Freon goes in the ac system and is adjusted to an operating system pressure for the gas in use. If you need to add gas then you have a leak so it would be a good idea to visit an accredited ac specialist shop to find and fix the leak and have the correct amount of gas added.

Assuming its an E-Class.
have a look at the inside of the door where the lock catch is, there should be a little bung over a hole. remove the one on the same hight as your door handle. under it you can see a hex key bolt. Undo this bolt and the 'key lock' can be withdrawn outwards seperate from the door handle.

If it is from wear in the lock cylinders or dirt, get someone who fenced epee or foil ( I kid you not) the motion of "picking up the blade" and counter is what I use for such situations of a stubborn lock with great success. it is that subtle wrist motion that makes the difference.
