rod into the key slot. Such products can be very helpful and usually need just two ordinary batteries to operate!

Here it is sold as Lock De-icer - a small can with an aerosol spray. If you are somewhere very cold, you can also get little battery operated gadgets that you stick into the keyhole and the warm it up.

WD40 is a good water repellent, beside being light oil. Spray into the locks using the straw supplied with the can and wipe away the excess from paintwork.

Spray the rubber seal around the doors with * CRC Pure Silicone Spray. Walmart Automotive section has it.

It sounds like there is a lot of old dirty grease in there. You will need to use something to clean the grease off (alcohol or petroleum based) and then put the proper lube on it.

WD40 or just warm the key in your hand a few times and insert it a few times should work

WD40 once it has de-frosted as it is a water dispersant then you must grease them properly again to stop it happening again. Usually caused by people de frosting their car by pouring water over it.

WD-40 will work fine.
