Internal failure of the ignition switch may create a condition where the key reminder continues to chime even though the key is removed. In addition, the doors cannot be locked with the keyless entry system. Replacing the ignition switch with an updated switch is the typical repair.

Car thinks key is still in place and provides the corresponding beep. Key fob will not lock doors.

If I take the key out fast, the ignition switch stays in a key inserted state. This results in door chime staying on and prevention of fob locking mechanism. Replacing, slightly rotating and removing the key corrects this.

Mazda 6 When key is removed reminder chime still rings, key FOB will not operate. Juggling the key will make the problem go away.

Car constantly chimes thinking the key is still in ignition, now it has started to affect my starter, i have problems turning the key in the ignition. This was most recent and yesterday my steering wheel started making a clicking noise when I turn the steering wheel!
The key reminder chimes even when key is not in ignition. I have to manually lock and unlock door with key.

This problem happened to me, but the solution was quite simple. There was something wrong with the fuses. Fuses are only like $5 each.
