Driver's side door won't allow the key all the way in and will not turn. Tried WD-40 and also some graphite. I loosened up a bit, but still can't get the key to work. I called the local dealership and they advised using my second key or the valet key. The primary key shows no sign of wear and works fine in the passenger door lock. Should have gone keyless!!!
Driver side door locks doesn't lock or unlock using key. However passenger door and trunk door opens fine with same key.
The drivers side door became difficult to insert the key into about a week ago. I was able to unlock it with a little bit of wiggling of the key. Then the key stopped going into the keyhole at all. I can't unlock it and have to reach over the passenger side to unlock the door on the inside.
Door lock will not turn with key . Can't get the key in the lock..
door lock problem ,key goes half way in and thats it.sounds like a common problem to me,needs to be a recall.
Same as everyone else, key doesn't work on drivers side.
Driver's side door lock sticking -- sometimes works, sometimes doesn't. Key won't go in or will go in but not far enough to unlock door.
key does not turn in drivers door
The doors locked me out completely. The keyless entry would not work and neither did trying to manually unlock the door. I had a to get a locksmith to let me in. I've had other problems with the locks in the past. I have an appointment Monday. Hope it works out. There was a class action lawsuit settled last year about defective locks on Honda CRV
Ignition lock failure at about the same time we noticed the door looks were getting bad. Ignition lock replacement was in the $500 range. We ignored the door locks; until now, when some miscreant violated our interior space. Three locks, all going bad; at the same time. Something stinks in Hondaville. Have appt. w/ dealer today.. Hope to file a happier update...
Just picked up my 2009 Civic after 3 days in Honda repair -- was having trouble w/key in driver's door - wouldn't always lock/unlock but was able to deal with it. Door lock tumblers have already been replaced once about 2 years ago. Saturday the keys wouldn't work in the ignition. Car had to be towed. Thankfully the problem occurred locally. DX: worn tumblers. $890.00 later - all new locks/tumblers. Hope this is the last time with this problem otherwise could be the last Honda I own...Will be sending letter to Honda with a copy of the invoices for both replacements. It will be interesting to see what they do.
Same issue with lock. THis will be second time to replace it. Never had this happen with any other car I owned.
I can only unlock the passenger door but the key doesn't work in the trunk or drivers door. I have a 2003 Honda Civic coupe ex
I have a 2009 Honda Civic with manual locks. The key will not go into the lock on the drivers side.
The 3 keys I have will NOT open the drivers door BUT will start the car, open and lock the glove box and the trunk!
Takes a couple minutes to unlock driver side door handle. Lock seems to be worn out.
If the second time I have this problem. The first time was 6 months ago and the lock smith make one different key just for the door. Know is the same. I sure this must be part of recall
Same as everyone on the drivers door.

Honda should fix these problems before someone gets locked in when in an accident and looses their life.
The driver side key won't go all the way in, I have to wiggle it around for a minute or two for it to go in, such an annoying problem out of a car that is supposed to be reliable, Honda does not take ownership of their screw ups, planning to sell both my Hondas and will give Toyota or Nissan a shot this time.
Key wont open passenger side door and wont go in all the way. Driver side door lock wont turn or un lock except from pulling lock up by hand from inside of car and wont lock unless i pull up on handle
