x2, are we talking those thin fridge type magnets? They don't stick to mine either, im assuming he means a much stronger magnet of some kind, that can get past the non magnetic materials.

A fridge magnet might as well be a piece of paper for how much it wants to stick to a MB door lock.

can we get some pics of what you use vstech?

ps. I just took a brake cleaner spray straw, stuck it in the door key hole to keep the flap open and blew in there with a leaf blower. Lot's of water came out of the driver's lock but none from the passenger lock. It rained yesterday but has been dry for the last 12 hours and the car is parked on a level driveway. The water seal on the driver's lock is not working as well as the the passenger side and that is the reason why my driver's lock is the one that freezes.[/QUOTE]

It makes sense the driver's lock is the one that takes in water since that is the one that is used most and the water seal is worn.

Hmmmm. you guys are right. the MB locks must be stainless... my pickup truck is Gm, and it sticks just fine... I guess some tape would be a solution for the MB... I don't wanna put tape on my MB though...

Velcro rubber band not gonna work due to shape of the lock handle. This is my temp solution till I find out why so much water is getting in. Bicycyle inner tube and hooks made from plastic house eaves vent (plastic won't scratch da paint)




Tie inner tube to clips.


Installed on lock. I think it will keep the water out (rubber is stretched over the lock and hopefully make a good seal). Only testing will tell.


Fold back to insert key. If I paint the white clips black, it will stand out less.

It got up to 40 degrees here so I thought I would take advantage of the heat wave and pull the drivers door handle and see what there is to keep water out of the lock.

There is an o-ring, and it was in three pieces when I pulled the lock cylinder out. My 300D's lock cylinder is loose in the handle, so I imagine that the o-ring is totally gone...

I made a new o-ring using 2mm cord, it fits snug as it should. The only other seal is the gasket between the handle and the door. I am hoping that replacing the o-ring in the 300D will end the problem once and for all..

For those with frozen lock problems and do not have time to replace the o-ring, my inner tube lock bra idea worked perfectly. Last week it had rained hard for a day then dropped 50 deg to below freezing overnight- a perfect recipe for frozen locks and my lock didn't freeze!

I’m not sure how to say this without it sounding the wrong way... but although I have no doubt that it works well, it's appearance is lacking the minimum lever of elegance that I personally require lol...

All in good fun..

Given the choice of not being able to get into your car when you have to due to a frozen lock, or a lock lacking in appearance, which will you choose? I know my choice. To each his own.

I don't feel like taking the door apart to fix the o-ring in the middle of winter. This ugly temp solution does it for me just fine. Took me 15 minutes. Scissors, inner tube, hot nail to make the 4 holes in the plastic hooks.

Updating this old thread. I installed a keyless remote door opener in my 85 300D this past summer which also solves the lock icing problem, until the door actuator solenoid crapped out a month ago and this rubber bra did it's job with no frozen lock incidents through the crappiest wintry weather. I will fix the solenoid when it gets warmer but for now, simple is better.

I have been locked out of my car due to frozen locks and standing outside in freezing weather, staring at my door, trying to figure out what to do, blood pressure rising, is much less elegant than the contraption in the picture.

Can't say I've ever experienced a frozen lock. Beyond a layer of ice on the outside that I can easily bust through with the key...

Every gas station in Canada sells lock deicer. It's just alcohol. Pour some rubbing alcohol in your lock if it's frozen. Or gas tank antifreeze. Or hell, maybe even antifreeze would work.
Be sure to spray it out with silicone spray lubricant afterwards.

Instead of a door handle bra, I just carry the $2 bottle of lock deicer in my coat. My door handle is missing the little flap over the lock cylinder so it gets full of water at the car wash. One squirt of lock deicer clears it within 10 seconds.
