I've been having problems with my intelligent access key feature too—for locking only. Originally, I thought it was cold weather related but it unlocks without any problems, no matter how cold. Not wearing gloves for that to be a factor. The locking feature worked fine when I got car last month, but it's worked less and less consistently to the point where I can't get it working anymore—even if I unlock the doors successfully right before it with my hands in the same position. I've been observing it for the last 2 weeks, making sure that it wasn't user error. Taking it to service on Friday, fingers crossed they can replicate and fix the issue at the service department. I'll post an update here. Anybody else having problems with only locking or unlocking but not both?
