I have a '98 LC with 105k mi. Reccently I became aware that the drivers door won't lock / unlock with the remote but the other ones will. The lock knob on the inside driver door won't budge if you try to manually do it that way. Inserting the key in the lock or using the interior switch is the only way to lock / unlock the driver's door. I tried the spare remote and still no luck. Any way that this is an easy fix? Anyone have experience with this and know what the dealer would charge?
