My car doors won;t open - think they're frozen

[TooTiredtoGoogle]

What's the best thing to do?
Pour hot water over the handles? Or will this cause some kind of damage I might not have thought of?

Hair drier?

WD40 squirted in the lock?

I had this today. Run a credit card around the edge.

Oh sorry is it the lock? Mine were frozen shut around the edges.

Oh is it the lock that's frozen or the door won't open when unlocked?

hot water bottle held against the door?

Not helpful now, but I think I read somewhere that if you smear vaseline on the rubber seals it will stop then sticking next time.

I second the credit card idea - I did this this afternoon.

this happened to me today. I had to climb in through the boot, heat car up from inside and then let myself out!

anti freeze spray

I can unlock it, but not open the doors.
Would pouring a kettle of hot water over the door be really bad?

Might try climbing through the boot and heating car up from inside.
Thanks.

I'd try some hot water.
I couldn't shut mine again during the cold last week, the mechanism opened but then was too cold to close!

just don't close the boot fully until you can open doors!

don't use hot water if it goes on the window it can crack. tepid water should do it, but you will have a patch of ice on the floor so be careful

RAC says luke warm water or de-icer.

I went to see the garage which sold me my car when it did this every day when it was below zero - they suggested vaseline round the door

Mine does this (zafira). drives me mad. Am defiinitely going to try the vaseline idea!
