Why does key stick in door of 2003 Honda civic?

Answer 1

If you have trouble unloking the door with your key, that's because the lock cilinder components have wear of the constant use of the key. You have to rebuilt the cilinder or you can what I did, exchange it with the lock cilinder of the passenger door. It is a little hard to get the lock cilinder out of the door handle. Here is a link to a bulletin service.

P.S.

If you want to exchange it with the passenger lock cylinder, when you take both of the cylinders out , remove the spring an retainer on both, then you insert the key in the cylinder and the cilinder will come out of its housing (step 18-19), the you will put the passenger's door cylinder in the driver door cylinder housing, and the driver's cylinder in the passenger's cylinder housing, and install them.
