This is something which you will need to refer to your owners manual. If in the event your lock is frozen, DO NOT force it.

Tools/Supplies Needed:
-heat gun or hair dryer
-lock deicing tool
-lock deicer
-Vaseline or petroleum jelly
-WD40
-hand sanitizer

Procedure:
-using a heat gun or hair dryer, you can either heat the lock area on the door, but be careful not to damage your paint
-the heat gun or hair dryer can be used to heat the key which can be inserted in the door afterwards
-a lock deicing tool can be used, which works similar to a key and can be inserted in the lock
-it is a heated element, which emitted heat in the lock that melts the ice.
-lock deicer can be also spray inside the lock assembly
-the trap door on the lock does need to be opened when spray the deicer in the lock assembly
-with vaseline or petroleum jelly, this can be applied to the key, then insert it into the door lock and wiggle it around until the lock frees up
-WD40 is a moisture disbursement penetrating oil
-again like lock deicer, you will need to pop open that trap door in order to spray it in the lock assembly
-let it sit for a minute and this will melt the ice away inside the lock
-a proper lock lubricate will have to be applied afterwards.
-hand sanitizer can also be used to melt the ice away because it does contain alcohol
-just like the lock deicer or WD40, the trap door will need to be opened in order to apply it within the lock assembly

DO NOT USE HOT WATER TO MELT THE ICE AWAY IN THE LOCK, THIS WILL MAKE THE SITUATION WORSE.
